BREAKING: Police ID gunman in fatal Jacksonville mass shooting

Sheriff Mike Williams provided additional details hours after a gunman opened fire at a Jacksonville, Florida, mall on Sunday. The incident occurred during a video gaming tournament.

According to a news update that evening, he said the gunman, who reportedly killed himself after shooting multiple individuals, had been identified pending final confirmation from the FBI.

Williams said he is believed to be 24-year-old David Katz, a gamer whose name had circulated online as the gunman prior to the official update from law enforcement.

Reports indicate he was known by his handle, “Bread,” in the gaming community.

Williams said the shooter is believed to have used a handgun, noting that the Bureau of Alcohol, Tobacco, Firearms and Explosives
will provide confirmation. He did not elaborate on a possible motive for the shooting.

The sheriff did offer some additional information about the victims.

As CrimeOnline previously reported, authorities had warned against accepting initial media reports at face value.

He said three victims — including the suspected shooter — were found dead at the scene.

Nine other victims were transported to area hospitals with varying degrees of injury. Seven had been shot, Williams said.

Two additional gunshot victims drove themselves to the hospital.

Williams said the casualty count could rise as additional victims are identified, urging anyone who was hurt in the shooting to contact authorities if they had not already.

Authorities also impounded the suspect’s vehicle, according to the sheriff’s statement. The Baltimore, Maryland, resident is believed to have arrived in Jacksonville on Saturday and spent the night in an area hotel.
