Florida Madden Tournament shooter had history of mental illness, police visits to family home

JACKSONVILLE, Fla. -- (KTLA) -- David Katz, the shooter who killed two people and wounded 10 others before taking his own life at an e-sports tournament in Jacksonville, Florida, on Sunday, was in treatment for psychiatric issues at least as early as the age of 12, according to family divorce records.

Katz, who was 24, was prescribed a number of psychiatric medications, including an antipsychotic, and saw “a succession of psychiatrists,” according to a 2006 letter from the father's attorney. A separate 2006 court filing states that a therapist said David had experienced a “psychiatric crisis.”

CNN also obtained police records that show 26 calls for service to the police from the Katz family home in Columbia, Maryland, from 1993 to 2009, for issues ranging from “mental illness” to domestic disputes. At least two of those calls involved Katz arguing with his mother, though none of the reports provided to CNN show any physical violence. The Howard County Police Department declined to release the reports from a number of the incidents, citing statutory restrictions.

Since Sunday's shooting, the family has told investigators that David Katz suffered from mental health issues, according to a law enforcement source who described the family as being very cooperative with investigators. Both parents have worked for the federal government. Richard Katz is a NASA engineer employed at the Goddard Space Flight Center outside Washington, DC, according to an agency spokesperson. Elizabeth Katz was listed as an employee of the Food and Drug Administration at the time of her divorce.
