Ryan Aldridge, 28, was found dead of gunshot wounds on the afternoon of Sunday, December 9, 2018, outside the Oak Park Apartments in the 11100 block of Riaza Square in the Spanish Lake neighborhood of St. Louis County. The St. Louis County Police Department’s Crimes Against Persons Bureau opened an investigation.

Days after the shooting, 25-year-old Michael Clark was arrested and later charged with first-degree murder, first-degree robbery and two counts of armed criminal action. Investigators say security camera footage from the parking lot captured an altercation: Aldridge exited his vehicle, a confrontation followed, the footage reportedly shows Aldridge running off-camera with Clark pursuing him while armed, and shell casings at the scene were linked to a gun belonging to Clark. Prosecutors also allege Clark tried to start Aldridge’s car after the shooting; bond was set at $500,000.

Does anyone have information about Ryan’s movements that afternoon or additional footage from the Oak Park Apartments parking area?
