He had been shot three times in the head, apparently execution-style, although police are not calling it an execution.

No charges have been filed and no suspects are in custody, police said, and they were still interviewing witnesses as of Monday. The South Suburban Major Crimes Task Force and Illinois State Police are aiding in the investigation.

Jerel Bell’s older brother, Jeffrey Bell, 21, is charged in the murder of Marquetta Campbell, 26, who was shot and stabbed outside the Big Boy Submarine sandwich shop, after an argument at a bar in Matteson.
