The upstate man accused of killing teenage social media star Bianca Devins and then posting grisly photos of her lifeless body on Instagram pleaded not guilty on Monday.
Police say 21-year-old Clark met Devins on Instagram about two months ago. Authorities say they attended a concert in New York City on July 13 where they got into an argument.
Brandon Clark, 21, had been charged with second-degree murder for allegedly slitting his 17-year-old girlfriend’s throat earlier this month. Prosecutors say Clark used a large knife to kill Devins in Utica early the next morning, then stabbed himself in the neck and took selfies on a tarp covering her body.
