A 20-year-old Pennsylvania man has been charged for the brutal slaying of his 14-year-old cousin, who died days after being stabbed more than 80 times and shot in the head.
Colin Haag III is facing a criminal homicide charge in connection with the death of cousin Autumn Bartle, according to Bucks County District Attorney Matthew Weintraub.
Autumn died from her injuries on April 2, three days after her mother found her unconscious and bleeding in the living room of the family’s home in Bristol Township. The girl was suffering from dozens of stab wounds and a gunshot to her left temple, authorities say.
Investigators believe Autumn was attacked in a bathroom in the home, leaving it covered in blood and handprints.
It was “apparent that Autumn Bartle, with bloodied hands, had attempted to climb out of the window and escape, but was unsuccessful,” states a probable cause affidavit in the cause, which was obtained by PEOPLE.
Haag, Autumn’s cousin, was living with her family at the time but wasn’t home when Autumn’s body was discovered. He was arrested Wednesday in nearby Bensalem Township after his description was circulated statewide.
Police say ballistics evidence allegedly connects him to the crime, according to the probable cause affidavit. What’s more, authorities claim they recovered Autumn’s blood from a notebook in Haag’s backpack when he was taken into custody.
