The PTSD-suffering ex-Marine who slaughtered 12 people at a country music bar in California on Wednesday was updating his Instagram story throughout the massacre, it has been claimed.

Ian Long, 28, filmed himself as he opened fire on Borderline Bar and Grill in Thousand Oaks, holding his Glock .45 in one hand and his cell phone in the other, according to police sources cited by TMZ.

The footage was found on his Instagram story after he killed himself before SWAT teams entered the building and has since been wiped from the internet along with his Instagram and Facebook account.

On Facebook, he posted a chilling final message about gun control and how 'prayers and tears' were not enough to stop atrocities such as the one he committed.

His ominous social media presence has begun to emerge along with details of his life before he joined the Marines in 2008.

According to former friends and classmates, Long was bullied at Newbury Park High School for his lazy eye and could not take jokes well. One former track coach said he attacked her, groping her backside and stomach once, when she did not give him a phone he said was his.

He hoped to be a professional baseball player but was not talented enough and did not have a good rapport with other members of the varsity team.

One friend said he was 'cocky' and was 'one of those bros who drove a huge car to high school.'

Despite suffering PTSD, Long never sought help from Veterans Affairs. A VA official told DailyMail.com on Friday that he was never enrolled in any of its health programs.

'God bless all of the victims and families of the victims. Thank you to Law Enforcement,' they said.

The friend, Rebekah Homokay, told The Wall Street Journal that he set his sights on the Marines because he 'loved America and loved guns.'

His Facebook post read: 'I hope people call me insane... (laughing emojis).. wouldn't that just be a big ball of irony?

'Yeah.. I'm insane, but the only thing you people do after these shootings is 'hopes and prayers'.. or 'keep you in my thoughts'... every time... and wonder why these keep happening...'

The remarkable post, which uses language common to gun control advocates, could not be independently confirmed by DailyMail.com.

Long, a Marine combat veteran who investigators said may have had PTSD, was a regular at the bar where the shooting occurred, several of his friends said.

On Friday morning, President Trump said the shooting was 'horrible' and made him 'sick'.

'It's a disastrous problem it makes you sick to look at it. He was a war veteran, he saw some pretty bad things.

'A lot of people say he had the PTSD. That's a tough deal. It's a horrible thing. They come back, they're never the same,' he said.

He likely would have been aware that the country music bar was a regular gathering spot for survivors of the Las Vegas massacre last year, in which 58 were killed at a country music festival.

Survivors from the Thousand Oaks area regularly gathered at Borderline for mutual support, and considered the bar a 'safe haven' after the terrifying shooting in Las Vegas.

Several Las Vegas survivors were present when Long stormed the bar, and one of them, 27-year-old Telemachus Orfanos, was killed.

Many of the dead had no connection to the prior shooting, though, so it is unclear whether Long targeted the bar specifically because of its connection to the massacre in Las Vegas.

Other victims killed inside the bar included: Sean Adler, 48; Cody Coffman 22; Blake Dingman, 23; Jake Dunham, 21; Alaina Housley, 18; Justin Meek, 23; Daniel Manrique; Kristina Morisette; and Noel Sparks.

Long's page has been deleted. In a chilling final post written immediately before he launched the attack, he spoke of gun control and how 'hopes and prayers' are not enough. His page is pictured before it was taken down

Long then shot sheriff's sergeant Ron Helus, a 54-year-old, 29-year veteran who was one of the first on the scene. He died in the hospital of multiple gunshot wounds.

Between 10 and 15 people remain in hospital, some with severe injuries. The mayor has appealed for blood donations, and hundreds responded by turning out to donate.

Survivors used bar stools to smash windows to climb out of and some hid beneath pool tables. One woman ran into the kitchen and was told by staff to climb a ladder into the attic.

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

Before SWAT teams entered the building, Long took his own life in an office inside.

He used a legally purchased .45 caliber handgun to carry out the attack and had modified its magazine so it could hold more rounds.

In April, police were called to Ian Long's home in Newbury Park after neighbors heard loud crashes coming from inside the house he shared with his mother Colleen.

She lived 'in fear' of him, the neighbors said, adding that Long, who friends have described as 'cocky', was 'hell to live with.'

The neighbors already suspected that he was suffering from PTSD after returning from a tour of Afghanistan between 2010 and 2011 and say he was disrespectful and rude whenever he passed them in the street.

When police arrived at the home, they called in mental health specialists to help resolve the situation and, according to The Wall Street Journal, it took hours for them to get Long out of the house.

Inside, furniture had been tossed all over the house and there were holes in the wall including the one caused by a bullet, they said.

GUNMAN'S MARINES RECORD 2008: Long joins the Marines on August 4, 2008. He was 18 at the time.

March 3, 2013: Long leaves the Marines. The circumstances are unknown. 2013 - 2016: Long studies at the California State University Northridge and majors in athletic training Advertisement

'They couldn’t get him out for a long time, like half the day,' neighbor Richard Berge said on Thursday.

They had heard gunshots, they said, coming from inside the home and there was a bullet hole in the wall.

Despite the combination of red flags, the mental health specialists who responded decided that Long was not suitable to be involuntarily committed under Section 5150 of the California Welfare and Institutions Code.

He was never arrested and continued living in his mother's home until Wednesday night's attack.

Police are yet to reveal why he was not committed after that April incident. The law states that any qualified officer or clinician can confine a person who they suspect has a mental disorder if they are a danger to themselves, others or are 'gravely' disabled.

It is also unclear if Long bought the Glock .45 he used in Wednesday's attack before or after the April incident or if it was the same one he used to put a bullet through the wall.

The gun was legally purchased but Long, who was a machine gunner in the Marines, had modified its magazine so that it could hold 30 rounds, three times the legal limit.

He enlisted in the Marines in 2008 when he was 18 after being told that his dreams of playing professional baseball would never come to fruition.

WHY WASN'T GUNMAN COMMITTED IN APRIL AFTER 'FIRING BULLET THROUGH WALL AND HAVING STANDOFF WITH POLICE?' In April, police were called to Ian Long's home in Newbury Park after neighbors heard loud crashes coming from inside the house he shared with his mother Colleen. She lived 'in fear' of him, the neighbors said, adding that Long, who friends have described as 'cocky', was 'hell to live with.'

Meanwhile, other disturbing incidents from Long's past indicate that his mental troubles may have predated his combat service in Afghanistan.

Julie Hanson, who lives next door to Long's ranch-style home, described him as 'odd' and 'disrespectful' well before he left home a decade ago, got married and enlisted in the Marines, becoming a machine gunner.

On Long's high school yearbook page, under the section for goals after baseball, he simply responded 'death'.

'We had kids messing around, saying jokey stuff, but this definitely looks disturbing now. It's unbelievable,' Matt Goldfield, who was one of the team coaches that year, told the New York Daily News.

Goldfield and fellow coach Scott Drootin remembered Long as an 'socially awkward' kid with 'sad eyes' who quit baseball his junior year after striking the final out of a playoff game that dashed his team's hopes for a championship.

Long enlisted in the Marines at 18 and was married as a 19-year-old in Honolulu in June 2009, according to military and court records.

His military service lasted nearly five years, and he was honorably discharged with the rank of corporal in 2013, the Pentagon said. He was part of the infantry, responsible for hauling and shooting machine guns.

During his service, Long's marriage fell apart. He and his wife separated in June 2011, while he was deployed on a seven-month tour in Afghanistan.

The couple cited irreconcilable differences in divorce papers filed in May 2013, two months after Long left the Marines.

After leaving the Marines, Long returned to California. The gunman is pictured in a 2014 picture with his mother (left) and (right) while studying at California State University Northridge where he last attended classes in 2016. He dropped out of his athletic training major in 2016 after three years

Curtis Kellog, a friend who he served with, said Long had a 'great sense of humor' and was excited to return to southern California after leaving the military.

'He had a great sense of humor and like most Marines who have seen combat it could get dark at times, just like all of us.

'He was excited to get out so he could go back home, ride his motorcycle again and finish school,' he told Click 2 Houston.

Later, he enrolled at nearby California State University, Northridge, dropping out in 2016, the school said in a statement.

'I found out a little too late that just wasn't the job for me. Maybe the ego got the better of me but it took only one time for a 19 year old D-2 athlete to talk down to me and tell me how to do my job that I realized this wasn't the career I wanted to head,' he said of his departure in a March 2017 post that was uncovered by CNN on the forum Shadowspear.

Blake Winnett, who claims to have shared an apartment with Long in 2014 while he was a student at CSUN, told The New York Post that he was a 'loner' who danced alone in their garage.

'He didn't want to help anyone do anything. He was just lazy I guess,' he claimed, adding that he once responded:

'That's not my f****** job' when Winnett asked him to take out the trash.

'He wasn't violent but he was mean. He would go to the gym and then he would, I guess, try to learn dance moves or something. 'He would close the garage and be playing music and dancing in there, like sweating.

'I would open the garage and would be like, 'What are you doing?'' he said.

More recently, Long was living in his mother's home, where neighbors said they could hear frequent, aggressive shouting between the two, especially over the last year.

About 18 months ago, Don and Effie MacLeod heard 'an awful argument' and what he believes was a gunshot from the Longs' property. Don MacLeod said he did not call police but avoided speaking with Ian Long.

'I told my wife, 'Just be polite to him. If he talks, just acknowledge him, don't go into conversation with him,'' Don MacLeod said Thursday.

Sparse pictures on social media showed a happy Long family. His mother, Colleen, posted Facebook photos of her son in his military uniform in 2010 and 2011.

'My Son is home, well sort of, back in Hawaii, soon to be in Cali come January, hooray!' she wrote on Dec. 14, 2012.

Another photo from 2014 shows Ian Long with his arm draped around his mother in front of Dodger Stadium. The two were wearing Dodgers T-shirts and smiles.

But about six months ago, a next-door neighbor said he called authorities a when he heard loud banging and shouting at Long's home.

'I was concerned because I knew he had been in the military,' neighbor Tom Hanson said Thursday, as federal and local law enforcement officers searched Long's house, where an American flag flew over the garage.

Hanson described Long as an introvert and said he was 'dumbfounded' by the massacre.

Long's only other contact with authorities came after a traffic collision and after he alleged he was the victim of a violent encounter in 2015 at another bar in Thousand Oaks, the sheriff said.

Authorities haven't identified what motivated Long to open fire during college night at Borderline Bar & Grill in Thousand Oaks, around 40 miles (64 kilometers) from downtown Los Angeles. The city of about 130,000 people is consistently near the top of lists ranking the safest places in California.

The dead included 11 people inside the bar and a veteran sheriff's sergeant who was the first officer through the door.

The Marine Corps said Long earned several awards, including a Combat Action Ribbon and a Marine Corps Good Conduct Medal. He was assigned to the 2nd Battalion, 3rd Marine Regiment, Third Marine Division in Kaneohe Bay, Hawaii.

Long's mother Colleenn Long, 61, was spotted by DailyMail.com being interviewed by FBI agents on Thursday.

She emerged from her house around 1.45pm and was shepherded into another red truck resembling the one the shooter used to drive to the Borderline Bar & Grill where he carried out the massacre. She and several officers left the house in the smart suburb of Newbury Park in a convoy of three trucks.

In addition to the 11 Long killed inside the Borderline Bar and Grill on Wednesday, '10 to 15' victims were injured.

A verified GoFundMe page has been set up to help cover their medical bills. They have raised $27,000 of the $50,000 they hope to get.
