DNA Leads To Arrest In '05 Slaying Of Woman

(AP) WASCO, Calif. Authorities say DNA evidence has helped them make an arrest in the 2005 murder of an elderly Kern County women.

Joseph Rene Castillo, 20, who was serving time in Wasco State Prison for violating parole on a drug conviction, was arrested at the prison last week on suspicion of murder, robbery and burglary.

Castillo was arrested after authorities say he was linked to the murder of Elizabeth Gayle Cook, 74, who was stabbed to death in her Wasco home in July of 2005.

Authorities say DNA found at the crime scene matched Castillo's DNA in a database with the California Department of Justice.
