The daughter of a psychiatric hospital nurse who was strangled has taken the first step toward suing the state over security lapses she claims led to the killing. The woman filed a claim with the California Victim Compensation and Government Claims Board. The claim filed February 2 said an alarm belt that the victim tried to activate did not work in an outdoor courtyard when a Napa State Hospital patient confronted her in October. The patient has pleaded not guilty to murder and robbery in the death. The claim alleged the 37-year-old suspect was given access to the Napa, California’s hospital grounds even though he had threatened a fellow patient. A lawsuit could be filed if the claims board does not agree to a settlement.
