On May 17, 2015, police in Normandy, Missouri, responded to a reported burglary in progress at an apartment complex on the 7700 block of Natural Bridge Road and found 68-year-old African American man Joe Davidson dead from a gunshot wound. Davidson was a retired firefighter known as Buddy to friends and family. Witnesses heard gunshots from the living room and reported encountering an armed intruder who demanded money and stole jewelry before fleeing.

The investigation quickly focused on 19-year-old Garret Watts, a Cincinnati resident who had been staying in the area. Watts was found on May 21 hiding in a closet at a home he frequented and was charged with second-degree murder, first-degree robbery, and two counts of armed criminal action. He was held on $500,000 bond awaiting trial. Prosecutors said Watts was the gunman; the defense said he was exercising at a nearby basketball court and not at the apartment when the shooting occurred. A St. Louis County jury acquitted Watts of murder and armed criminal action in March 2017.

Are there details about Davidson’s movements that day or other witnesses who haven’t come forward that could help clarify what happened?
