The man responsible for carrying out the shooting at a Madden NFL 19 tournament at the Jacksonville Landing Marketplace in Jacksonville, Florida over the weekend has been identified as David Katz, 24, of Baltimore.
Katz killed two people and himself, wounding several others in the process at the popular gaming tournament, where he was registered to play.
Katz was a competitive gamer who went by the nickname Bread and won the Madden NFL 17 Bills Championship tournament. He was described by fellow gamers and commentators as a "man of business" and a guy that "keeps to himself."
"David Katz is not here for the experience. ... He's not here to make friends. He's all business, he's focused. To even get him to open up to you to talk about anything is like pulling teeth."
According to court records, Katz has a history of mental illness. He was hospitalized in psychiatric facilities twice as a teenager where he was prescribed anti-psychotic and anti-depressant medications. His parents reportedly had a difficult marriage and he struggled after their divorce in 2007.
Katz allegedly obtained the semi-automatic gun he used in Sunday's shooting legally from a licensed dealer in Baltimore.
Federal agents raided the Katz's Baltimore home and the family is cooperating with the investigation.
