Shortly before dawn on April 17, 2023, two men were found fatally shot inside a parked car in the 2700 block of Semple Avenue in the Wells-Goodfellow neighborhood of St. Louis. Neighbors reported hearing gunfire around 2:00 a.m., but police were not notified about suspicious occupants until roughly 5:15 a.m., when officers discovered 30-year-old Robert Cook and 43-year-old Sterling Turner Jr. Both were pronounced dead at the scene and the St. Louis Metropolitan Police Department’s homicide detectives opened an investigation.

Despite witness reports establishing a gunfire timeframe, the investigation has produced few public leads. As of late 2025, no suspects have been publicly identified, no arrests announced, and the motive remains unknown. If anyone has information about activity on Semple Avenue that night or knew Robert Cook, please share what you know with investigators.
