Dayton mass shooter Connor Betts was reportedly the lead singer of a misogynistic “pornogrind” metal band called Menstrual Munchies — which released songs about rape, murder, necrophilia and other gruesome acts against women.

“I feel s–tty having let him be in the band, doing those lyrics,” said bandmate Jesse Creekbaum in an interview with VICE News. “It’s like, Jesus Christ, how much of this was like real life for him?”

Betts, 24, slaughtered nine people on Sunday — including his own sister — with an AR-style rifle before being killed by police. He also managed to wound 27.

“I know, like, whereas I saw it as a joke — like, ‘Let’s play this and we’ll shock some people,’ and then the people that we know laugh — he didn’t see it as a joke,” Creekbaum said. “He was like, ‘F–k, yeah. We’re gonna do this.’”

Pornogrind, according to Creekbaum and others in the music scene, is a subgenre of heavy metal similar to “goregrind” — but with more sexual violence.

“It’s just the music we love, you know, like, it’s fun to play. It’s energetic and there’s nothing else like it. So we play it,” said Zach Walton, member of the pornogrind band Groin Mallet. “And then we get people like this, who, you know, are f–king sick in the head, who get into our scene and ended up killing nine people and almost, you know, putting a bad name on our scene. And that’s not fair for the rest of us.”

Walton, 29, told VICE that he’s booked Menstrual Munchies, a three-man group with Betts doing vocals, at the venue he owns in Columbia, Missouri.

The band has released albums and songs with extremely violent and sexually explicit titles, such as “6 Ways of Female Butchery” and “Sexual Abuse Of A Teenage Corpse.” Creekbaum was trying his best to scrub them from the internet on Monday.

“I took it all down. I’m trying to get everyone I know to take all of it down,” he said. “I don’t want to be associated with it. I don’t want it blowing up. I don’t want him romanticized. I don’t want any of this romanticized. I want people to erase him from history.”

The band’s pages were wiped from YouTube and Facebook, though their songs and videos still remained on other websites and pages Monday. One clip, posted on the Troll Trax, showed Betts and another bandmember performing outside in ski masks and dresses.

Other members of the metal scene were denouncing Betts and distancing themselves from him on social media.

“OH TURNS OUT THE DAYTON SHOOTER WAS LITERALLY CONNOR F–KING BETTS,” wrote the band Neckbeard Deathcamp in a since-deleted tweet. “I DON’T KNOW IF I WOULD USE THE TERM LEFTIST TO DESIGNATE ONE OF THE DUDES IN MENSTRUAL MUNCHIES. ANTIFASCIST SURE. BUT NOT GREAT WITH WOMEN.”

The band added, “JUST ANOTHER DIME A DOZEN OHIO GRIND DUDE WHO CAPED PROGRESSIVE POLITICS WHILE TREATING WOMEN LIKE SHIT.”

Pornogrind rocker Ryan Ward asked the public to not look down upon the industry or its fans.

“I feel it’s our responsibility to make it a point to let people know that, no, this is not what we actually stand for,” he told VICE. “Our songs aren’t prophecies, you know, like, they’re not f–king, ominous f–king messages that are supposed to come true. They’re just songs.”

Betts was described by his bandmate as a loner who spoke about being depressed. Creekbaum confirmed reports of the alleged “hit-lists” Betts made of classmates he wanted to rape, kill and skin — saying the young man told him about them.

“I think he decided that he was going to kill himself, and he was like, ‘I don’t have the balls to do it’ and he drew a gun,” Creekbaum said.

People who went to high school with Betts said he often spoke about his violent fantasies.

“He knew it wasn’t normal,” recalled one student.
