However, in 2014, detectives located Bell in Tennessee and obtained a DNA sample along with his admission of being with Horner in the vehicle.

Deputy District Attorney Denise Yoakum, who is assigned to the Cold Case Unit, explained a cigarette butt in the vehicle was found years later, during a fresh look into the case.

“Thanks to advances in DNA technology, and the work of the Sheriff’s Department, we were able to match Mr. Bell’s DNA to the cigarette butt as well as his fingerprints,” Yoakum said.

Jurors subsequently found Bell guilty of murder in March.
