Bianca had planned to attend Mohawk Valley Community College in Utica this Autumn. She also posted an Instagram Story saying there would be a candlelit vigil held for her sister today. "Wtf is wrong with you people!??" she wrote on Monday.
According to local news reports, Clark was admitted to the hospital with lacerations after he himself called 911 following the homicide. When police arrived, Devins was already dead and Clark started to harm himself outside of an SUV, police said.
In a statement, Utica Police said the first responding officer who arrived at the home found Clark lying on the ground next to the auto, and when he spotted police, he began to stab himself.
"The male advised [the officer] that the female was beneath the tarp, and proceeded to pull out a cell phone", police said in their statement. She had extensive injuries to her neck, they said.
Police identified the victim as Devins. Clark is now being held in a correctional facility after undergoing surgery for his self-inflicted wounds, which were described as "severe" by police, though he is expected to survive.
The horrific killing of the teenager in Utica, New York, has drawn headlines, its brutality underscored by its broadcast.
On that occasion, the killer streamed live video on Facebook for 17 minutes as he fired at men, women and children at two mosques. He added that the suspect was in custody at Oneida County Jail in upstate NY.
Following the alleged murder, Clark is said to have posted photos of the vicious crime on several digital platforms. Images of the posts on that account suggested it was owned by Brandon Andrew Clark.
"I am sorry Bianca", the caption read.
A Utica police spokesman, Sgt. Michael Curley, confirmed the authenticity of the post.
During the time after her death, Clark allegedly took pictures of Devins and distributed the photos of her dead body on Discord, which is a social media platform for the 'gaming community.' Discord specializes in text, image, video and audio communication between users in a chat channel.
Clark, 21, was charged with second-degree murder.
Devins' killing highlighted long-standing questions about the ability and willingness of technology companies to regulate the content that makes their services so profitable. It's redemption, right?'. The caption accompanied an image of a vehicle driving down the road.
However, we have seen the photos (and do NOT recommend you seek them out).
Clark had a relatively small Instagram following of 3,000.
But it was on Instagram that reports of the teen's death first surfaced.
Discord expressed regrets in a statement sent by spokesman Will DeGirolamo.
Instagram confirmed with the Daily Dot that @.escty belonged to the victim and said in an email, "We disabled the @yesjuliet account for violating our policies. In the meantime, our hearts go out to Bianca's family and loved ones", a Discord spokesperson told CNN.
The police investigation revealed that Clark and Devins had met through Instagram, an image sharing platform, about two months ago and had begun a relationship. They utilised this as a means of communication primarily, and their relationship progressed into a personally intimate one.
