A Cicero man is a “person of interest" in the grisly killing of a teen-age girl who was discovered dead outside her car in Utica, police said today.

Brandon Andrew Clark, 21, of Cicero is accused of slitting the 17-year-old’s throat, according to Utica police. She has been identified as Bianca Devins of the Utica area, police said.

Clark then slit his own throat, police said. He is currently hospitalized with severe self-inflicted injuries, police said.

Clark shared photos of the dead woman on social media, police said. Utica police said these have been authenticated. A video circulating has not been authenticated, police said.

The photos of her body are being posted on various social media sites. Some sites have removed the photos.

Police said Monday that they responded to a number of calls “regarding an attempt to locate” two people. They then found a woman dead and a critically injured man on Poe Street.

The investigation of the death delayed part of the nearby Boilermaker race on Sunday.
