Collin Griffith previously killed his father in self-defense.

In September, Catherine Griffith died from a stab wound, and her son called 911 saying she had fell on a knife.

The state prosecutor dismissed the claim that Catherine’s son painted a false picture of his mother lunging at him with a knife and accidentally falling on it. “He has painted a picture that his mom lunged at him with a knife, tripped, and somehow fell on the knife. That’s preposterous,” said the state prosecutor.

Prior to moving in with his mother, Griffith had also killed his father in Oklahoma, which was ruled as self-defense.

Collin’s grandfather also spoke about a concerning conversation he had with Collin just months before Catherine’s death.

During the court proceedings, Catherine’s father, Robert Walantas, testified about a disturbing statement made by Catherine’s son. “He said ‘my mom, I keep thinking over and over I want to slit her throat, I want her to bleed out, I want to smell the blood’,” testified Robert Walantas.

The teen’s defense team told the jury he acted in self-defense the day his mother died, and told the jury that Catherine committed “suicide by son”.

The teen’s grandmother confirmed that Catherine had numerous suicidal attempts.

The court was shown Ring camera footage that captured Catherine’s journey from Port Charlotte to Auberndale on the day of her death. She made this trip out of fear that her son would violate the court orders that were in place at the time.

The defense argued that Collin made it known multiple times that he will defend himself if his mother attacks him.

“He’s telling people ‘I don’t feel safe, I don’t want to go back with my mom’ and they kept making him do that,” Defense Attorney Amy Porinchak Thornhill said.

After less than 12 hours of deliberation Collin Griffith was found not guilty by the jury, on both the murder and kidnapping charges.

Friends of the family said they are unsure of where he will live once he is released.
