There was just a news conference, but there wasn't really a lot of information to give. The police would not give a casualty figure, except to say that "a number" of people had been killed, and one of them was a police officer.
Separate reports said that two additional officers had been "injured"; but the police commander at the news conference stated that the only known person (so far) to have "serious injuries" is the person-of-interest. Many cameras captured a man in handcuffs being led from the store, apparently wearing only boxer shorts, who was limping and seemed to be bleeding seriously from his right leg.
