A Pennsylvania teenager was arrested after authorities accused him of showing the body of a person who had been fatally shot during an Instagram video chat with an acquaintance.

The 16-year-old suspect, who was taken into custody Friday in Bensalem, northeast of Philadelphia, is alleged to have asked for help disposing of the body during the call, the city’s police department said in a news release. …

Authorities were alerted to the apparent killing at 4:11 p.m., when a woman called 911 and said an acquaintance of her daughter’s had called her on Instagram, the police department said.

Police alleged that the teen confessed to the killing and flipped the video, showing the legs and feet of a person covered in blood.

“He then asked for assistance with disposal of the body,” they said.
