For our next story, we need to warn you--
it contains images that may be disturbing for some viewers.
The crime of this pure evil overkill.
NARRATOR: We're in Knoxville, Tennessee for the trial
of 32-year-old Joel Guy Jr. He's charged with two
counts of first degree murder in the vicious killing
and dismemberment of his own parents,
Joel Guy Sr. and his wife Lisa.
It was the Monday after Thanksgiving weekend.
Lisa Guy had not shown up for work,
and her employer made a call to police.
NARRATOR: When officers arrived, they discovered a grisly scene.
Hello!
Sheriff's office!
Police!
Sheriff's Office!
Knox County Sheriff's office!
We're here to check your welfare!
NARRATOR: Inside, police found the remains of Joel and Lisa,
who were both stabbed over 30 times and dismembered.
Their son, Joel Jr., was the first and only suspect.
He'd spent Thanksgiving with his parents,
and made charges to his father's credit card after the murders.
His parents had been supporting the 28-year-old for years,
and recently told Guy they were cutting him off financially.
Police believed Guy was angry, and hoped
to cash in on his parents' life insurance policy.
He was charged with first degree premeditated murder
and abuse of two corpses.
He pled not guilty.
At trial, the prosecutor described the viciousness
of the attacks and Guy's attempt to eliminate the evidence,
all while Guy listened to the graphic description
of the crime scene.
He covered them with a corrosive substance
and left them there to liquefy into some sort
of diabolical stew of human remains.
NARRATOR: The jury was shown surveillance footage
of the defendant with a hand wound,
buying products apparently to help dispose of the bodies.
She paid for the tubs that she and her husband
disintegrated in.
NARRATOR: And perhaps most incriminating
was Guy's notebook, which contained written excerpts
outlining his plan, including one that
read "get plastic sheeting for disposal process," and "money,
all mine, $500,000."
After hearing all the testimony and reviewing the evidence,
the jury returned with a unanimous verdict.
JUROR: We the jury find the defendant, Joel Michael Guy,
guilty of first degree premeditated
murder of Joel Guy Sr.
Count number two, please.
JUROR: We the jury find the defendant, Joel Michael Guy,
guilty of first degree premeditated
murder of Lisa Guy.
NARRATOR: Before sentencing, family members gave impact
statements about the victims, and the nightmare they
were forced to live through.
The next day after we buried Joel and Lisa, my mother died.
She truly died of a broken heart.
The impact of this crime is notorious.
We will never, ever be the same.
I am Joel and Lisa's daughter.
You'll never know what it is like to have to tell your--
your children that their grandparents
have been chopped up and put in acid.
NARRATOR: The last person to speak
was the judge, Steve Sword.
NARRATOR: Guy was sentenced to two life
sentences, plus four additional years
for his treatment of the remains.
He won't be eligible for parole until the year 2071,
when he'd be 83 years old.
