Alexander Marley was 29 when he was found unresponsive in his vehicle in a South St. Louis County Walmart parking lot in September 2018. He had sustained a fatal gunshot wound to the head. By the next morning his family and employer had been notified; those who knew him described him as a compassionate executive chef and a Good Samaritan.

Investigators say Marley was approached at a nearby gas station by a stranger who asked for assistance. That encounter reportedly led to Marley being followed or accompanied to the Walmart lot, where he was robbed and shot. His wallet and cash were missing, and witnesses reported seeing a man jump out of the passenger side as the vehicle rolled backward.

Days after the shooting police arrested 38-year-old Jesse Michael Kelley and charged him with second-degree murder, first-degree robbery, and two counts of armed criminal action. Detectives also linked Kelley to an earlier robbery and alleged kidnapping of a teenager in the Central West End that same week. Does anyone have information about Marley’s movements that day or about the man seen leaving the car?
