19 Down…

Grissom stuns the staff when he announces he is leaving the CSI team, but a murder which appears linked to the infamous Dick and Jane Killer is what has their attention. A body is found dismembered in trash bags along the creek, which is a similar motto of the killer, but he is in jail. Grissom attends a class held by pathologist Raymond Langston, hoping it will give him insight to this case.
