Roger Dale Crisp, 53, was found dead inside a burned minivan near Mustang Road and Southwest 44th Street in Oklahoma City on November 9, 2007. First responders determined the vehicle had been set on fire, but the medical examiner concluded the fire was not the cause of death; Crisp had been stabbed multiple times and the fire was apparently used to try to conceal the homicide.

Police say Crisp may have been in the area of Southeast 66th Street and Shields Boulevard or near Interstate 240 and Eastern Avenue on the night he was killed. Investigators have not identified a suspect or made arrests, and the motive remains unknown. His family has offered a substantial reward for information leading to an arrest.

Did anyone in Oklahoma City see Roger Crisp that night or notice suspicious activity near those intersections that could help solve this case?
