Authorities said the death of a 72-year-old woman in Munford in February has been ruled a homicide.
The Tennessee Bureau of Investigation said Thursday authorities have been looking for a red Chevy Colorado mid-sized truck with unique rims and possible bumper damage in the probe into the death of Anita Rieben.
Authorities said the truck was seen at or near the home where Rieben was found dead on February 17.
Police found her body after performing a welfare check after Rieben missed an appointment on that day.
Anyone who saw the Chevy Colorado on Reeder Street around the time of Rieben's death has been asked to call 1-800-TBI-FIND (1-800-824-3463).
