Chilling video diaries capture the intimate thoughts and emotions of Melanie McGuire, a woman known in her community as a caring wife, mother and nurse, as she stands trial for the gruesome murder of her husband. The videos, which McGuire recorded throughout the trial from her quiet bedroom near the New Jersey shore, provide a rare glimpse into the mind of a complex woman - a woman the prosecution believes was capable of killing her husband, dismembering his body and placing it into three suitcases before driving 300 miles and tossing his remains into the Chesapeake Bay.
