Teen Fatally Stabs Girlfriend On Hiking Trail, Hides Body

A 16-year-old boy is accused of stabbing his 17-year-old girlfriend along a Pennsylvania hiking trail.

Tristan Stahley and Julianne Siller left Stahley’s Skippack Township home around 8:30 pm and headed to Palmer Park along Creamery Road. While walking along a nearby trail, the young couple got into an argument over Siller “going out too much.” Siller smashed Stahley’s phone, and he then pulled out an orange folding knife and stabbed Siller in the throat and body. Stahley then dragged her body off the trail and into the woods.

Stahley returned home after the murder, and his mother, Heather, said it looked like he had been crying and had dirt and blood on his legs. When she asked her son what was wrong, he wouldn’t say. He only told her that he and Siller had gone for a walk.

After leaving the house for a walk along a nearby trail, Tristan Stahley confessed that he had killed his girlfriend. His mother asked if he was joking, and when he said no, he began crying hysterically. He told his mother that he and Siller had broken up when he stabbed her, and that he was going to kill himself because he couldn’t go to jail. Heather Stahley called the police when she and her son returned home. The teenager waited outside, and when his father, Brian, came outside, the 16-year-old was holding a knife to his neck.

Brian Stahley got into a struggle with his son before finally getting the knife away from him. He sustained scratches to the face and a bite on the hand in the scuffle, police said. Minutes later, the teen was arrested.

Troopers found Julianne Siller’s body shortly afterward by following a trail of blood. They also found the knife Stahley used to stab her.

“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 and Siller dated on and off for nine months. Friends said Siller stuck it out with Stahley because she was trying to “fix” him. He was a recovering drug addict and was taking medication for depression. Stahley is being held without bail and is charged with first-degree murder, third-degree murder, and possession of a weapon.

Julianne Siller would have graduated from Spring Ford High School in Royersford, Pennsylvania, on June 12.
