Police identified the gunman as Ian David Long, a 28-year-old former Marine. Officials believe he died by suicide. It's unclear how many Long wounded in the attack, but the Ventura County Sheriff’s Office said about 22 people had been transported to hospitals in the area. According to the Daily Beast, some of the patrons were survivors of the mass shooting at a country music festival in Las Vegas that left 58 people dead in October 2017.

"Ron was a hardworking, dedicated sheriff’s sergeant. He went in to save lives, to save other people," Ventura County Sheriff Geoff Dean told reporters on Thursday. "He was totally committed, he gave his all. And tonight, as I told his wife, he died a hero."
Sgt. Helus is survived by his wife and son. According to Dean, he called his wife shortly before arriving at the scene. He reportedly told her: "Hey, I gotta go handle a call. I love you. I’ll talk to you later."
Coffman was a 22-year-old umpire for a youth baseball league and planned to enlist in the Army, his father Jason Coffman told reporters. He is survived by his father, mother, and three younger brothers. A little sister was on the way.
"I talked to him last night before he headed out the door," Jason Coffman said of his last exchange with his first-born son. "First thing I said was, 'Please don’t drink and drive.' The last thing I said was, 'Son, I love you.'" He added: "This is going to be an absolute heartwrenching time for me and my family. This is a heart that I’ll never get back."
