JUNE 23--After allegedly killing a man in the parking lot of a Tennessee IHOP, a Memphis teenager sent friends a Snapchat photo of the victim along with the message “I just killed a motherfucker 10 minutes ago."

Sebastian Vaughn, 16, was arrested yesterday and charged in the shooting death of Marlo Williams, 35, who was found dead Monday inside a vehicle outside the restaurant.

Charged with second-degree murder, Vaughn is being held in the county’s juvenile detention facility. In an e-mail, a Memphis Police Department spokesperson said that since Vaughn is a minor “we do not have a booking photo for release,” nor will cops “release any personal information regarding victims or suspects.”

Detectives, who seized Vaughn’s cell phone, suspect that family members may have aided the teen suspect.

The Snapchat image of Williams (seen above, blurred) shows him slumped at the wheel of a Lexus and bleeding from a gunshot wound to the chest.

Responding to a man down call, police discovered Williams in the car around 4:40 PM. Soon after, he was pronounced dead at the scene.

At least one recipient of Vaughn’s Snapchat message contacted cops and provided homicide investigators with the grisly image. Williams is pictured below in a photo from his Facebook page.
