MCKINNEY, Texas (AP) — A man has been sentenced to 80 years in prison for strangling a hospital co-worker to death and dumping her body beside a remote county road in 1989.

Sharon Trimble's strangulation death is the second for which Temmie Cooley has been convicted and sentenced. He already is serving a 35-year term for the 2001 strangulation death of another co-worker, Earlene Warrell.

Detectives say both had become romantically involved with Cooley when they were strangled to death and dumped partially clothed beside a country road.

Trimble's body was found beside a rural road in Collin County, north of Dallas. The Dallas Morning News reports autopsies showed that both died of ligature strangulation, which Collin County Medical Examiner William Rohr said is rare but easy to identify.
