JACKSONVILLE, Fla. -

A Mandarin man charged in the shotgun killing of his wife last year has been found not competent for prosecution and remanded to the custody of the Department of Children and Families for treatment.

Peter Jensen is accused of killing 24-year-old Karina Jensen in their home off Julington Creek Road in September.

Jacksonville police said the killing took place after Jensen had been playing violent video games.

Jensen is also facing charges he assaulted a corrections officer while in jail, as well as 34 counts of having child porn on his computer.

He has a competency review coming up next month.

Jensen claimed he had been on a two-day binge the night his wife was killed. He told detectives he was smoking bath salts and marijuana when his friend and drug dealer, "Matthew," shot his his wife in the head.

Crime scene photos revealed a collection of shotguns, handguns, a rifle, a silencer, a machete and dozens of shells and bullets.

During an interview with detectives, Jensen went on to say "Matthew" raped his wife before shifting back to the night of the shooting, where he said he and Matthew struggled over the shotgun.

According to a police report, police found Jensen naked by a shed, where he was heard shouting, "I'm not the guy you're looking for. I didn't kill my wife. It was the drug dealers."
