A pizza delivery driver was shot during a robbery early Sunday morning on the city's north side.John Cookenaur, 48, was struck in the upper-left arm and was released from Wishard Memorial Hospital later Sunday, 6News' Sarah Cornell reported.Cookenaur has worked at a Domino's pizza shop on 38th Street for just a few months. He was making a stop in the 4200 block of Hillside Avenue when the incident happened.Police said Cookenaur struggled with at least four men before he was shot. After the shooting, he went to a BP gas station on Keystone Avenue, where he called police."There were two individuals with a handgun, and while the robbery was taking place, several other individuals approached and assisted, wearing ski masks," said Indianapolis police Sgt. Paul Thompson.Tyrone Whitlock, a shift manager at a Papa John's pizza shop near the Indiana University Purdue University-Indianapolis campus, said delivery driver robberies are relatively rare, but recalled one incident."They took some personal belongings, but he was safe because he didn't have a lot of cash on him," Whitlock said.Whitlock said Papa John's drivers never have much cash. Between deliveries, they drop money in lockboxes so they are never carrying more than $20.Thompson said robberies of pizza delivery drivers are far too common in Indianapolis."Typically, they don't get a lot of money, but it's a quick robbery for them," Thompson said. "It only takes a matter of minutes and they are out of the neighborhood before the police can even arrive."Because the robbery happened at night, Cookenaur couldn't give police a good description of the robbers.
