CHICAGO (STMW) — A man is charged with murder for fatally shooting a 16-year-old Tuesday in the South Shore neighborhood.

Robert Smith, 21, of the 7600 block of South Coles Avenue, is charged with first-degree murder in the Sept. 30 shooting death of 16-year-old Camerion Blair, authorities said.

Blair was in the 2600 block of East 73rd Street about 6:10 p.m. when he was shot in the back and buttocks, according to police and the Cook County medical examiner’s office.

Prosecutors said the two are members of opposing gang factions, and that surveillance video captured Smith and another suspect both approaching and fleeing from the scene of the shooting.

Blair, who lived in the 7300 block of South Shore Drive, was pronounced dead at the scene at 6:25 p.m., according to the medical examiner’s office.

Smith was arrested after a search of his home, prosecutors said. He was positively identified in a photo lineup and allegedly admitted to the shooting.

He was ordered held without bond at a hearing Saturday and will next appear in court Oct. 6.
