The video has no sound, so it's unclear what Hill says, but it appears he threatens him to turn over his money.
Steve backs up and then throws what appears to be a wad of cash at the teen. When Hill squats down to pick up the money, Steve lunges and the two get into a scuffle.
Within seconds though, Hill starts running away and Steve doubles over, clutching a bleeding stomach wound.
The video ends with Steve walking to a van where his mother was waiting for him and falls to the ground, writhing in pain as she tries to get help.
Steve was rushed to Aventura Hospital where he died of his injuries.
Prosecutors didn't release the full surveillance video until this week, but they did circulate stills of the suspect, and received several tips saying it was Hill who carried out the armed robbery.
He was arrested two days later at a residence in Lauderhill.
Hill is in jail without bond awaiting trial for second-degree murder.
Because he was a minor at the time, he is not eligible for the death penalty, but could still spend the rest of his life in prison.
