On the night of May 12, 1991, 30-year-old Sedgwick County Deputy Sheriff Christopher C. Willems was killed after a traffic stop in a Wichita parking lot. Around 11:00 P.M., Willems stopped a van containing three people. He questioned the occupants, became suspicious of one man, Garland Deavers, who had an outstanding warrant and no ID, and obtained consent to search the vehicle. A small film canister with marijuana was found.

As Willems moved to arrest Garland Deavers a struggle began. During that struggle, Garland’s brother, Fred Wayne Deavers, retrieved a .357 revolver from the van, shot Willems in the upper right thigh, and then fired a second shot to the head that proved fatal. The third occupant fled and was never charged. Both Garland and Fred Deavers were arrested and later convicted; Fred Deavers was convicted of first-degree murder and received a mandatory 40-year sentence that was later overturned on a technicality, making him eligible for parole after 15 years, and he has been denied parole on multiple occasions.

If anyone knew Deputy Willems, the van’s occupants, or saw the stop that night, what information can be shared?
