GILES COUNTY, Tenn. (WKRN) — It’s been more than 18 months since beloved businessman Jim Grimes was shot and killed on his Lynnville property. However, new advancements in technology have investigators confident the missing piece in solving the homicide is in their small Giles County community.

“Whether it’s getting rid of evidence or whether it’s assisting, we know that those people now exist, and with that information, then obviously there will be interviews forthcoming in the near future,” Lt. Shane Hunter with the Giles County Sheriff’s Department told News 2. 

What started as a homicide investigation in Giles County has become a non-stop effort with agencies across the country, including the FBI and Homeland Security. 

“I’ve been doing this for 25 years and the countless hours that people have invested is just astronomical,” said Hunter.

Investigators remain hopeful there will soon be resolution for Grimes’ loved ones with developments in fields such as genealogy and DNA analysis, as well as technological resources extending from across the world playing a vital roll.

“Such as commercial satellites that orbit,” Hunter explained. “Finding out if those satellites were actually in the vicinity during the time that this crime happened and actually obtaining imagery from those commercial satellites.”

These satellites are among the tools helping investigators nail down the events that unfolded in Lynnville on April 19, 2021.

“We’re just missing a few seconds. I’m not talking about minutes, I’m talking about seconds. That’s how tight this time frame is involved in this case,” the lieutenant emphasized.

Hunter said authorities believe those responsible for Grimes’ death have ties in the community that can help bring closure in the case, which has been detrimental for the Grimes family, as well as their neighbors.

“Obviously Lynnville is a very tightknit community, and it’s having overwhelming effects on the community knowing if there’s still a murderer amongst the community,” he said. 

The Giles County Sheriff’s Office released the following statement this week about this homicide case:
