JACKSONVILLE, FL (RNN) – A mass shooting at an entertainment complex in downtown Jacksonville on Sunday afternoon left two people dead, along with the suspected gunman, the Jacksonville Sheriff's Office said.
Eleven other people were injured – nine of them from gunshots.
Two victims and the suspect died at the Jacksonville Landing, the shopping and dining complex where the shooting took place, Jacksonville Sheriff Mike Williams said Sunday evening.
Williams said the suspect killed two people, and then shot himself with a handgun.
There are no other suspects, and the shooting site has been secured, according to Williams.
The sheriff identified the suspect as 24-year-old David Katz, believed to be from Baltimore, MD. Williams said investigators, including the FBI in Baltimore, are working to make final confirmation of the suspect's identity.
The Baltimore Sun reported that federal authorities were investigating a home near South Baltimore on Sunday night in connection with the shooting.
Investigators believe Katz was in Jacksonville for the Madden 19 tournament, a video game competition and that he might have stayed in town Saturday night. Authorities have also located and impounded the suspect's vehicle, Williams said.
Williams said Sunday evening that he couldn't comment on the suspect's possible motives.
Initial media reports said four people had been killed, citing law enforcement sources close to the investigation.
The shooting occurred at the Chicago Pizza restaurant at Jacksonville Landing, authorities said Sunday evening. The restaurant is next to the GLHF Game Bar, where a qualifying event for the video game tournament was taking place.
Williams said law enforcement received 911 calls shortly after 1:30 p.m., local time, about shots fired at the location, and that authorities responded within minutes.
Video feeds captured the sounds of gunfire, because the tournament was being live-streamed at the time of the shooting.
Williams is asking anyone else who may have recorded the incident to contact investigators.
Electronic Arts, the company that makes the Madden 19 game, tweeted a statement in the hours following the shooting, sending sympathies to the victims' families. They also said they were cooperating with law enforcement during the investigation.
Multiple people were transported to Jacksonville-area hospitals. Some victims transported themselves, Williams said.
CNN reports that three people are being treated at Memorial Hospital, and are in stable condition. One person was taken to Baptist Medical Center with a minor injury.
UF Health Jacksonville took in six patients, four of whom were discharged from the hospital. The two remaining victims include one in serious condition; that victim has multiple gunshot wounds to the chest, according to CNN.
Jacksonville Mayor Lenny Curry thanked law enforcement and medical personnel for their quick response to the incident, saying: "At terrible times we see the best in people, and today is no different."
Florida Governor Rick Scott met with local and state law enforcement officers and tweeted a thanks to Jacksonville Fire and Rescue, whom he credited with rushing toward the shooting in order to save lives.
