A gunman walked into Borderline Bar and Grill in Thousand Oaks, Calif. on Wednesday. He set off smoke bombs in order to create confusion before shooting a security guard at the entrance and opening fire into the crowd.

Authorities identified the gunman as Ian Long, 28, of Newbury Park, Calif. Long was found dead at the scene after killing 12 and wounding about 15 people.

Long was a Marine Corps veteran who had served in Afghanistan, and while investigators say there was no clear motive, he had apparently been struggling with mental health issues.

The shooting was the nation’s deadliest attack since Parkland, Fla. in February.

Among those who died was Sgt. Ron Helus, who was only one year from retirement. Another was Cody Coffman, 22, who planned to join the Army. Aliana Housley, 18, was a student at Pepperdine University.

In response to the shooting, President Trump tweeted, “I have been fully briefed on the terrible shooting in California. Law Enforcement and First Responders, together with the FBI, are on scene. 13 people, at this time, have been reported dead. Likewise, the shooter is dead, along with the first police officer to enter the bar. Great bravery shown by police. California Highway Patrol was on scene within 3 minutes, with first officer to enter shot numerous times. That Sheriff’s Sergeant died in the hospital. God bless all of the victims and families of the victims. Thank you to Law Enforcement.”

Major news outlets such as Fox, CBS, and CNN have been extremely objective when reporting on the shooting. They have all done a superb job at reporting the facts and honoring the victims and their families.
