A teen accused of killing his girlfriend in a Skippack park will stand trial on September 29th.
Tristan Stahley, now 18 years old, is charged with murder in the death of Julianne Siller, who was 17 years old at the time of her death. Police say, Stahley took Siller’s life on the night of May 25th of last year. Reports indicate that Stahley’s attorney will try to use the defense of diminished capacity for Stahley’s actions. Stahley is being held without bail at the Montgomery County Correctional Facility until next month’s court date.
