Officer Joann Virginia Liscombe, 38, was shot during a January 1991 patrol in St. Louis County. A sixteen-year department veteran with several commendations, she radioed a pedestrian check at about 1:13 a.m. on January 11 near Patricia Ridge Drive and Old Halls Ferry Road. When she failed to respond to further radio calls, a backup officer went to the area and found her lying face down in the snow, having been shot multiple times. She was taken to a hospital and died on January 14, 1991.

Investigators tracked the stop to a nearby 7-Eleven where a customer had reported a man behaving strangely. Evidence indicated a struggle and that Liscombe was shot with her own service revolver; her patrol car was found abandoned less than a mile away. Dennis Blackman was arrested and later charged in connection with her killing; the case proceeded to trial and produced a conviction for second-degree murder and armed criminal action.

Did anyone in the area at the time see Officer Liscombe’s patrol car or the man near the 7-Eleven that night?
