Police are trying to determine who fatally shot Ronnie Croom Jr. and injured the four others early Tuesday at Durty Nelly's Eatery and Pub, located at 2805 N. Franklin Road on the city's east side.

"A lot of the people who were involved (and) had a vested interest in leaving left before the police got here," Indianapolis police Detective Ed Brickley said Wednesday. "The people who stuck around when the police were here were ones who were inside or employees or friends of employees who didn't see a lot that happened outside."

Police said the shooting happened during a disturbance that involved up to 30 people. Security workers were moving people into a parking lot when the gunfire started shortly before 3:30 a.m.

Croom was taken to a hospital, where he was pronounced dead. The other four wounded people are expected to survive, 6News' Rick Hightower reported.

Police said anyone with information about the shooting should call Crime Stoppers of Central Indiana at 317-262-8477.
