The shooting happened on April 16, 2017, in Cleveland, Ohio. The shooter uploaded a video of the event. 
Seconds before the shooting, Stephens left his car, approached the victim and asked Godwin to say the name of Stephens's girlfriend. Stephens then said "She's the reason why this is about to happen to you", before shooting Godwin, fell to the ground and died. 
Facebook said the video was uploaded to the website after the fact, not livestreamed as it was once thought. In other Facebook posts, Stephens claimed responsibility for thirteen murders, but police said they were not true as of the moment.

This resulted in a brief pursuit by police, and a successful execution by the Pennsylvania State Police.

Why Stephens killed Godwin.
Police confirmed there was no known connection between Godwin and Stephens before the shooting and that Godwin was selected at random. Stephens's mother told police that Stephens told her by phone he was "shooting people" because he was "mad with his girlfriend" of about three years, who was confirmed to be safe and was cooperating with investigators.
