A 26-year-old Chicago man police say is a gang member was charged and ordered held without bond Sunday in the slaying of a 7-year-old girl who had been selling candy with her mother at the time she was fatally struck by a stray bullet.

Jerrell Dorsey, of the 1600 block of North Laramie Avenue, was charged with first-degree murder and aggravated battery with a firearm in the fatal shooting of Heaven Sutton, 7, the Chicago Tribune reports.

Dorsey, who has previously pleaded guilty to marijuana possession and other minor crimes, was ordered held without bond by Judge Adam Bourgeois Jr. in court Sunday, according to the Tribune.

Heaven was helping her mother sell candy and snow cones and playing with friends in front of her family's home around 10:30 p.m. in Chicago's North Austin neighborhood Wednesday when two men approached the home and opened fire.

Heaven, who would have been a second grader in the fall, was struck in the back before being taken to Loyola University Medical Center, where she was pronounced dead.

Police say an ongoing feud between two rival gangs was responsible for Heaven's shooting death, the Chicago Sun-Times reports. Police say Dorsey is affiliated with an area gang. A 19-year-old man whom police allege is a gang member was also wounded in the ankle during the incident.

The second offender in the shooting remains, as yet, at large, a fact frustrating to Ashake Banks, Heaven's mother.

"I still feel sick because they have someone in custody, but they don't have both of them," Banks told NBC Chicago. "I want both of them, not just one of them. So I'm still mad and I'm still upset."

Mayor Rahm Emanuel released a statement Saturday, after Dorsey was taken into police custody, thanking members of the Austin neighborhood for sharing information with police that eventually led to the man's arrest.

"No parent should have to endure this type of pain," Emanuel said in the statement, CBS Chicago reports. "Bringing Heaven’s shooter to justice will not bring her back, but I hope it will provide some level of solace to her family. We cannot lose another innocent child to violence and I will continue to fight to make sure the Chicago Police has the resources it needs to stop the violence."

Heaven's funeral will be held Friday at St. Mark International Christian Church, according to ABC Chicago.

The same weekend Dorsey was charged, at least six people were killed and 17 others -- including a 3-year-old boy -- were wounded by gun violence in Chicago, as of Sunday morning.
