A witness said Simpson and Jackson allegedly robbed three men, one of which was Jones, behind a Sunfresh, court documents say. The witness said Jones and Simpson started to fight when Simpson allegedly fired a gun.

According to court documents, surveillance video from the area showed Jackson and Simpson in the area where the shooting occurred at the time of the shooting. In the surveillance footage, both men were seen holding a Styrofoam cup, which police recovered from the scene.

DNA testing and finger prints from the cup matched to Simpson and Jackson.

Jackson County prosecutors have requested a $500,000 cash bond.
