Authorities say a western Pennsylvania teenager charged in the shooting death of another teen took a selfie with the body and sent it to a friend on social media.

The 16-year-old boy is charged with homicide and a firearms count in the death of 16-year-old Ryan Mangan, who was found Wednesday evening in his Jeannette home.

Police were contacted by the mother of another boy who said he'd received a photo showing the suspect with the victim after he'd been shot, and also received text messages from the suspect saying "Told you I cleaned up the shells" and "Ryan was not the last one."

Westmoreland County District Attorney John Peck tells the Pittsburgh Tribune Review that the photo "was a key piece of evidence that led investigators to the defendant."
