On Sunday, at around 9 p.m., Kimberly Touchton, 22,left her mobile homewith her dog,The Macon Telegraphreported.

The walk was nothing out of the ordinary for Touchton, who was usually gone for about 10 to 15 minutes each time, so when she didn’t return home her fiancé began to worry, according to the outlet. After about 45 minutes, Touchton’s fiancé discovered her dog had returned without her, prompting him to search the area.

Minutes into the search, Touchton was found unresponsive, lying face-down about 10 to 15 feet off the road near Georgia State Route 49 and Highway 11, Houston County Sheriff’s Lt. Kent Bankston toldThe Macon Telegraph.

After making the harrowing discovery, Touchton’s fiancé immediately dialed for help. Touchton was rushed to the Houston Medical Center, where she was pronounced dead.

“It snapped her neck,” Bankston, who alsospoke toThe Atlanta Journal Constitution, said of the tire. “She probably didn’t even know what hit her, I think.”

“It came off right there and traveled probably 300 yards or more before it actually struck her,” Bankston toldAJC. “The crime scene is easily 400 to 450 yards long.”

“While [deputies] were out there, they ran across this vehicle that was probably a quarter of a mile down the road near the Bibb-Houston county line,” Bankston toldAJC. “It was missing the whole wheel assembly and tire. It was gone. That alerted our suspicion.”
