“We had enough probable cause for us to seek this person and for us to, in fact, (make an) arrest this morning," Tomba says. "We’ve got five individuals who are deceased. We’ve got a 9-year-old who was shot. The scene was a very, very complex one to process and we’ve got a lot of evidence to go through. So as far as who pulled the trigger, that has yet to be determined."

The man has not been charged or identified. The department has 48 hours to either bring charges or release him.
