On the afternoon of July 20, 2016, officers were called to a home in the 7300 block of Jenwood Avenue in Jennings, Missouri. Inside the residence they found two deceased adults: 40-year-old Tonya Friziellie and 46-year-old Tracy Nailor. Both victims sustained fatal gunshot wounds, and autopsies confirmed the cause of death. Detectives from the Bureau of Crimes Against Persons took over the investigation and processed the scene while canvassing the neighborhood for information.

Initial police reports said no suspects were immediately identified and there were few strong leads coming from witnesses or physical evidence. The double killing has continued to pose questions about motive and who targeted the two people in that home. If anyone has information about Tonya Friziellie, Tracy Nailor, or the events at the Jenwood Avenue residence, please share what you know with investigators.
