A 20-year-old man has been identified as a suspect in the slaying of his 14-year-old cousin in the Bucks County home where they lived.

Colin Haag has not been charged in connection with the girl's death, but is being held on charges of stealing two handguns from the girl's father, the Bucks County District Attorney's Office said Tuesday.

Haag had lived with the victim, Autumn Bartle, and her parents in the Bristol Township home where she was found shot and stabbed on Friday, officials said. She died from her wounds Monday morning.

Haag was arrested Monday afternoon, after he was released from Thomas Jefferson University Hospital, where he had been treated for a self-inflicted gunshot wound to the throat, authorities said.

The wounded Haag was found on State Road in Bensalem about 3½ hours after Bartle's parents discovered her wounded in the house, authorities said. Haag was carrying a .380-caliber Smith & Wesson Bodyguard pistol and a 9mm Smith & Wesson M&P pistol at the time, officials said.

The District Attorney's Office said the weapons belonged to Bartle's father, Joseph, and had been stored in an upstairs bedroom of the home in Croydon.

Officials have not disclosed a motive in the slaying.

A preliminary hearing has been set for next Wednesday on the weapons-theft charge.
