4:32 PM PT -- The Jacksonville Sheriff's Office just said there were 14 total victims and 3 people who were killed, one of them being the suspected shooter ... 24-year-old David Katz of Maryland, who killed himself. Cops say he used one handgun that they know of. Katz was indeed part of the competition, having gone by usernames like RavensChamp and Bread. Announcers from a previous 'Madden' tournament noted him as elusive -- "a man of business" who "keeps to himself."
Yeah he's not here to make friends he is here to kill the competition.
