Roy Scott Baker, 54, was shot and killed inside his Arnold, Missouri, home on May 14, 2016, after a domestic dispute with his live-in girlfriend. Police say the argument escalated into physical violence and that the woman pulled the trigger during the confrontation.

After the shooting she was taken into custody and the Jefferson County Prosecuting Attorney’s Office charged her with second-degree murder and armed criminal action, alleging she was responsible for Baker’s death. The case proceeded into the judicial process to establish the full circumstances and legal outcome.

If anyone knew Roy, the couple’s household, or was in that neighborhood on May 14, 2016, does any detail stand out that could shed light on what happened that evening?
