Calvin Hayes, 44, was found dead inside a vacant structure in St. Louis, Missouri, on July 10, 2019. Officers who responded to the scene determined he had suffered fatal injuries consistent with a shooting. The building was unoccupied at the time and became the focus of a homicide investigation.

Detectives from the St. Louis Metropolitan Police Department processed the scene for evidence and sought leads from the community, but the circumstances that led Hayes to be in the vacant property and who he might have met there were not clear. The investigation has struggled to produce significant breakthroughs; no suspects have been arrested in connection with the killing. The case remains an unsolved homicide, and Hayes family and the community continue to await answers.

If anyone has information about Hayes, his movements on July 10, 2019, or the vacant building where he was found, please share what is known.
