Police say it happened just before 3 a.m. on Saturday at the Scalp Ave. location.
Detectives said a man tried to rob the teenage boys and a fight broke out. The man then shot the 16-year-old boy in the leg and hit the other 18-year-old on the head.
The restaurant manager gave the man cash before he fled the scene.
WTAJ reached out to the McDonald’s–an employee said they have no comment.
Police are still searching for the suspect.
“We’re very fortunate in this case that no one died and we’re very fortunate in the fact that nobody else got shot or injured,” said Richland Twp. Police Detective Kevin Gaudlip.
Initially, investigators believed the suspect was driving a dark blue or black car with a dent on the door of the driver’s side. Police no longer believe that car is related to this incident.
Anyone with information is asked to contact Richland Township Police: 814-472-2100.
