According to police, the shooting occurred at approximately 12:24 p.m. Surveillance video sent to Action News shows a man standing outside a train as two other men exit. There is a quick exchange of words between the couple and the man on the platform. Both the victim and the assailant drew guns, although no weapons were found. “There was a SEPTA worker next to us and she said there was a shooting,” said SEPTA rider Scott Clearfield of Northeast Philadelphia. The shooting caused the Clearfield train to be derailed for nearly an hour. “We were all waiting, then they passed us right past 15th Street and just said, ‘Go ahead.’ It was scary,” Clearfield said. Transit police were patrolling the station and responded immediately, investigators said. The 19-year-old victim was shot three times, in the chest, stomach and right arm. He was taken to Jefferson University Hospital in critical condition. The attacker managed to escape in the middle of a group of passengers running from the station. SEPTA police have tried to combat escalating violence on the transit system by beefing up security. “I’m thinking about driving to work instead of taking public transportation. It just doesn’t seem safe anymore,” said Clearfield. According to Action News, the 19-year-old victim who is being treated at the hospital is in custody. Police have not commented on whether or not this was due to the shooting. Anyone with more information about the shooting is asked to call police. Copyright © 2022 WPVI-TV. All rights reserved.
