In New York, newly released video shows the final hours of the life of a diabetic prisoner at Rikers Island jail who was reportedly deprived of his insulin medication and left to slowly die. Carlos Mercado was arrested two years ago for attempting to sell a small amount of heroin to an undercover officer. He died in jail 15 hours later after guards reportedly ignored his pleas for medical help. Surveillance video released by The New York Times shows corrections officers left him on the floor for three minutes after he collapsed. He is also seen reeling and carrying around bags of his own vomit before his death.
