Despite breach of the standard of care, deceased prisoner's family cannot sue doctor for negligence

In Rouster v. County of Saginaw, the family of a County Jail prisoner brought a wrongful death claim arising out of the jail doctor's failure to provide timely and appropriate treatment.  The prisoner was being treated by the doctor for alcohol withdrawal when he suffered a perforated ulcer.  Even though the doctor's care was deemed below the standard of care, he and the County were not responsible for the resulting death because the plaintiff could not meet the requirement of showing that the government-agent actor was "deliberately indifferent" to the prisoner's suffering and medical needs.
