Authorities brought in a mental health specialist who concluded that Long could not be involuntarily committed for psychiatric observation but anxious the 28-year-old Marine veteran might have post-traumatic stress disorder.
Ventura County Sheriff Geoff Dean said that after the shooting had stopped, Long was found dead in a back room in the bar.
The sheriff said Long drove to the bar and shot an unarmed security guard who was standing outside before opening fire at random inside.
Sheriff's Capt. Garo Kuredjian said investigators were still interviewing witnesses, have served a search warrant at Long's home and searched the auto Long drove to the bar.
Orfanos' father, Marc Orfanos, told the Ventura County Star: "It is particularly ironic that after surviving the worst mass shooting in modern history, he went on to be killed in his hometown".
"Please continue to keep Sergeant Helus' family, friends and coworkers in your thoughts and prayers during this hard time", Kuredjian said. Kelly said he'll be looking to God for comfort in the coming weeks and months.
Our sources say investigators discovered the messages on Long's page several hours after the shooting and contacted Instagram to delete his page.
Authorities haven't named all the victims of the attack.
