Court Hearing for Teen Charged in Girlfriend's Murder

Investigators say 17-year-old Tristan Stahley stabbed his girlfriend to death during a break-up

A teenager who confessed to murdering his girlfriend during a break-up waived his preliminary hearing today.

Pennsylvania State Police say 16-year-old Tristan Stahley stabbed 17-year-old Julianne Siller on a hiking trail in Skippack Township's Palmer Park, Montgomery County.

Investigators say the couple, who had been dating for 9 months, was walking along the trail when they got into an argument over Siller "going out too much" and she allegedly smashed his cell phone.

Police say that Stahley admitted he stabbed his girlfriend several times, then dragged her body into a wooded section of the park.

After the teen arrived home, police say his mother, Heather Stahley, says it appeared her son had been crying and had blood and dirt on his legs.

Police say Stahley confessed the murder to his mom and his parents then notified police.

"This whole incident is just a tragic case," said Montgomery County First Assistant District Attorney Kevin Steele. "You have a young woman whose life was taken from her and a 16-year-old who faces potential life in prison for his actions."

Stahley is charged with first degree murder, third degree murder and possession of a weapon.
