Yet none of the reports noted that the remaining patients were being cared for by the untrained staff members. State law requires caregivers to have 10 hours of training before tending to residents in assisted-care facilities.
No action was taken until the staffers called 911 and an Alameda County fire captain had the remaining residents evacuated to hospitals.
California Gov. Jerry Brown said he is following developments in the Valley Springs case and would "take the appropriate action."
The newspaper also found that the home's owner, Herminigilda Manuel, received California Department of Social Services approval to run the facility despite her history of putting patients in "imminent jeopardy" at nursing homes she had owned previously.
Manuel had owned two nursing homes, which, unlike assisted-care homes, can provide medical care.
