Sunungura Rusununguko, 29, turned himself in to police Friday evening and was held on a charge of murder in connection with the early Tuesday shooting of Ronnie Croom Jr. at Durty Nelly's Eatery and Pub.

Four other people also were shot outside the pub but survived. Police didn't say whether Rusununguko is a suspect in the wounding of those four.

Police said the shooting happened after a disturbance involving up to 30 people began at a party thrown by a promotion company at the pub shortly before 3:30 a.m.

Authorities said they believe security guards working on behalf of the promotion company began ushering people outside after the disturbance began. Croom, who was one of the promotion company's guards, and four other people were shot outside the pub, police said.

Witnesses told investigators they saw Rusununguko -- a security guard working on behalf of the pub, not the promotion company -- firing the shots that killed Croom, authorities said. It wasn't clear whether police believe there was more than one gunman.

Police say the shooting happened early Tuesday morning as security workers were ushering people involved in a fight from the bar to the parking lot.

Surveillance video at the bar supports investigators' suspicion that Rusununguko was involved in the shooting, Indianapolis police Sgt. Paul Thompson said. Police did not release the video to the news media.

"About 24 hours or so after the initial investigation started, a detective was able to develop a suspect," Thompson said. "That's been supported by video they recovered from the bar."

Rusununguko is a former professional arena football player and played collegiate ball at Ball State University.

He played for the Indiana Firebirds, as well as for teams in Colorado and New Orleans.

Police said they still are investigating the shooting. They said anyone with information about the incident should call Crime Stoppers of Central Indiana at 317-262-8477.
