Details of Disappearance

Halford was last seen in Georgetown, Colorado on August 24, 1979, two days after her vehicle was found abandoned six and a half miles up Guanella Pass Road and tagged by the state patrol. The car's windshield was smashed on the driver's side and a skirt, bouse and underwear were inside it. Investigators believe the vehicle broke down where it was found.

Halford has never been heard from again. She is from San Jose, California and had been living in Denver, Colorado with Vincent Darrell Groves for several weeks by the time of her disappearance. A photo of him is posted with this case summary.

Groves associated with pimps and sex workers and provided them with cocaine. He was convicted of second-degree murder in the 1981 death of a 17-year-old girl and sentenced to twelve years in prison, but he was released in 1987. In 1990, he was convicted in two other women's murders and sentenced to life in prison.

He died in 1996, at the age of 42. DNA testing conducted after his death tied him to several further killings. Authorities believe he could have been responsible for as many as twenty-four murders between 1978 and 1989, most of them in the Denver area.

Halford's was the only case tied to him where the body was never found. Foul play is suspected in her disappearance due to the circumstances involved.
