Post Mortem

The CSI team investigates the death of a retired cocktail waitress with serious cancer. Did her recovering junkie nephew or her drug dealing neighbor murder her for her pain medicine? That's the working theory until the nephew finds a miniature crime scene on his aunt's porch - an exact duplicate of the crime scene and similar to a diorama <a href='http://www.tvrage.com/CSI/episodes/419089/07x01' target='_blank'>they received earlier</a>. Elsewhere, a coroner's inquest is called to examine Greg's conduct in the events that led to <a href='http://www.tvrage.com/CSI/episodes/432680/07x04' target='_blank'>the death of Demetrius James</a> and Greg receives an unpleasant surprise at the end of the episode.
