PICTURED: Columbine-obsessed Wisconsin school ‘shooter’, 14, who was shot dead by police after pointing pellet gun at them

The gunman killed by police at a Wisconsin high school was a 14-year-old student obsessed with the Columbine school massacre and who wanted his classmates to experience “real fear.”

Damian Haglund died in a flurry of gunfire at Mount Horeb Middle School on Wednesday morning, leaving behind a chilling manifesto naming some of the schoolchildren he wanted dead.

Haglund operated a series of anonymized social media accounts and ominously posted “My last morning” in his final tweet just two hours before his attack.

Weeks earlier he revealed how his obsession with school massacres had ‘ruined’ his life.

“Not just Columbine, Sandy Hook, Ecole Polytech, Kerch, all the school movies. No one understands ‘Columbiners’, few even know what it is.

“There are helplines for porn addiction, there are helplines for suicidal people, drunks, pedos, rapists, BUT NO ONE ON EARTH CAN HELP ME.”

Witnesses reported seeing him shoot in a cafeteria after trying to break a window with the butt of a “long gun” during eighth-grade lunch around 11:15 a.m. before being tackled by a school police officer from Mount Horeb.

“People my age are actually the real enemy,” he wrote. ‘They bring me the most hatred. If you don’t play the game, if you don’t feed the machine, you’re a pariah.’

The entire school district was placed on hard lockdown, with some students only released to parents in the early evening as police tried to determine if the shooter was acting alone.

Jeanne Keller heard about five gunshots ringing from her shop, The Quilting Jeanne, several feet away on the same block.

“It might have looked like pow-pow-pow-pow. I thought it was fireworks. I went outside and saw all the kids running, I probably saw 200 kids.”

Max Kelly, 12, was among a class of students practicing in-line skating in the school gym when the gunfire rang out.

He said their teacher told them to run and they, still on skates, ran into the street.

Photos showed a ditch full of skates that were hastily thrown away by the students before they ran to nearby convenience stores and a gas station where they hid in bathrooms.

The class was still shoeless when they were reunited with their terrified parents outside the school.

“I don’t think anywhere is safe anymore,” said Max’s mother, Alison Kelly, 32.

In his blog, Haglund singled out a classmate he hated and fantasized about seeing her hit by a truck.

“Like how her skull popped from the pressure when the wheels crushed the skull, the scream.

“And some kids are just so stupid, I hope they experience real fear in their lives somehow.”

He listed ‘Diversity and Feminists’ among his ‘hates’, and wrote about how he feared women.

“I don’t mean to be completely wolfish, but I have a very different side to what people at school see me as,” he added.

He recounted a visit to Weston High School in Cazenovia, north of Madison, where Principal John Klang was fatally shot during a school shooting in 2006.

“When I went there, the energy was powerful,” he claimed.

“I went outside and touched the walls of the school, but I didn’t want to get arrested or anything.”

He wrote, “Ever since I was a kid, I wanted to be famous,” and photos on his family’s Facebook pages show a smiling Haglund apparently enjoying family trips to Canada and seeing last month’s solar eclipse.

But his messages also spoke of his own suicidal thoughts.

‘You have to understand the huge wall I’m up against. Which therapist can help me? I face worse criminal penalties than those for suicidal tendencies,” he wrote.

‘I hate my existence because I’m afraid of everything, I’m tired of this.

“My family thinks I actually have a plan after high school, no, I don’t, and if my parents ever look back, they might see that they knew NOTHING about me, and I don’t blame them. ‘

Days before his death, he updated his blog and warned, “It seems like time is running out for me and there’s no turning back for whatever I do.

“I’m sure my town, ‘Mt Horeb’, will provide many interesting connections.”

In a tweet the night before his death, he wrote: “I want to continue indulging in media, late-night core, video games, but as you continue to live, these simple things become so mundane. I’m going to miss you.’

The investigation is being led by the Wisconsin Department of Justice, and on Wednesday evening Attorney General Josh Kaul said at a news conference that he did not believe there was an ongoing threat.

In a statement on Sunday, his office revealed that the “long gun” Haglund was carrying was a Ruger .1777 caliber pellet rifle.

“Officers ordered the subject to drop the weapon, but the subject did not comply,” he added.

“The subject pointed the weapon at the officers, at which point the police fired their firearms, striking the subject. Life-saving measures were taken, but the victim died at the scene.”

“No law enforcement officers or witnesses were injured during the incident.”

He confirmed Thursday that more than one officer had fired at Haglund, amid reports that as many as 12 shots had been fired.

Mount Horeb Police Chief Doug Vierck called on the public not to spread “rumors” about the case, stressing that authorities are “working as quickly as possible to move forward so we can achieve closure.”

“Before you share information, ask yourself, ‘Is it true?’ “Can I absolutely know it’s true?” he demanded.

“If either answer is no, then don’t share the information. In the interest of everyone involved, please do not spread rumors.”

“The outpouring of support from businesses, other agencies and the community as a whole is extremely humbling.”

But his department referred calls for information to the DoJ, which did not respond to questions Thursday.
