A man accused of intentionally striking a woman with his pickup truck and then transporting her dead body to a wooded area has been convicted of murder in southwestern Michigan. Authorities say Colby Martin hit 64-year-old Melody Rohrer while she was out for a walk, put the body in his vehicle and engaged in sexual acts. They didn't know each other. Martin acknowledged in a police interview that he struck Rohrer in 2021 and took the body to St. Joseph County. But he denied any sexual acts. His attorney told jurors that it was an accident. Martin faces a mandatory sentence of life in prison when he returns to court in Van Buren County.
