Narrator: when bobby curley
Was brought to the hospital
Hallucinating and in extreme
Pain, doctors could not find the
Cause.
At first, they diagnosed a
Neurological problem, but his
Condition deteriorated.
Something he was given in the
Hospital wasn't curing him.
It was k*lling him.
Young man with a ready smile,
Many good friends, and a loving
Family.
My brother bobby, he was a
Fun-loving guy.
He really was.
He cared for his family very
Much -- myself and his mom and
My other brother, dave.
He was just an all-around great
Guy.
Bobby was a perfect brother,
A great brother.
We fished together a lot.
We'd go to canada twice a year
Fishing, and we'd have a ball up
There.
Narrator: in august of 1990,
Bobby married joann chopak, a
Young widow with a 4-year-old
Daughter.
Bobby and joann had been dating
For about a year following the
Death of joann's first husband
In an automobile accident.
I gave them my blessings.
I said it was time for him to
Get married and have a life of
His own.
They had a beautiful wedding.
Bob really wanted to meet a nice
Girl and start a family and just
Enjoy life.
And he said he really loved her.
And I was very happy for bob.
Narrator: the couple moved
Into joann's home on a quiet
Street in
Wilkes-barre, pennsylvania.
Bobby worked for the
Morgan corporation as an
Electrician.
And in may of 1991, he and his
Crew started work on a major
Renovation project in a local
Chemistry lab.
We'd go in, and supposedly,
We were told that everything
Would be cleared out of the
Labs, there would be nothing in
There.
Well, we'd go in a lab, and
There'd be bottles of chemicals
Here, stuff over there spilled,
And that.
And it was kind of, you know, I
Thought hazardous.
Narrator: three months into
The project, bobby became ill.
His brother noticed something
Was wrong when they met at a
Local bar one day after work.
After one beer, he was ready
To leave, and I asked him why.
And he said he just didn't feel
Right.
His feet were burning for some
Reason and his feet hurt, and he
Had a hard time walking.
And I didn't know what was the
Problem.
Narrator: bobby also
Complained of numbness in his
Hands and pain in his feet.
When he went to the local
Hospital, doctors diagnosed his
Illness as guillain-barré
Syndrome, a rare condition that
Causes numbness and weakness of
The extremities.
Although it can be serious, most
Patients recover.
Bobby's condition gradually
Improved, and he was released
From the hospital.
But the pain returned, this time
Even worse than before.
He was also vomiting.
He couldn't even stand up.
And he had to go to the
Bathroom, and I remember my
Sister and I had to literally
Carry him to the bathroom.
Once we got him into the
Bathroom, he looked at me, and
He said, "sue, please call the
Ambulance."
He knew he was that sick.
Narrator: this time, curley
Was taken to a regional medical
Center about 100 miles away.
When he got there, he was
Hallucinating and had to be
Restrained.
I thought maybe at one point
That he would get better, but he
Never did.
He got worse and worse.
He couldn't sit.
He couldn't lay.
Everything was bothering him.
Narrator: although curley's
Blood tests were all normal,
Dr. Donovan had a hunch.
And if he was correct,
Bobby curley was dying.
Narrator: when bobby curley
Was examined by doctors in the
Regional medical center, his
Blood tests were all normal.
But his doctors noticed
Something that had previously
Been overlooked -- bobby curley
Was losing his hair.
He had had weakness and
Numbness in the extremities.
And he particularly had had
Burning and pain on the soles of
His feet, which is a classical
Description of arsenic and
Thallium poisoning.
That coupled with the hair loss
Almost makes the diagnosis.
Narrator: a special urine
Test confirmed dr. Donovan's
Suspicion.
Curley was suffering from
Thallium poisoning.
Thallium is a rare and highly
Toxic poison which doesn't show
Up in routine lab tests.
Before it was banned in the
United states in the early '70s,
Thallium was commonly used in
Rat poison.
It can take months to build up
In the body before causing
Symptoms.
Unfortunately there is no known
Antidote for thallium poisoning.
Well, my first thought was,
"Could I save this patient?"
Unfortunately by the time I was
Involved in this case and the
Diagnosis was being established,
There was very little that can
Be done.
And I remember him pointing
To all his diplomas and
Everything else, his
Certificates on his walls, and
Saying, "all of these can't do
Anything for your brother."
He said, "there is just nothing
That we can do.
Your brother is going to die."
Narrator: on september 26th,
Bobby curley lapsed into a coma.
When there were no longer any
Signs of brain activity, he was
Taken off life support.
We said our goodbyes to
Bobby, and we went.
And I couldn't see bobby going.
I couldn't.
It wasn't easy.
I talked to him.
Who knows, maybe he did hear.
We don't know.
But it wasn't good.
It wasn't fun.
Narrator: the autopsy
Confirmed that curley died of
Complications caused by thallium
Poisoning, most likely one large
Dose.
Hospital officials notified the
Occupational safety and health
Administration to see if curley
Could have ingested the thallium
While working at the chemistry
Lab.
One of curley's co-workers
Believed the work site was
Unsafe.
In one lab I found a wiping
Rag.
It had a note put on it,
"Thallium wiping rag.
Touch me and die."
And I remembered -- this was
After bobby was already sick --
And I remember going and telling
Joey and the other guys that,
"Don't go in that room and work.
There's thallium and it's heavy
Metal.
It's a poison.
I don't think we should be going
In there."
Thallium can be ingested, it
Can be absorbed through the
Skin, or it can be inhaled.
So any one of those roots could
Give you a poisoning-type
Exposure.
Narrator: to find out if
Thallium could have been
Accidently ingested by workers
In the lab, air samples were
Collected, counter and shelf
Surfaces were swabbed, and dust
And dirt samples were all taken
For analysis.
Joann curley told investigators
That her husband had brought
Home some cabinets from the
Laboratory which were going to
Be discarded.
The cabinets were also tested
For thallium.
The results of all of these
Tests were negative, and none of
The other electricians who
Worked with bobby curley at the
Chemistry lab had thallium in
Their systems.
Joann curley requested a
Thallium test for herself.
Both joann and her 4-year-old
Daughter, angela, tested
Positive for thallium.
It was not enough to either
Cause symptoms or even to need
Treatment, but it did indicate
That there had been abnormal
Exposure to thallium for both of
Them.
Narrator: investigators found
Traces of thallium in curley's
Home.
They found it in two thermoses
Bobby took with him to work
Every day, thermoses that
Usually held iced tea.
I did not know who placed the
Thallium in the iced-tea
Containers.
I cannot confirm that, but I
Think that somebody certainly
Did, and that caused his death.
And homicide is one person
Causing the death of another.
Narrator: police turned their
Attention to bobby curley's
Co-workers and the possibility
Of a practical joke gone bad.
Narrator: when traces of
Thallium were found in a thermos
Bobby curley took to work,
Police questioned his
Co-workers.
They'd ask me how well he got
Along with the other guys on a
Job, was there any bad blood,
Did he have any arguments, stuff
Like that.
Narrator: bobby curley was
Only 32-years-old when he was
Named foreman of the electrical
Job at the chemistry lab.
His promotion bypassed several
Older, more experienced
Electricians.
Was jealousy a possible motive?
Investigators also discovered
That curley was sometimes the
Victim of practical jokes.
Co-workers would sometimes lace
His food with seasonings as a
Joke.
Curley was just one of
Several people that had jokes
Played on him.
But it would be like hot pepper
And chewing tobacco or things of
That nature.
And it was theorized that
Possibly somebody put the
Thallium in his iced tea,
Mistaking it for valium, just to
See what it would do to him.
Narrator: when investigators
Looked closer at the thermoses
In curley's home, they found
Thallium in the threads of a
Pint-sized thermos that bobby
Never took to work.
Joann curley offered an
Explanation.
She recalled that once, after
Her husband came home from work,
She poured some leftover iced
Tea from his work thermos into
The smaller, pint-sized one so
It wouldn't go to waste.
Joann said that she and her
Daughter may have consumed some
Of that iced tea later, which
Would explain how they had
Thallium in their systems.
Bobby curley's family grew
Increasingly suspicious of
Joann's possible involvement in
Bobby's death, especially after
Thallium was found in bobby's
Thermos.
Curley's family asked
Authorities if there was any way
To prove whether joann was
Involved.
To find out, the district
Attorney had curley's body
Exhumed for a second autopsy.
Forensic toxicologist
Dr. Fredric rieders was
Particularly interested in
Analyzing bobby curley's hair.
When a substance like thallium
Is circulating in the
Bloodstream, it will attach to
The hair root, which is a cell.
Thallium then stays on the hair
Shaft, even as the hair grows
Out.
Hair grows at the average rate
Of 1.3 centimeters per month,
Which means that a strand of
Hair can contain six months or
More of medical history.
Dr. Rieders took samples of
Bobby curley's hair and cut them
Into smaller pieces, a process
Called segmental analysis of the
Hair samples.
Those segments were then
Analyzed with a test called
Atomic absorption
Spectrophotometry, which shows
Which sections of hair contained
Thallium and which sections did
Not.
The results were plotted on a
Calendar and indicated that
Bobby curley was exposed to
Thallium long before he started
Work in the chemistry lab.
Curley received a dose of
Thallium -- not a very large
One -- essentially two months
After they got married, about a
Year before he died.
Narrator: forensic tests
Would soon provide police with
Even more shocking evidence,
Evidence that pointed in only
One direction.
Narrator: segmental hair
Analysis indicated bobby curley
Had been systematically poisoned
With thallium for almost a year,
Long before he started work in
The chemistry lab.
And the tests also indicated
Bobby had ingested a massive
Dose of thallium as he lay dying
In the hospital.
This horrifying scenario was
Confirmed when dr. Rieders
Discovered a large concentration
Of thallium in bobby curley's
Intestines.
He got a very large dose not
Too long before he died.
The concentrations in the
Intestine were 1,000 times
Higher than the concentrations
In his blood and in his autopsy
Tissues, which meant that they
Were of very recent origin.
Narrator: using the timeline
Of ingestion, investigators
Eliminated individuals who had
No contact with bobby curley
During the times he had been
Poisoned.
This was an investigation of
Exclusion -- eliminating people
That could not have done it
Until you got down to the one
Person left that had to have
Done it, which was joann.
Narrator: police also learned
That joann and bobby were not
Always a happy couple.
At first, I do think bob was
Very happy, but then -- even
Just a few months into the
Marriage, I wasn't quite sure.
Bob made some different comments
Maybe that he wished he never
Got married.
Narrator: police discovered
That shortly after the wedding,
Bobby made joann the sole
Beneficiary of his
Life-insurance policies worth
Nearly $300,000.
Forensic tests showed that the
Poisonings began approximately
Two months after bobby and joann
Married.
That was a shocker.
I couldn't believe that.
It's like she planned it right
From day one.
When the papers were signed
Making her beneficiary of
Everything, that's when she
Started.
Narrator: family members
Recall joann's disturbing
Behavior the moment bobby was
Taken off life support.
I remember none of us could
Go into the room and stay there
And watch this happen, but joann
Could.
She wanted to stay in the room
And...
See bob die.
Narrator: on december 12,
And charged with first-degree
m*rder.
Facing overwhelming forensic
Evidence and the possibility of
The death penalty, she pled
Guilty to a lesser charge of
Third-degree m*rder.
At her sentencing, joann
Publicly admitted what forensic
Testing had already confirmed --
That she had systematically
Poisoned her husband with
Thallium.
Today joann curley is a
Confessed k*ller.
Today joann curley surrendered.
In open court and under oath,
Joann curley admitted that she
Personally poisoned her husband
Over a lengthy period.
She openly admitted to how it
Was done, when it was done, and
To the type of poison used.
Narrator: she placed the
Thallium in her husband's iced
Tea about a dozen times.
Her confession matched almost
Perfectly dr. Rieders' timeline.
And that her confession
Paralleled it, frankly, I was
Amazed.
I wasn't proud or delighted.
I mean, it was good.
But I was amazed.
Narrator: joann's confession
Told a horrific tale of m*rder
Motivated by greed.
Her answer when asked
Point-blank why she did this
Was, "for the money.
I k*lled him for the money."
Narrator: joann said she used
Rat poison she found in her
Grandmother's basement.
At first, she used only a small
Amount in her husband's iced
Tea, but later increased the
Amount when she feared it wasn't
Working.
Okay, here's your tea.
Oh, thanks, hon.
Have a good day.
You too.
Narrator: in the hospital,
Joann finished what she started.
She poured a massive amount of
Thallium into his soda and gave
It to him as he lay dying.
Honey, wake up.
I brought you something cold to
Drink.
Thanks.
That's unbelievable -- to be
Married two months and start
k*lling your husband.
And the last one, that's the
One that really bothered me --
That he got it while he was in
The hospital, 'cause I was there
That day, and joann was there.
And I was sitting next to her,
And her purse was right there
Between us.
And to know now that the
Thallium was in her purse at
That time is really -- that
Bothered me.
That really bothered me.
Narrator: tests revealed that
Joann and her daughter ingested
Minute traces of thallium
Sometime after bobby's death.
Joann may have ingested the
Thallium intentionally and given
A small amount to her daughter
In order to divert police
Suspicion.
Joann curley denies this and
Says she has no idea how she and
Her daughter ingested the trace
Amounts of thallium.
Ironically joann curley was not
Aware that thallium was present
In the chemistry lab where bobby
Was working before his death.
Her not knowing what the
Chemical was that she was
Poisoning him with and then to
Have found it at the university
Where he last worked, you
Couldn't ask for a bigger
Coincidence when you were
Sitting there as joann curley.
Narrator: but forensic
Science had established a
Toxicological timeline of a
Blushing bride's evil plan.
Joann curley was sentenced to 10
To 20 years in state prison.
Well, obviously she was
Somebody who was intent upon
Carrying out her plan.
She was intent on a result, and
The result that she wanted was
Bob curley's death.
And it was obviously a ghoulish
Type of a crime that you don't
See very often anywhere in this
Country.
I could never forgive joann
For what she did to bob.
To watch him die like that...
It was heartbreaking for me to
Watch him die, any human being
To die like that.
No one deserves to die like
That.
I know there's evil out
There, but that's the first time
I ever ran into anybody that
Could methodically poison
Somebody and watch them die.
She's a monster -- that's
What she is.
I'll always believe that.
In my heart, she took somebody
Away from us that was very dear
To us.
And we miss him terribly.
I couldn't believe that they
Got so much from so little.
From a few strands of hair, they
Were able to tell when she gave
Him the poison, how often she
Gave him the poison, and
Basically in how big of doses
She gave him the poison, right
Up to the last day.
It's amazing.
