Bucks County man who shot self in neck charged in cousin's murder

A 20-year-old Bucks County man has been charged in connection with his teenage cousin's death after police say the victim was stabbed and shot multiple times last week.

Authorities have charged Colin Haag with criminal homicide in the death of 14-year-old Autumn Bartle. Earlier this week, Haag had been charged with stealing two guns from the Bartle family home where he lived with Autumn and her parents.

Bartle's parents found her suffering from multiple stab and gunshot wounds at their home on the 400 block of Sycamore Avenue around 6:30 p.m. on Friday. She was taken to St. Christopher's Hospital where she succumbed to her injuries on Monday.

Following the incident, Haag, who had been living with the Bartle family, was found by Bensalem Police along State Road. Haag was found suffering from a self-inflicted gunshot wound to the neck, and officers found he was in possession of two handguns that were reported stolen from the Bartle home.

Authorities say Haag was found with a backpack that contained at least one of the stolen guns, as well as a spiral notebook that had writing and smeared blood on one of the last pages. The note read, "This the last of Slim. That's all you get, and it's the end for me." The District Attorney's office said the blood smear was Autumn's blood.

Haag has also been charged with kidnapping, unlawful restraint, aggravated assault, burglary, receiving stolen property and related charges.

Haag was treated for his injuries at Jefferson Hospital and was charged with stealing the guns following his release from the hospital.

No bail was set.
