N.Y. teen may have been killed in jealous rage after she kissed someone at concert

NEW YORK — The upstate New York teen who was murdered over the weekend may have been killed in a jealous rage by her boyfriend after she kissed someone else at a concert in Queens, according to authorities.

Bianca Devins, 17, had attended the Nicole Dollanganger performance in New York City on Saturday night with beau Brandon Clark, according to authorities. She was found dead early the following morning in Utica and Clark, 21, was charged with second-degree murder.

Investigators say the couple began to argue at the venue, and the dispute intensified when they returned to Utica. Authorities say Clark used a knife to kill Devins and also to harm himself.

“The belief is that she kissed somebody at the concert and that’s what upset him,” Oneida County District Attorney Scott McNamara told Utica TV station WKTV on Tuesday. “I have a very hard time understanding how anybody can justify taking another young person’s life because they kissed somebody else.”

Cops say Clark posted graphic photos of Devins’ dead body online following the slaying. The pictures were widely shared on such outlets as Instagram, 4chan and Discord, and some struggled to quickly remove the content. Images continued to appear on Instagram as recently as Tuesday, according to Fast Company.

“Our thoughts go out to those affected by this tragic event,” a spokesperson for Facebook, which owns Instagram, told Fast Company. “We are taking every measure to remove this content from our platforms.”

Dollanganger, whose concert Devins attended, urged people to stop sharing the “horrific” content earlier this week.

“What happened to this beautiful angel was evil, cruel and senseless,” she wrote. “I am so heartbroken for her and all her loved ones.”

Clark, who lives in Bridgewater, which is near Utica, met the teen two months ago on Instagram, and their relationship progressed into a “personally intimate one,” according to the Utica Police Department.

“The headline is out there, ‘boyfriend kills girlfriend and posts photograph on social media’ and most people think the investigation is complete and it’s done and over with,” McNamara told WKTV.

Authorities are trying to determine whether the slaying was “preplanned.”

“Under the law, there’s something called extreme emotional disturbance,” McNamara told the station. “It doesn’t negate the crime, but it mitigates it. What I mean by that is it doesn’t make it so you’re not guilty, it just reduces the level of crime, so it would knock it from a murder second to manslaughter in the first degree.”

Nine years ago, Brandon Clark's father, Jason, held Brandon's mother hostage in a stand-off with Fulton police and an Oswego County SWAT team in Fulton.
