ST. LOUIS, MO – Prosecutors in St. Louis County have charged 38-year-old Michael Kelley with second degree murder, the Post-Dispatch reports. Kelley is accused of fatally shooting 29-year-old Alexander Marley in the parking lot of a south county Walmart Thursday night. Marley, who was an executive chef for Andre’s Banquets & Catering, was found shortly after 10 p.m. and taken to a hospital where he died.

Last week, police identified Kelley as a person of interest. They say he approached Marley in the parking lot of a nearby gas station before shooting him, likely in a botched robbery attempt. Kelley is also suspected of another armed robbery earlier on Thursday, in which police say he forced a 17-year-old to drive him to an ATM at gunpoint, according to the Post-Dispatch. In 2015, he served time in prison for arson.

Police are still asking anyone who may have witnessed the shooting to contact them.

Anyone with information should call St. Louis County Police at 636-529-8210 or contact St. Louis Regional Crime Stoppers toll free at 1-866-371-TIPS (8477). All callers can remain anonymous and may be eligible for a reward.
