The report also should determine the youth's "amenability to treatment in a juvenile facility," Walsh said.
The teenager was scheduled for a hearing Monday on the request to transfer his case into juvenile court. That hearing will be rescheduled after the evaluation is completed.
He has been free on $10,000 bail since being charged with one count of aggravated assault in the Jan. 17 shooting of a 61-year-old man at Keystone Car Wash at 215 Brumbaugh Ave., according to court records.
Roy Shields was shot in the back as he was backing his Jeep Grand Cherokee out of a bay after he washed the vehicle at around 4:20 p.m., witnesses said.
Shields was treated at York (Pa.) Hospital for a gunshot wound.
While police were responding to the report of shots fired, the teen contacted Franklin County Emergency Services and said he had accidentally discharged a rifle from inside his residence and struck a car at the car wash, according to court records filed with District Justice Gary Carter.
Witnesses heard a gunshot and saw Shields fall from the driver's side of his Jeep. They removed him from the pavement and placed him in the back of the vehicle to await medical personnel, court records show.
