Pennsylvania teen murderer Maxwell Marion Morton sent a Snapchat selfie of himself with the corpse to his victim's mother. The incriminating photo showed Morton and his 16-year-old victim Ryan Mangan. The boys attended Jeannette High School in Pittsburg, Pennsylvania. Mangan was found dead by his mother after being shot in the face with a 9mm handgun, according to authorities. She also received text messages reading, "Told you I cleaned up the shells," and "Ryan was not the last one." The messages and the selfie lead police to Morton, who then found a handgun in his home. He's been charged with first-degree homicide as an adult, as well as possession of a firearm by a minor.
