Investigators said some of the victims are not cooperating with police.

“When you don’t have cooperative witnesses it’s hard to thoroughly investigate because we need them to help us find the people responsible for the shooting to tell us what occurred,” said Lt. John Green.

At this time, investigators do not know what led up to the shooting and said there was no known altercation.
