A 21-year-old New York man who allegedly killed his 17-year-old girlfriend - and then posted photos of his body on Instagram - could have done it out of jealousy after kissing another man at a concert on Saturday night. said officials.

Oneida County Attorney Scott McNamara said the prosecutor's office is likely to treat the murder of 17-year-old Bianca Devins as a case of "extreme emotional disorder" after a preliminary investigation into the events that led to her assassination , suggesting that the suspect, Brandon Clark, 21, did not plan.

He went on to say that it would probably reduce the level of crime Clark would face.

Officials said the two had attended a concert in New York City the night before the killing and are believed to have quarreled on the way home.

Bianca's body was found Sunday by police in front of a vehicle in Utica, along with Clark who was found seriously injured. He has been hospitalized and should survive.

Utica police said in a statement to Fox News: "Regarding their relationship, they learned that they had met on the Instagram social media platform about two months ago. They mainly used this means of communication and their relationship gradually evolved into an intimate relationship.

Investigators believe the man posted photos of the girl's corpse on Instagram, where at least one was widely circulated.
