A high school football player allegedly shot classmate Ryan Mangan in the face and posted a photo of himself with his victim’s dead body, on Snapchat. He then text messaged the murdered teen’s girlfriend. Brianna Kelly, Mangan’s girlfriend, told WTAE, Pittsburg, she didn’t see the message until the day after her boyfriend’s death.

"The night it happened, he messaged me and was just like, 'Yo.' The next day, I didn't read it until Thursday, and I was like, 'What's up?' He was like, 'Ryan got shot in the head. I'm sorry,'" Kelly told WTAE

Maxwell Marion Morton 16, has been charged as an adult with first-degree murder, and allegedly confessed to police in the killing of 16-year-old Ryan Mangan in a suburb of Pittsburg, Pennsylvania.

Mangan's mother came home to her son’s corpse on Wednesday afternoon.

According to an affidavit, police arrested Morton on Friday after someone sent them a photo showing Morton with Mangan's body sitting in a chair, according to an affidavit.

Apparently another student had received the terrifying picture via snapchat, and saved it before it disappeared, according to the Pittsburgh Post-Gazette. The boy's mother contacted police after discovering her son had a photo of the murder scene.

There was also a text message from Morton to the boy saying, "Ryan was not the last one," CBS Pittsburgh reports.

Morton and Mangan had been life long friends and the accused killer is mourning the teen’s death. "'It's going to be rough. He was my A1. It's not going to be the same without him,'" Brianna Kelly said Morton told her, according to WTAE.

A 9-mm handgun was found by police in Morton's basement as well as a spent casing from a 9-mm handgun, according to reports.

Morton has also been charged with criminal homicide and possession of a firearm.

Various Instagram photos of the victim show Mangan holding guns on social media. “9 On Me #WhoSaidIAintOnS---,” Mangan captioned one photo. “Let a n---- try me #Gang,” another said.

Morton is trying to claim the shooting was an accident, but his friends don’t buy his story. He smiled in a photo with Mangan’s body in the background and then sent it to a friend.

“[Police] received a copy of the photo, which depicted the victim sitting in the chair with a gunshot wound to the face,” according to a police affidavit obtained by Pittsburg Tribune-Review. “It also depicts a black male taking the ‘selfie,’ with his face facing the camera and the victim behind him. The photo had the name ‘Maxwell’ across the top.”

Friends are haunted by one word: Why? "I want to know why they did it to him. Why they would leave his body for his mother to clean up. And then stand here, blatantly smile at a phone while somebody is in the background with a gunshot to their face?" friend Joscelyn Elias told WTAE. "How do you accidentally take a picture? How do you accidentally take a selfie? You don't do that. You don't," Kelly said.

Mangan's friends set up a GoFundMe account set up to help offset funeral expenses.

"You think you're cool and you're going to be famous because you killed someone. No, you're not the famous one. Ryan is the famous one," friend Haley Farro said.
