Melanie McGuire was released from a New Jersey jail on Saturday night. She pleaded innocent to charges of murder, desecration of a corpse, perjury and a weapons violation.
McGuire was arrested in June, 13 months after William McGuire's body washed up in three suitcases near the mouth of the Chesapeake Bay in Virginia.
The Virginia medical examiner determined that McGuire was shot at least twice, once in the head and once in the chest.
