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 335-bed facility, located in Broward County, is operated by The GEO Group Inc., a Boca Raton-based firm that is one of the world's largest private operators of prisons and detention centers. Many of the patients are mentally ill and admitted against their will because they are considered a threat to themselves or others.
