Thousand Oaks Bar Shooting Suspect Posted on Instagram During Massacre Possible Revenge Motive 
 
 Thousand Oaks Bar Shooter Ian Long Posted on Instagram During Killings 
 
 EXCLUSIVE 
 
 12:15 PM PT -- Our sources say Long posted the same message on his Instagram and Facebook, "I hope people call me insane .. 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 shooter who terrorized college students at Borderline Bar & Grill was shockingly on social media as he shot a dozen people dead, and, based on what we now know, it sounds like they were revenge killings. 
 
 Law enforcement sources tell us Ian Long held a gun in one hand and his phone in the other, posting messages on his Instagram during Wednesday night's massacre. 
 
 Our sources say investigators discovered the messages on Long's page several hours after the shooting and contacted Instagram to delete his page. We don't know precisely what he was saying, but it appears he had a grudge he was carrying out. 
 
 A former classmate of Long's tells TMZ, Long was bullied in high school. She says his fellow students made fun of him because he had a lazy eye, and it affected him deeply. The classmate says a lot of those students go to that bar on Wednesday nights. She says he knew some of the people who teased him would be there. 
 
 We're told he was a regular at the bar, usually keeping to himself ... grabbing a beer and sitting at the bar. 
 
 As we reported, Long served in Afghanistan from 2010 to 2011 as a decorated member of the Marines. His classmate says Long suffered serious PTSD after his tour and tried to get help from therapists and doctors. We're told he also reached out to the military for help, but his mental health was in bad shape. ||||| Breaking News Emails Get breaking news alerts and special reports.

 The former Marine who fatally shot 12 people inside a California bar posted a message on social media during the attack saying he was bored but sane, law enforcement officials told NBC News. 
 
 Ian David Long, 28, also wrote that he knew his mental state would be debated for years, law enforcement officials said. 
 
 Long made two separate posts amid his shooting rampage at the Borderline Bar and Grill in Thousand Oaks Wednesday night, the officials said. 
 
 The law enforcement sources did not specify which social media platforms he used. 
 
 A spokesperson for Facebook, which owns Instagram, declined to comment on whether anything had been posted to Facebook or Instagram. Facebook also said no story was posted on Instagram but wouldn't elaborate further, deferring to law enforcement. 
 
 Twitter did not return a request for comment. 
 
 On Thursday, Facebook spokeswoman Sarah Pollack said: "Our hearts are with the victims and families affected by this horrendous act. We've removed the shooter's accounts from Facebook and Instagram and will remove any praise or support for the crime or the shooter as soon as we're aware." 
 
 Long’s use of social media was first reported by TMZ. 
 
 Investigators are still piecing together a precise timeline on the shooting that killed 12 bar employees and patrons. But it's believed that Long, who was dressed in black and armed with a high-powered Glock handgun with an extended magazine, entered the Borderline Bar & Grill about 11:15 p.m. 
 
 It's not exactly clear when he posted the social media messages, but law enforcement officials said that he walked to the back of the bar after hearing the sounds of police sirens and began indiscriminately firing on patrons. 
 
 The officials said he took a position of cover before fatally shooting Sgt. Ron Helus of the Ventura County Sheriff's Office. 
 
 Investigators believe Long then shot additional victims inside the bathroom stalls, as well as at least one person who was trying to escape through the bathroom window, the law enforcement officials said.

 A short time later, Long was found dead of a suspected self-inflicted gunshot wound. 
 
 Authorities said Long, a former Marine gunner who served one tour in Afghanistan, had been experiencing emotional issues. 
 
 Investigators are still trying to figure out the motive for the attack. 
 
 When authorities entered his home in nearby Newbury Park, they found evidence that he punched multiple holes in the walls, law enforcement officials said. 
 
 Local cops were called to his home for a domestic disturbance earlier this year, authorities said. Long was found to be "somewhat irate" and "acting a little irrationally" but he wasn't taken into custody. ||||| Standing at the microphones, from left to right, Paul Delacourt, assistant director for the FBI Los Angeles, and U.S. Rep.

 President Donald Trump is blaming mental illness for the California bar shooting that left 13 people dead, including the shooter. 
 
 Trump, speaking to reporters at the White House on Friday, described gunman Ian David Long as "a very sick puppy" who had "a lot of problems." 
 
 Long, who opened fire at the country music bar in Thousand Oaks on Wednesday, was seen by a mental health specialist in April who worried the 28-year-old Marine veteran might have post-traumatic stress disorder. Investigators have not commented on a motive for the shooting, or whether mental illness played a role. 
 
 Trump touted his efforts to fund PTSD among veterans. But he declined to engage on questions on whether the nation needed stricter gun control laws. 
 
 Trump has closely aligned himself with the powerful gun lobbying group, the National Rifle Association, and has resisted calls for tougher firearms measures.
– The man who authorities say shot to death 12 people at a California bar on Wednesday was posting to social media during the attack, according to NBC. TMZ reports that sources say that Ian Long, a 28-year-old former Marine who also died in the attack, had a gun in one hand and his phone in the other during his rampage at the Borderline Bar and Grill in Thousand Oaks and posted a message to Instagram and Facebook, writing in part: “I hope people call me insane .. wouldn’t that just be a big ball of irony.” Facebook, which owns Instagram, declined NBC’s request for a comment, but did say that it had taken down Long’s accounts “and will remove any praise or support for the crime or the shooter as soon as we’re aware.” A law enforcement official tells the AP that investigators still haven’t determined a motive for the attack, adding that they are looking onto whether Long, who they believe killed himself, thought his ex-girlfriend would be at the bar. TMZ sources say that the attack was motivated by revenge, with one saying that Long had been bullied in high school and many of those former classmates often spent Wednesdays at the bar, where Long was reportedly a regular.
