On the afternoon of July 24, 2019, officers were called to a home in the 2600 block of Dalton Avenue in the Southwest Garden neighborhood of Saint Louis. Around 1:30 p.m., investigators found two people inside with fatal injuries. The victims were identified as 31-year-old Jill Jones, who lived on the 4100 block of Beethoven Avenue, and 56-year-old Robert Tucker, who lived at the Dalton Avenue address.

Early reports say both Jones and Tucker died of gunshot wounds. The homicide division and the medical examiner responded and opened an investigation, but police initially struggled to identify suspects. In the days and weeks after the killings there were no immediate arrests or charges, and the motive and circumstances leading to the shooting remained under investigation.

If anyone knew Jill Jones, her routines, or has information about what happened that afternoon, please come forward to investigators.
