Records show Gary police responded at 2:38 a.m. Sunday to the area of the Hustle and Joe's nightclub in the 1700 block of Grant Street for multiple gunshot victims. Gary police on Monday referred questions about the case to the Sheriff's Department, which first confirmed late Monday afternoon that two Gary officers were involved.

Although 48 hours have passed since the shootout, sheriff's investigators have not yet had a chance to interview the Gary officers involved, Back said Tuesday.

"Unfortunately, until those interviews have occurred, our department cannot officially confirm whether the Gary officers fired their weapons during the incident," Back said. "We understand that the public wants that information, and we are working to provide it as soon as possible."

He said sheriff's investigators hope to conduct interviews with Gary officers as soon as possible. Neither Gary officer was injured in the shooting, he said.

Both of the Gary officers were on duty, in uniform and on patrol, Back said.

"They did take blood tests immediately after the incident, which will be submitted to our department for review," he said. "At this time we have no reason to believe they were doing anything but their duty."
