Witnesses say that there were five people in the car, one of whom was Fluker Jr.'s father, Marlon E. Fluker Sr., who has been charged with aggravated unlawful use of a weapon and mob action in connection with the death of Marquise.
On Monday morning, the Major Case Squad, equipped with armored vehicles, joined the investigation after Griffin was found dead in a yard. They surrounded a nearby house at 7215 W. A St. in Belleville for several hours before bringing several people out for questioning.
Father and son both have previous criminal histories, having been charged with aggravated battery. Fluker Jr.'s record also included assault, home invasion, and resisting arrest. His bond has been set at $2 million, and his father's at $10,000.
