Robert Lovings Polk was 22 and an Army veteran when he disappeared after leaving his mother’s home in St. Louis to look at a used car he had found on Craigslist. He had recently returned from Kentucky and was reportedly making plans for his future. Polk set out on October 3, 2015 for that appointment and failed to return, prompting a search.

His body was found in an alley on a Thursday in October 2015. An autopsy determined he died from a gunshot wound, and the death was classified as a homicide — the city recorded it as its 159th homicide that year. Investigative records list the case as an open homicide, and there have been no reports of arrests or suspects being charged.

If anyone knew Robert, saw him on or after October 3, 2015, or has information about the Craigslist meeting, please come forward with what was seen or known.
