This is the man accused of killing social media star Bianca Devins — fresh out of the hospital with a giant knife wound across his neck from where he attempted to take his own life.

Cops transferred Brandon Andrew Clark, 21, from St. Elizabeth Hospital in Utica to the Oneida County Jail on Thursday following a short stint there.

His booking photo, which was released by the Oneida County Sheriff’s Office, shows where he sliced his own neck after allegedly slitting Devins’ throat on Sunday. The young man is accused of killing the 17-year-old in a jealous rage after seeing her kiss another person at a concert, cops say.

Authorities told The Post on Thursday that Clark would be brought up on felony murder charges in the coming days, but wouldn’t say when his court date was “for security reasons.” He is facing up to life in prison, if convicted.

Devins will be laid to rest Friday at the Church of Our Lady of Lourdes in Utica. Her funeral is scheduled for 1 p.m.

Investigators believe Clark and the teen had been dating for several months and had met each other’s families.

“Our lives are now forever changed,” said Devins’ mother, Kimberly, in a statement released this week.

Police were still investigating the circumstances surrounding her murder on Thursday.

Clark’s father, Jason, once threatened to kill the young man’s mother in the exact same way as Devins — as well as himself. He reportedly held her hostage for 10 hours back in 2010 when Brandon was around 12 years old.

Police said Jason Clark kept authorities at bay by threatening to “cut her throat.”

Investigators, however, have no indication at the moment that Brandon was inspired by the incident.
