Bensalem, Pennsylvania police arrested a 16-year-old boy on Friday after allegedly killing a girl and turning to Instagram for help with disposing of the body.

Bensalem Police said 9-1-1 operators received a call from parents of a concerned party who said their daughter received an Instagram video chat from a 16-year-old acquaintance, later identified as 16-year-old Joshua Cooper, who said he just killed someone.

In the video, Cooper flipped the video image to show the legs of a person covered in blood, before asking for help with disposing of the body.

Police said they were advised that Cooper lived in Top of the Ridge Trailer Park in Bensalem, and officers went to check the property.

As officers arrived, police said, a juvenile boy ran out from the back of the trailer.

The officers then went inside the mobile home and saw a deceased girl on the floor of the bathroom with a gunshot wound.

Police said they also noticed “substantial steps” were taken to clean up the scene.

Additional officers searched for Cooper, and a short time later he was located and taken into custody.

Cooper was charged as an adult with criminal homicide, possessing instruments of crime, and tampering with evidence.

He was arraigned in Bucks County District Court, where Justice Stacy Wertman denied bail for the suspect and sent him to Edison Juvenile Detention Center.

Police encourage anyone with information about the incident to contact Detective Ryan Kolb at 215-633-3746 or Detective Shawn Smith at 215-633-3687.
