CHICAGO (CBS) — Chicago police have a second person in custody in the slaying of 7-year-old Heaven Sutton, who was shot and killed while selling lemonade in front of her home.

One suspect has already been charged with killing Heaven. Jerrell Dorsey, of the 1600 block of North Laramie Avenue, was charged last week with one count of first-degree murder in Sutton’s death. He was ordered held without bond. Police said Dorsey is a gangbanger and was aiming at a rival who apparently had stopped to buy lemonade.

Jerrell Dorsey, 26, was charged with one count of first-degree murder and one count of aggravated battery with a firearm.

Police said charges were pending against a second person who was in custody Thursday afternoon.

Heaven was killed on June 27 after two men approached a group of people in the 1700 block of North Luna late at night and opened fired, police said. A 19-year-old man also was shot, in the ankle.

Heaven had told her mother, Ashake Banks, 38, that she wanted to move out of North Austin – which the family had called home for six months – because of all the violence in the area.

She had just gotten her hair done for a trip to Disney World that had been planned for next month, and was outside with her mother as they sold lemonade, candy and snacks under a canopy set up in front of their home.
