Prosecutors declined to issue charges against Bodicky because of insufficient evidence. Police said this week that they had finished their investigation.

Several neighbors interviewed by the Post-Dispatch said that shortly after the shooting, detectives collected guns from nearby homes for ballistics testing and questioned people about Bodicky’s reported habit of shooting squirrels in his backyard.
