Gary J. Lambert, 47, was found dead outside an abandoned home on Dalton Lane in Possum Trot, Kentucky, on March 25, 2016. Investigators determined he died from a single gunshot wound to the head. A Paducah resident and firearms enthusiast, Lambert taught concealed carry at Shooters Supply and formerly owned Lambert’s Deli.

Authorities identified 38-year-old Joseph L. Cunningham of Paducah as the suspect. Cunningham and Lambert were acquainted and had arranged to meet to complete a sale of allegedly stolen firearms; the shooting occurred during that transaction. Cunningham reportedly fled in Lambert’s vehicle with his girlfriend, Kristy Keener, and the two were later stopped in Jefferson County, Illinois, driving the victim’s car. Cunningham was arrested and confessed to Illinois authorities, saying he shot Lambert in self-defense. Marshall County charged Cunningham with murder, first-degree robbery, tampering with physical evidence, and being a felon in possession of a firearm; Keener also faced charges. A trial for Cunningham was set for March 19, 2018, in Marshall County Circuit Court.

Did anyone in the area know Lambert, Cunningham, or Keener, or have information about the meeting that led to the shooting?
