Deputies have not confirmed a motive for the shooting, but they said it appears that Katz targeted his victims. Witnesses told Channel 9 that Katz was upset that he had lost a match earlier in the day.
Deputies said Katz legally purchased two guns from a licensed dealer in Maryland last month and he had extra ammunition with him. One of the gun's had a laser sight on it, officials said.
