ROBERT STACK: Tonight
on "Unsolved Mysteries,"

the story of newlywed
Shannon Davis

who died in a riding accident.

Shannon's husband had
purchased secret insurance

policies totaling $330,000.

In Oklahoma, Aileen Conway
died in a mysterious car crash.

The highway patrol
ruled it an accident.

Her husband believes
she was murdered.

In 1928, Glen and
Bessie Hyde vanished

on a Grand Canyon River trip.

50 years later, a secret
skeleton was found.

In Concord, California,
housewife Dottie Caylor,

terrified of unfamiliar
places, summoned the courage

to take a train ride.

She has never returned.

Our four mysteries tonight are
connected by common threads--

unexplained
circumstances, deceit,

the suggestion of foul play.

At the heart of each is
a husband and a wife.

These mysteries will
be difficult to solve.

But the stakes are high when
people's lives are involved.

Perhaps you can help.

We've recreated the events of
each story in precise detail,

in the hope that someone,
somewhere, knows the truth.

Join me.

You may be able to
help solve a mystery.

On July 23, 1980, in a small
Michigan farming community,

newlyweds Dave and Shannon
Davis prepared to go

for a sunset horseback ride.

Within an hour,
Shannon was dead.

According to Dave, Shannon
was not an experienced rider.

When they reached the
edge of the woods,

she lost control and
fell off the horse,

striking her head
violently on the ground.

Dave's simple and
plausible story

was immediately accepted by the
couple's family and friends.

I felt that Shannon's
marriage was made in heaven.

I really felt this.

I had began to love David.

I described him probably to
a lot of people as a man's man.

He was an outdoor
person, hunting, fishing.

He just was very manly
and very likable.

LUCILLE MOHR: And she'd
say, isn't he neat, Mom?

And I thought he was neat.

I thought he would
protect her from anything.

I had no idea of what
he was really like.

ROBERT STACK: After Shannon's
death, Bob and Lucille Mohr

began to discover
that Dave Davis was

not the man he seemed to be.

They began to find clues
in Dave's behavior, which

led them to believe
that their daughter's

death was not an accident.

Dave Davis has now disappeared.

There's a warrant
out for his arrest.

But the Mohrs are afraid
that their son-in-law

may have gotten away
with a perfect crime.

At the hospital, Shannon was
pronounced dead of the injuries

caused by her fall.

Minutes later, Shannon's
parents were surprised and upset

when Dave insisted that their
daughter's body be cremated.

Her request was
to be cremated.

ROBERT MOHR: And I says, can
we take Shannon back to Toledo

for burial?

Please, let's talk
her back to Toledo.

Let's take her home.

DAVE DAVIS: It's
not what she wanted.

ROBERT MOHR: I suppose
our voices were

getting a little
bit loud, because I

don't believe in cremation.

I knew Shannon didn't want that.

This is what she wanted.

I felt so strongly that if
he was going to insist on it,

I was going to go
try and find a judge

and get a temporary
restraining order

to stop him from doing it.

ROBERT STACK: That night,
Lucille couldn't sleep.

She remembered that her
husband Bob had caught Dave

in a lie about life insurance.

LUCILLE MOHR: Bob
says, David, do

you have insurance on Shannon?

He said no.

And it just shot
right through me.

I remembered Shannon coming
home from her honeymoon,

the very next day
saying David took out

a large life insurance on me.

That was the first
lie I picked up.

ROBERT STACK: Three days
later, Shannon was buried.

Bob and Lucille Mohr noticed
that Dave seemed unmoved.

PRIEST: I Bless the body of
Shannon with the holy water.

ROBERT STACK: After the
funeral, Shannon's parents

found out that Dave had
lived a life of deceit.

He bragged that he'd
been wounded in Vietnam.

His own parents said he
was never in the service.

LUCILLE MOHR: All this
was crowding in on me.

And I just-- all I could
think inside is David,

did you kill my daughter?

And it just was there.

I knew that he had
murdered my daughter.

I didn't know what
to do with it.

I felt ashamed.

I just felt like I was
going crazy inside.

ROBERT STACK: Two days after the
burial, six separate insurance

companies contacted the
funeral home, requesting copies

of Shannon's death certificate.

Her death left Dave Davis
the beneficiary of $330,000.

Bob Mohr then discovered that
Dave may have been involved

in other insurance scams.

ROBERT MOHR: He burnt the
farm down across the road.

And he had other fires
and the fake injury

from when he worked for
the automotive company.

So I think he was just out
to live on insurance money.

And he just kept getting
bigger and bigger all the time.

He started out
with a simple fire,

and now he was up to
the point where he was

going to collect big insurance.

ROBERT STACK: At Bob and
Lucille Mohr's insistence,

Shannon's body was exhumed.

The medical examiner
found the injuries

on the body consistent
with a fall from a horse.

Indications of an
unknown drug, however,

were found in Shannon's body.

But the medical
report still ruled

Shannon's death an accident.

Three months later, an article
in the "Detroit Free Press"

exposed Dave's alleged
insurance swindles.

The case was reopened.

And Dave moved to Florida.

Detective Don Brooks was
assigned to the investigation.

DON BROOKS: And the
information that

was contained in that newspaper
article was phenomenal.

I thought if this was
even 50% accurate,

we're onto something here.

ROBERT STACK: Brooks
contacted the toxicologist

who had earlier found
traces of the unknown drug

in Shannon's body.

DR. ROBERT FORNEY,
JR: I explained to him

that we had a very large
number of chemicals

that we were looking at.

There's over 250,000
chemicals in common use.

And we had searched for
and ruled out maybe 1,000.

And I said what I
need is some help.

DON BROOKS: Is that the
metagraph right there?

DR. ROBERT FORNEY,
JR: This is it.

You see the peak is right here.

Can you see how nice
and clean it is?

Because it's so clean, that
means that I think it's a drug.

This is important to the case.

It's got to be, if we can
identify what that is.

He asked me actually
for information

about Davis's background.

One of the things I told him
was that he was a dirt farmer.

And he had some large
animals on a farm.

Dr. Forney and I then
discussed the idea

of contacting veterinarians
in the area that

may have serviced Dave Davis.

DON BROOKS: I'm Don Brooks
for the state police.

I talked to you a
little bit earlier.

That's right, Don.

DON BROOKS: I happened to ask
two or three different vets

in the area if they knew of
any drugs that may affect

the muscular system
or the nervous system

that they would use
on large farm animals.

And when I did so, one of
the veterinarians I talked to

provided me the name of a drug.

ROBERT STACK: Dr.
Forney tested that drug,

an animal tranquilizer.

It matched perfectly the sample
taken from Shannon's body.

Now Brooks needed to connect
the drug to Dave Davis.

We were able to determine that
several years ago, Dave Davis

took part in a deer hunting
camp, at which members

of the camp used this
drug to hunt deer

with, with bow and arrows.

ROBERT STACK: Shannon was
exhumed a second time.

Two injection marks were
found-- one on Shannon's

shoulder, and one on her wrist.

LUCILLE MOHR: Don Brooks
called, and he said bingo.

They found Shannon is
injected with something.

And we're going to move now.

We're going to get him.

ROBERT STACK: On
October 13, 1981,

a grand jury issued
a first degree

murder warrant for Dave Davis.

Detective Brooks believes that
Dave Davis pushed or coaxed

Shannon off her horse,
wrestled her to the ground,

then paralyzed her with
a lethal tranquilizer.

Brooks believes that Dave then
struck her head on a rock,

so that the injuries
would appear accidental.

DON BROOKS: I don't think
there's any question that this

is premeditated murder.

I believe he married
Shannon Davis to kill her

and to profit.

I want to get him.

And I want him
see him locked up.

And I want him to
feel at all times

that we're breathing
right down his back.

Because I will not let go.

That can't bring her back.

But put him, put
him away, before he

does that to some other girl.

And he will, he will.

ROBERT STACK: After
our broadcast,

a viewer recognized Dave Davis
as an acquaintance living

in American Samoa, a small
island in the South Pacific.

Davis was arrested nine
days later by FBI agents.

At the time of his arrest,
Davis was living in this house

with a 20-year-old Samoan wife.

He told her that his first wife
had died in a tragic accident.

3 And 1/2 weeks later, Davis
was returned to Michigan,

to stand trial for murder.

REPORTER: Any comment on the
charges against you Mr. Davis?

I didn't do it.

REPORTER: Police say
your wife was poisoned.

I didn't do it.

ROBERT STACK: After only 2
and 1/2 hours of deliberation,

a Michigan jury convicted Dave
Davis of first degree murder.

For Shannon's
parents, the verdict

brought an end to their
nine-year struggle for justice.

ROBERT MOHR: This is
what we waited for.

And we got what we wanted.

He's going to be locked
up the rest of his life.

That's what we wanted.

But we'll go on the rest
of our life missing her.

That's why I say he gave
us the death penalty.

Now we're giving it to him.

ROBERT STACK: Last September,
we presented the mystery

of George Marsh, a Kansas
City laborer who died alone

in a nursing home in 1982.

He had no known
heirs or relatives.

But he left behind a
legacy of $175,000.

We hoped that someone
watching the broadcast

might have known George
Marsh or his heirs.

There were few clues.

A birth certificate, showing
that George Marsh had changed

his name from Joseph Zelenka
and some family photos,

including this portrait
of a young woman,

inscribed, "Your
loving niece, Eleanor."

ELEANOR TOLAR: When
I looked up and saw

my senior high school picture
on TV, I couldn't believe it.

So then, when they read,
"Your loving niece,

Eleanor," that that's how it
was signed, I was just stunned.

I was just amazed.

And then the very next
picture was Uncle Joe.

And I said, my gosh,
that's Uncle Joe.

ROBERT STACK: This
woman, Eleanor Tolar,

is George Marsh's long-lost
niece in the high school photo.

The Zelenka family lives
in Rock Springs, Wyoming.

Joseph's brother Jim has been
looking for Joe since 1931.

JIM ZELENKA: I would
never know, no idea, why

he kept away from the family.

Because there was
no hard feelings.

We were all united
always, in everything.

ROBERT STACK: The
Zelenkas are currently

waiting for a final judgment
from the public administrator's

office in Kansas City.

Jim and Eleanor plan to divide
the $175,000 among Joe's

surviving relatives.

But more importantly, they
want to preserve Joe's memory.

They intend to bring his body
back to the family burial site.

JIM ZELENKA: The money,
it don't mean as much

as finding out where he's at.

I just feel good all over
to know that I located him

and know where he's at.

And I'd be able to bring
his body back to rest

with the rest of his family.

In our next story, we'll
meet a man who returned home

to find his house empty,
the bathtub full of water,

the phone off the hook,
and his wife missing.

April 29, 1986, 10:40 AM.

A farmer in rural
Oklahoma notices

an ominous plume of smoke
rising from a nearby road.

[siren]

He called the authorities.

And 20 minutes later, the
Oklahoma Highway Patrol

arrived at the scene.

They found a burning car
embedded in a deserted bridge.

The heat was so
intense that the car

had actually melted
into the metal guardrail

into which it had crashed.

LARRY SALLEE: When the
highway patrol arrived,

a body was inside
the car at the time.

But it was a futile
exercise whatsoever

to try to get to the
car, due to the car

had already burned so bad.

ROBERT STACK: By
the time the flames

subsided, the body
behind the wheel

was burned beyond recognition.

Skid marks indicated that
the car's speeded impact

was 50 to 60 miles per hour.

To the highway patrol,
it seemed like just

another senseless accident.

A computer check revealed the
car belonged to Pat Conway, who

lived with his family
in Lawton, Oklahoma,

15 miles from the crash site.

The next day, the victim
was identified as Pat's wife

of 33 years, Aileen.

The Oklahoma
Highway Patrol ruled

Aileen Conway's death as a
one-vehicle fatality accident.

Within hours of the
crash, however, a number

of mysterious
discrepancies emerged,

which led Pat Conway to believe
that his wife had in fact

been the victim of foul play.

There is no doubt in
my mind it was murder.

And if I live to
be 100 years old,

I'll still be pushing
to try to find

the individual or
possibly two individuals,

whoever was involved.

ROBERT STACK: Pat
first became suspicious

when he returned home a few
hours after the accident.

The patio door was wide open.

Aileen's purse, which she
always carried with her,

was sitting by an arm chair.

Her driver's license and
glasses were still in it.

An ironing board was set up,
and the iron had been left on.

Water from a garden hose was
running into the backyard

swimming pool.

And most significantly,
in the master bathroom,

at the back of the house, the
tub was still full of water.

And the phone was off the hook.

PAT CONWAY: The thing that
really got my attention was

the phone being off the
hook, as though she had

attempted to make a
phone call, possibly

to the police department.

We have no way of knowing who.

Between me and the
kids, one would

say one thing and one another.

And we started
putting it together,

and right away we find out
there was no accident at all.

ROBERT STACK: Another
disturbing detail nagged at Pat.

What was Aileen doing out
on that lonely country road?

Neither of them had
ever been in the area.

And there was certainly
no reason for Aileen

to be there by herself.

Nothing about his
wife's death made sense.

Pat contacted Ray Anderson of
the district attorney's office.

RAY ANDERSON: The
first impression

that I had of this case,
when I met with Mr Conway,

was that of a spouse that was
left alone and behind, not

expecting the
tragedy that happened

and looking for an excuse
or looking for some reason

why this happened, other than
it just being an accident.

However, when you start
looking at the extenuating

and surrounding circumstances,
the way that she left

her house, then it
leads you to believe

that there is a possibility
that there could be foul play.

Pat, you want to take
that side of the road.

And I'll take this side.

And just look for anything that
might look familiar or unusual.

ROBERT STACK: A few
days later, Pat and Ray

Anderson went to the crash site,
looking for clues, any clue.

Pat, could you come
over here a minute?

ROBERT STACK: 200
feet from the bridge,

they found a church
bulletin in the grass.

This look familiar to you?

PAT CONWAY: Yeah, this is the
church building out of our car

from the previous Sunday.

And it was on the day
she was in the car.

Are you sure that's out
of your car, you think?

Yeah, I'm positive.

There's no doubt
that's where it was.

ROBERT STACK:
Aileen always drove

with the windows rolled up and
the air conditioning turned on.

The bulletin could not have
flown out of a moving car.

The car would had to
have been stopped.

RAY ANDERSON: Someone else
may have been with her.

Opened the door,
set the accelerator,

and slammed it into drive,
hoping to run Mrs. Conway off

into the creek,
and make it appear

as though it was an accident.

ROBERT STACK: As a result
of Anderson's investigation,

the Lawton district
attorney changed

the official cause of death
from accidental to unexplained.

The DA then asked the Oklahoma
State Bureau of Investigation

and the state Fire
Marshal to evaluate

the likelihood of arson.

What made me
suspicious at first

was looking at photographs
and seeing how much

burn that was in the vehicle.

This thing was completely
burnt, destroyed.

The burn was similar to that
were gasoline or something

like that was used in.

And another thing that
brought my curiosity up

was the fact that the
gas cap was missing.

And most arson cases-- and this
is documented-- have a vehicle,

the gas cap is removed.

And that was the case here.

ROBERT STACK: Informal
burn tests on dashboard

and upholstery samples from a
car similar to Aileen's suggest

the inside of her car may have
been doused with gasoline.

SONNY SANSOME: We
took the material.

And we applied a blow torch to
it, set the material on fire,

then removed the blow torch.

And the fire went out,
which is consistent with a

flame-retardant type material.

And then we took some gasoline
and soaked the material.

And then, of course, the thing
was completely destroyed.

And the point being without
some type of an accelerant

like gasoline, the fire
would not burn that bad.

ROBERT STACK: If
Aileen Conway was

murdered on a bridge that day,
one question still remains.

Why?

We don't really have an answer
for what put her out there.

A lot of theories
floating around.

Perhaps she
interrupted a burglary.

We backtracked a little
bit into the neighborhood.

And apparently there
had been reports

of burglaries in
the weeks and months

preceding this situation.

So the possibility of an
interrupted burglary is there.

PAT CONWAY: It
had to be robbery.

Whoever came in didn't
know she was here.

And once they found
out she was here,

they didn't want to leave
her to identify them.

So then this makes
murderers out of them.

If this case is solved, it
will be because that there

will be somebody that talks.

There will be
somebody that admits

their involvement in this.

And of course, I'm
a firm believer

that that's what
normally captures

the criminals is their inability
to keep their mouth shut.

ROBERT STACK: No one
knows exactly what

happened to Aileen Conway
on a remote country bridge

in Oklahoma that day.

A year later, Pat Conway is
still searching for answers.

PAT CONWAY: Even though
you're discouraged,

you keep pushing it every day.

You constantly think about it
when you go to bed at night

or get up in the morning.

It's on your mind
the whole time.

That somehow it
needs to be solved.

I'll never quit as far as
trying to solve the case.

ROBERT STACK: Next, the story
of Glen and Bessie Hyde,

who disappeared on
a perilous rafting

trip on the Colorado River.

Both were assumed
lost, until a woman

claiming to be Bessie Hyde
said she murdered her husband.

The Colorado River cuts through
the Grand Canyon, a perilous

stretch of water that was once
considered the most dangerous

in the world.

In 1928, two newlyweds
set out to navigate

these treacherous
whitewater rapids.

They were never seen again.

Emery Kolb, a Grand
Canyon photographer,

was one of the last
people to see them alive.

50 years later, when
Kolb died, authorities

were surprised by a gruesome
discovery in his boathouse

on the rim of the canyon.

Hidden in a canoe was
a single human skeleton

that appeared to have
suffered a violent death.

Whose bones were these?

And how did the victim die?

DR. WALTER BIRKBY:
One good option

would be that the individual
met death by homicide.

A second option
would be suicide.

It would be nice to know
who this individual was.

I mean, somebody is missing.

Somebody was out there.

And there may be friends
or relatives who would very

much like to know who it is.

ROBERT STACK: The disappearance
of the honeymoon couple,

and the discovery of the
human remains in the boathouse

happened almost 50 years apart.

Yet they were connected by an
article in an Idaho newspaper

and by the Arizona
law authorities.

They suggested that
the bones might

be those of the adventurous
young river rafter, Glen Hyde.

Tonight we'll examine these
mysteries of the Grand Canyon.

What happened to Glen Hyde
and his bride, Bessie?

Is their disappearance
connected to the secret

of the bones in the boathouse?

Glen And Bessie Hyde
were married in Twin

Falls, Idaho on April 10, 1928.

Glen was 27, and Bessie
just 18 years old.

That fall, they built a boat for
a special honeymoon adventure,

a trip down the Colorado
River to California,

through the dangerous
Grand Canyon.

Glen was a thrill seeker.

This journey would
mean instant notoriety.

SCOTT THYBONY: Glen wanted
to make a record run

through the Grand Canyon.

He wanted to do it
in a homemade boat.

He wanted to do it with
a new bride, who had

never been on rivers before.

And he wanted to do it
without life jackets.

In the fall of the
year, about six

months after they were married,
they were in Green River, Utah.

An experienced river man at
Green River looked at the boat.

And he thought it looked
to him like a coffin.

It was unlike anything that had
run down the Colorado before.

ROBERT STACK: The
Hydes took 26 days

to get from Utah
to the Bright Angel

Trail in the heart of the
Grand Canyon, a new record.

With the most dangerous
stretch still ahead,

they stopped to see Emery Kolb
who had already twice navigated

the Colorado River rapids.

Kolb had arrived at
the Canyon in 1902

and set about
documenting its grandeur.

His stunning photographs and
immense knowledge of the river

soon made Emery Kolb a legend.

THELMA SELF: He was very
enthusiastic about his river

trips and so proud of them.

Everybody that I know who's
interested in the river at all,

in all the years
I was there, first

came and talked to Emery Kolb.

EMERY KOLB: Frankly, I just
don't think you should go.

No woman has ever
traveled the river from--

ROBERT STACK: When the
Hydes visited Kolb,

Bessie had grown tired
of the river trip.

EMERY KOLB: Now
Especially the idea

of not taking life jackets.

ROBERT STACK: Emery
tried to warn them

of the certain dangers ahead.

He asked them to stay with
him through the winter

and postpone their trip
until the weather improved.

Glen, I just don't think--

ROBERT STACK: He even
offered the couple

his own life jackets.

But Glen refused
all Kolb's offers.

There's really
no reason to fear.

Both Bessie and I are
good strong swimmers.

Come on Bessie.

The light will be fading.

THELMA SELF: Mr Kolb told
me that he tried his best,

every way in the world
to talk him out of going.

He said you have no idea of
what you're getting into.

He said, I've been there,
and I know what it's like.

He begged them to take
life preservers and even

inner tubes.

And Glen flat refused.

He said I'm going to
do it without or else.

ROBERT STACK: Two days later,
Glen and Bessie disappeared.

Army aviators flew
into the canyon

and spotted the empty
boat below Diamond Creek.

Emery Kolb was asked
to lead the search

party to find the lost couple.

Surprisingly, when he discovered
the boat, it was undamaged.

Glen!

Bessie!

SCOTT THYBONY: The
boat seemed to be

intact-- the clothes,
food, Glen's rifle

was on board, a camera
with exposed film.

There was a very sketchy diary.

But a diary that Bessie Hyde
had been keeping was on board.

They found everything there
except for the people.

There's no sign of them.

ROBERT STACK: The bodies
of Glen and Bessie Hyde

were never recovered.

50 years later, the discovery
of the bones in Kolb's boathouse

fueled speculation.

Could these be the
remains of Glen Hyde?

And how were they
connected to Emery Kolb?

We'll get them examined.

ROBERT STACK: The authorities
turned the skeleton

over to Dr. Walter
Birkby, an expert

in the science of
identifying human remains.

He discovered that
the bones were

of a male Caucasian,
20 to 23 years of age,

six feet tall with
light brown hair.

Dr. Birkby also discovered a
bullet embedded in the skull.

What we found out from
the bullet that was removed

from the skull was
that not only was

this a 0.32 caliber projectile.

It came from a
revolver that began

manufacturing in about 1902.

2.1 centimeters.

ROBERT STACK: The production
date of the gun and clothing

fragments found with the
skeleton suggest that death

occurred in the 1920s.

During that time, only two
people-- Glen and Bessie Hyde--

are known to have disappeared
in the Grand Canyon.

DR. WALTER BIRKBY:
Somewhere along the line,

I heard a rumor to the effect
that Emery Kolb could have

murdered Glen Hyde, in
order that he could have,

I guess, beautiful Bessie.

It's so preposterous.

And that I just
can't believe it.

That he would off somebody and
then keep the damn body around.

You got verticality
on these mirrors?

ASSISTANT: Yes.

DR. WALTER BIRKBY:
We're going to have

to rotate that more than that.

ROBERT STACK: Dr. Birkby hoped
to put the rumors to rest.

He superimposed a photograph
of Glen over the skull,

to precisely compare
bone structure.

DR. WALTER BIRKBY:
Even more, even more.

ROBERT STACK: This
was the only way

to determine if the skeleton
was indeed Glen Hyde's.

DR. WALTER BIRKBY: The skull
is of a different shape

than the face of Glen Hyde.

The eye orbits themselves
are angled in a different

direction than Glen Hyde's.

The cheeks are wider.

Even the shape of
the chin is wrong.

Glen Hyde's chin was
somewhat rounded, as we

can see on the photograph.

Whereas the chin of
the submitted skull

tends to be fairly squared off.

So those features
alone, do not match.

These remains, these bones that
were submitted for analyses,

are not the remains
of Glen Hyde, period.

End of story.

ROBERT STACK: But the
story, in fact, does go on.

And the mystery deepens.

If the bones do not
belong to Glen Hyde, then

what happened to
Glen and Bessie?

The answer may lie in
the eyewitness reports

that claim Bessie
Hyde is still alive,

and that she was seen
back in the Grand Canyon,

retracing the steps of her
ill-fated honeymoon adventure,

43 years after she disappeared.

In 1971, an unknown woman
took a 20-day rafting trip

through the Canyon.

Geologist George Billingsley
was also in the party.

She was a very serious person.

She was always just
watching the Canyon

and helping out a little bit
around camp, all the time

wanting to do something.

And fairly happy, but quiet.

And pretty much to herself.

ROBERT STACK: Towards
the end of the trip,

they made camp at Diamond Creek.

The same spot where
Glen and Bessie's boat

had been found four
decades earlier.

To this day, we have
no idea what happened.

ROBERT STACK: That evening,
a river guide told the legend

of the missing couple.

WOMAN: I know.

ROBERT STACK: And the
woman matter-of-factly

revealed her true identity.

WOMAN: I'm Bessie Hyde.

GEORGE BILLINGSLEY: She told us
seriously enough, to where we

wasn't sure what else to say.

WOMAN: I killed him.

GEORGE BILLINGSLEY: But
we all figured she was

just making up her own story.

MAN: How?

GEORGE BILLINGSLEY: But
later on, we got to thinking,

maybe she really was Bessie.

Because the age was right.

WOMAN: I got a knife,
and I stabbed him.

GEORGE BILLINGSLEY:
And she never

smiled when she said what she
said, as if she really knew.

WOMAN: It was right around
here we had a bad fight.

And he beat me up.

ROBERT STACK:
According to the woman,

Glen was obsessed with
completing the trip,

no matter how dangerous.

When she tried to
leave, a fight erupted.

SCOTT THYBONY: I
got the full name

of the woman then eventually
contacted her back in Ohio.

But when I asked her about the
Hydes and their disappearance,

she denied everything.

She said she hadn't
told the story.

She said she didn't
know anybody named Hyde.

And she said she
wasn't Bessie Hyde.

My gut feeling though
is that she was.

ROBERT STACK: The mysteries
surrounding this story still

remained unsolved.

If the bones in Emery
Kolb's boathouse

are not Glen Hyde's,
whose are they?

And why did Kolb keep
them hidden in that canoe

for so many years?

The mysteries have
survived the years.

And for now, they remain part of
the legend of the Grand Canyon.

Next, the story of a
woman trapped in her house

by agoraphobia,
the irrational fear

of unknown people and places.

Strangely, she has vanished.

The Bay Area Rapid
Transit system,

known to commuters
as the BART trains,

that link San Francisco
with the East Bay cities.

On June 12, 1985, Jule
Caylor drove his wife Dottie

to the BART station in
Pleasant Hill, California,

18 miles from Oakland.

She entered the station
and purchased a ticket,

a simple task performed
each day by millions.

But this was a test of
courage for Dottie Caylor.

Dottie suffers from agoraphobia,
an irrational, overwhelming

fear of being in public places.

Facing the unknown
and the possibility

of panic shadows every step.

No one knows if Dottie
overcame her fear that day

and actually boarded the train.

What is certain is that
for 2 and 1/2 years,

there's been no trace
of Dottie Caylor.

JULE CAYLOR: After
the first few days,

I thought that she had left
temporarily to-- well, simply

make things inconvenient for me.

I think that Dottie could
have disappeared to get even

with her husband who
had disappeared on her

for half of their married life.

She could have done
that in the beginning.

It's very hard to
imagine her doing

that for a great
long period of time.

ROBERT STACK: Immediately
after she disappeared,

Dottie's friends wondered why a
woman so afraid of the unknown

would leave behind everything
she had and everyone she knew.

At first, they thought
she may have left

to escape an unhappy
marriage and start

a new life in another city.

But as the months
and years elapsed,

there was no word from Dottie.

Holidays, birthdays, and
anniversaries went by.

Now Dottie's friends and family
are wondering could she really

have vanished voluntarily?

Or was her disappearance
more sinister?

In 1973, Dottie
married Jule Caylor,

an entomologist with the
National Forest Service.

They settled in the
Oakland suburb of Concord.

But over the years, her home
became a self-imposed prison.

JULE CAYLOR: Dottie
had what doctors

have called agoraphobia.

She would stay inside
most of the time.

She couldn't even apply for a
job, much less hold one down.

It was a real problem.

ROBERT STACK: Dottie and
Jule's marriage deteriorated.

Dottie was often home alone
because Jule was working out

of town over 50% of the time.

Then in November of
1981, the relationship

erupted in violence.

PAULA POWERS: She told me
that they got in an argument.

It escalated to the point
where he finally hit

her with a board or something.

And she received a
wound in her head.

And that she did grab
some scissors and said,

you keep away from me,
and protected herself.

And she was standing over
top of me with those scissors.

ROBERT STACK: Jule says that
Dottie started the fight.

Swearing at me and
saying I'll kill you,

you son of a-- I'll kill you.

And I grabbed her little typing
stand and hit her with it.

ROBERT STACK: Dottie needed
to pull together the threads

of her disintegrating life.

So in 1984, she
joined a support group

called "Women in Transition."

Without ever telling
Jule, she attended

meetings for over a year.

PAULA POWERS: I met
her in the fall.

And of course the last time
I saw her was in late spring.

And I thought she'd
made a tremendous amount

of progress, actually.

As time went on, I would
notice she's adding a little

more color to her outfits.

She is taking a little
more care with her hair.

She cut her hair in
a new style, which

was a very scary thing for her.

It was as if a new
Dottie were emerging.

JULE CAYLOR: She had secret
lives, a secret existence

that I knew nothing about.

And she wanted it that way.

She pursued that.

I only began to become
aware of it near the time

that she disappeared.
I wasn't even aware of it.

I was just suspicious.

ROBERT STACK: Dottie
secretly rented

a post office box
so she could receive

mail without Jule's knowledge.

She opened a
personal bank account

and transferred $5,000
into a cashier's check.

Then one month before
Dottie disappeared,

Jule told her he had to accept a
job transfer to Salt Lake City.

JULE CAYLOR: Dottie
had said in the event

that I got transferred
that she was not

interested in going with me.

So I wasn't expecting
her to go with me

and wouldn't even have
wanted her to, I guess.

ROBERT STACK: According to
Jule, on Wednesday, June 12,

Dottie set off on
an overnight trip.

He drove her to the
Pleasant Hill BART station.

JULE CAYLOR: I took her
down to the BART station.

She had with her a
little overnight bag.

Bye, Jule.

JULE CAYLOR: And
I dropped her off.

And she walked around the corner
of the station and disappeared.

ROBERT STACK: Jule is certain
that Dottie had her purse, as

well as her overnight bag, as
she walked into the station

for the last time.

But he can't be sure that
Dottie ever boarded the train.

The next day around noon, Jule
returned home early from work

and got off the train at
the Concord BART station.

In the parking lot, he was
surprised to find Dottie's

Volkswagen next to his car.

JULE CAYLOR: So I walked
over and looked inside.

And then I noticed her purse.

And that was very, very strange.

SHELLEY WILSON: She
told me how important

it was to her to have her
purse with her all the time.

She felt secure if she felt
she had a lot of her things

with her.

And she felt safe
out in the world.

That's one of the things
that made me feel so terribly

upset, when I
realized that she had

not taken her purse with her.

ROBERT STACK: Jule left
a note on Dottie's car,

asking her to contact him.

Over the next four
days, he left two

more notes, talking
about problems

he was having with the house.

He also expressed his love and
pleaded with her to come home.

SHELLEY WILSON: I spoke to Jule.

And Jule told me
that he hadn't seen

her for three or four days, and
he didn't know where she was.

And that her car was
there, her purse was there,

and he didn't know
where she was.

I was extremely upset.

I asked him if he
called the police.

And he said that he had not.

And this made me very--
just almost hysterical.

ROBERT STACK: Five days
after Dottie vanished,

Jule filed a missing
persons report with the Bay

Area Rapid Transit police.

The following day, the
Concord Police Department

was finally notified of
Dottie's disappearance.

Not by Jule, but
by the BART police.

Two weeks after Dottie vanished,
Jule moved to Salt Lake City,

where he still lives and works.

Back in Concord, Diane hired
a private investigator,

Francie Koehler.

FRANCIE KOEHLER: : The status
of the case at this point is we

view it as-- I view it as
10% missing persons case

and 90% potential foul play.

ROBERT STACK: As their attempts
to locate Dottie turned up

no new leads, Diane and
Francie started to worry

that Dottie might be dead.

They began to consider
Jule a suspect.

We don't know
for sure if Dottie

ever got to the BART station.

The only one that has reported
that Dottie went to the BART

station is her husband Jule.

We don't know if
she ever got there.

If this proves to be
anything other than a straight

disappearance case, Jule will be
a suspect in her disappearance

or in her death,
whatever it may be,

along with anybody else that
may have been close to her

at the time or prior
to her disappearance.

You would certainly consider
those around that person

as being possible suspects.

No, that doesn't
bother me at all.

I suspect that she either
willfully disappeared and then

was helped to
permanently disappear

or perhaps just got in
with the wrong person,

right at the start.

ROBERT STACK: 2 And
1/2 years have passed.

And still, no one knows
if Dottie Caylor built

a secret life for herself, to
escape an unhappy marriage,

or if she was simply
the victim of foul play.

DIANE RUSNAK: I think there's
a chance that Dottie is dead,

which is very disturbing
to think about.

I have many dreams about this.

And the authorities I
speak to and the friends

I speak to come up
with hundreds of ideas.

There's no peace.

There's no rest.

There's no conclusion.

And we won't forget her.

It was hell
living with Dottie.

It was hell having her
disappear the way that she did.

And yet, since I've gotten
here and gotten settled

and into a new job and that
whole problem is behind me,

things are really pretty good.

Tonight's mysteries are
stories without endings,

all missing that one vital clue.

Perhaps someone watching
tonight knows what happened

and can reveal the truth.

Perhaps it's you.
