Oklahoma 'psychopath' teen facing charges for killing his mother one year after shooting dad dead

An Oklahoma teen is facing charges for killing his mother after charges were dropped in his father’s murder.

Collin Griffith, 17, was arrested Wednesday for stabbing his mother Catherine to death in his grandmother’s Florida home on Sept. 8. He is charged with first degree murder .

As police investigated Catherine’s death, they uncovered a shocking revelation. The teen had murder his father just the year before.

Polk County, Florida, Sheriff Grady Judd said during a news conference: “As we begin to pull back the layers of this onion, we find out that this is not just a singular event.”

In February of last year, he shot his father Charles outside their home in Stroud, Oklahoma. Collin said at the time that his dad pulled a knife on him, so he shot him once in the chest and once in the head.

In that case, Lincoln County District Attorney dropped the charges less than a month later as self defense could not be ruled out.

Sheriff Judd is now wondering why the teen was able to travel across state lines from Oklahoma to Florida just a month after the incident.

Judd said: “When I look at him, I see a psychopath. He’s violent. He’s dangerous. He showed zero remorse.”

On Sept. 8, police received a 9-1-1 call from Collin saying he and his mother had a long fight, during which she fell on a knife. She was bleeding from the neck and died from her injuries.

The medical examiner, after looking at the body, said it is not reasonable or plausible that she died the way he said she did.

Neighbors also had a different story from Collin. They revealed they saw the teen arguing with his mother, then dragging her in the house.

“They actually saw Collin drag his mother into the house by the hair on her head,” Judd said.

Prior to his mother’s death, Collin had made threats in the past that he would kill himself and his mother. He was also arrested for domestic violence against his mother after she disciplined him by taking his video game privileges away.

Judd said: “When you look at this and you see how violent and how dangerous he is, it makes you wonder to what extent and what depth of investigation was done, because they released him from that murder charge that was lodged apparently within a month or so.”

Sheriff Judd has contacted Lincoln County District Attorney's Office regarding Collin’s previous murder case.

“And they said if we develop information during this investigation that allows them, they will reopen the murder investigation in Oklahoma and potentially charge him out there,” Judd said.
