CHICAGO – Two teenagers are charged with fatally shooting a mother of three who recently moved back to Chicago.

Shari Graham was sitting in the back seat of a cab when she was shot in the back February 26th near the Wentworth Garden Homes on the South Side.

Cook County Prosecutors says Michael Whitehead, 16, and Natrell Jackson, 18, were responsible for the shooting. Whitehead and another man were reportedly seen on surveillance video from the Chicago Housing Authority firing a total of 12 gunshots toward a car that was believed to be carrying rival gang members in the 3800 block of South Princeton Avenue. The other gunman has not been charged.

At least one of those bullets entered the trunk of the cab and struck Graham. Police say Graham was in the cab, heading to get food.

Graham had moved to Texas several years ago to get away from the violence and crime, but moved back more than two months ago after the death of her infant son. She is survived by a 14-month-old son and a 3-year-old son and a 6-year-old daughter.
