The release of a convicted killer that drew intense opposition has been delayed. Loren Herzog was due to be released Sunday. But officials with the California Department of Corrections and Rehabilitation say Herzog's release date was incorrectly calculated by the San Joaquin Superior Court. A department spokesman said Herzog, who pleaded guilty to voluntary manslaughter in the 1998 disappearance of Clements resident Cyndi Vanderheiden and was sentenced to 14 years in prison, will be held for what he termed "several weeks" more. A more definitive release date will be set after court officials recalculate Herzog's sentence. He had once been convicted of four murders and sentenced to 78 years in prison, but an appellate court threw out all but the Vanderheiden case.
