The gunman who massacred 12 people at a country music bar in southern California on Wednesday night has been identified as an ex-Marine.

Ian Long, 28, opened fire on the Borderline Bar and Grill in Thousand Oaks at 11.20pm. Long had been cleared by mental health experts after an incident in his home in April, sheriffs revealed on Thursday morning.

He killed 11 people inside the bar and one of the first cops on the scene before taking his own life.

Survivors from the shooting said he looked ‘like he knew what he was doing’ as he repeatedly fired his legally purchased Glock .45 handgun.

As dozens ran for their lives, hid beneath pool tables and used bar stools to shatter the windows to escape, Long continued firing and also threw smoke grenades to confuse the crowds.

When the first police officers arrived at the scene three minutes later, Long shot one of them multiple times before shooting himself.

By the time SWAT teams arrived, he was dead. His body was found in an office inside the bar. The sheriff’s sergeant who was shot later died in hospital. He was Ron Helus, a 29-year veteran.

In total, 13 are dead; 11 people who were killed inside the bar, the sheriff’s sergeant and the gunman. Long is a former Marine who lived in nearby Newbury Park.

In April this year, deputies were called to his home amid reports of a disturbance. He was acting ‘irrationally’ and was ‘irate’ so police called in their mental health specialist. They cleared him, deciding against having him committed, and left him at the home.

It is unclear if he already owned the weapon he used to commit Wednesday’s attack or if he bought it after the April incident. Long has no criminal history except from a minor traffic infraction.

Police said on Thursday morning that the weapon had been modified by Long to hold more rounds.

‘The handgun is designed to hold 10 rounds and one in the chamber. This weapon did have an extended magazine on it.

‘We do not know at this time how many the magazine could actually hold because it’s still being processed,’ Ventura County Sheriff Geoff Dean said, adding he had ‘no idea’ what his motive for the attack was.

In addition to the 12 people he killed, ’10 to 15′ victims were injured.

According to survivors, Long was dressed in all-black, wearing a baseball cap, sunglasses and a mask covering the bottom part of his face.

He walked up to the entrance at 11.20pm and shot the bouncer before making his way into the venue.

He then shot a young female cashier before throwing smoke grenades onto the dance floor and letting off rounds into the crowd.

Survivors described how he carried the attack out with careful precision and said he had ‘perfect form’ when shooting.

The bar is popular with college kids because it allows under 21s in on Wednesday nights. Those who were not old enough to drink had black X’s stamped on their hands.

Pepperdine University confirmed on Thursday morning that some of its students were among those in the bar. It is unclear if they were among those killed.

‘The University has determined that multiple Pepperdine students were on site at Borderline Bar and Grill in Thousand Oaks. At this time, the University is working to identify and provide support to those students.

A spokesman for California Lutheran University told DailyMail.com: ‘The Cal Lutheran community is grieving over what happened last night. We know some of our students were there.

‘We are waiting for more information from law enforcement. We have canceled classes, but the campus is open and all offices will be open. Our chapel is open for anyone who wants to gather. ‘

On Thursday morning, President Trump tweeted about the mass shooting, saying: ‘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,.’

Ventura County Sheriff Geoff Dean said the scene was the worst he had seen in 41 years.

‘It’s a horrific scene in there, there is blood everywhere and the suspect is part of that, and I didn’t want to get that close and disturb the scene and possibly disturb the investigation.
