Three gruesome deaths at the privately run South Florida State Hospital triggered an investigation that revealed concerns that employees were overmedicating patients and failed to call the state abuse hotline after a patient died in a scalding bathtub, according to documents obtained by The Associated Press.

State officials requested a review of the facility “in response to significant events in past several months,” including the deaths. The state also reviewed cases of individuals who had been placed into solitary confinement and restraints multiple times and other incidents at the facility, but the report offered few details of those incidents.
