Photo: Surveillance video captures Fred Couch's murder.
Surveillance video, obtained by the Chicago Tribune, shows 16-year-old Fred Couch being shot to death outside a convenience store on the city's South Side last Wednesday night.
Police say Couch was standing outside the store when someone came up from behind him and shot him in the back twice.

The video shows Couch falling to the ground as a man holding a gun steps into frame. The teen struggles to move, then is still.
The gunman then fled in a grey vehicle, according to police.
Couch's mother, Tojuna Smith, told CBS affiliate WBBM witnesses told her "mean mugging" - giving someone a bad look - might have had led to his murder. She said she heard the shooter accused her son of "looking at him the wrong way." Police have not confirmed that part of the story.
Police, who are examining the video, say no arrests had been made as of Friday evening.

Couch, like Albert, attended Christian Fenger Academy High School.
In September, the beating death of Derrion Albert, an honor student at Fenger, was captured by a cell phone video camera. That video attracted national attention.
Couch's father was shot to death in 1993.
