"The series detailed serious shortcomings in the state prison health care delivery system and described dozens of cases in which inmates died under questionable circumstances . . . Police and coroner investigations, if they existed at all, were often cursory, and record-keeping was slipshod. Only about one-third of prison officers were up-to-date in CPR . . . Almost none of the cases had been referred to the local district attorney's office for review. Few inmate families, much less the public, knew how the deaths had occurred."
