Dryden police are breathing a sigh of relief. They have been exonerated in the death of a man who became sick in a police jail cell. The province's Special Investigation's Unit says the man was taken into custody after being released from hospital last May for being too drunk. He became sick in jail and was taken back to the hospital, where he passed away. The S-I-U says the cause of his death isn't known, but police did nothing wrong while he was in custody.
