SUTTER COUNTY, Calif. - The California man once known as the nation's most prolific serial killer died at 85 on Monday.
The State Department of Corrections and Rehabilitation said Juan Corona died Monday of natural causes.
Corona was convicted in 1971 of killing 25 farm laborers and burying their bodies in shallow graves along the Feather River in Sutter County.
Prosecutors say he met his victims through his farm-labor contracting business.
Corona was serving 25 consecutive life sentences and had been denied parole eight times.
