In the spring of 2005, a sense of unease settled over a Knoxville neighborhood when Gilbert Marc Grimm, 38, was found dead at his home on Upchurch Road. On May 2, 2005, Grimm was discovered to have been fatally shot, and the Knoxville Police Department opened a homicide investigation into his death.

Investigators worked in the days and weeks after the shooting but publicly identified no suspects and made no arrests. The case remains unsolved and open, with investigators revisiting the evidence periodically in hopes that new leads or technology might produce answers. Very little else has been reported about the circumstances inside the house on Upchurch Road.

If anyone knew Gilbert, lived in that neighborhood in 2005, or has information about the shooting, please share what you know with the Knoxville Police Department.
