A 19-year-old man was shot Wednesday about 12:45 a.m. in a gas station parking lot at 34th Street and Keystone Avenue. Tracy Hollowell, who suffered a non-fatal injury to his side, told Indianapolis police he was shot during a carjacking, but a witness said Hollowell exchanged gunfire with another man after an argument. The man then drove off in Hollowell’s red pickup. Police recovered shell casings from two different guns and a stolen firearm that Hollowell admitted throwing behind a dumpster at the scene. Police tried apprehending the pickup driver a few blocks away, but he escaped on foot, leaving his gun and some stolen property behind.
