Danny Bonaduce ("The Partridge Family") Returns In A Guest-Starring Role

"Loco Motives" -- A case involving a man killed at a poultry manufacturing plant leads the CSI team closer to discovering the identity of the serial killer who leaves miniature replicas of his crime scenes, on CSI: CRIME SCENE INVESTIGATION, Thursday, Dec. 7 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Kenneth Fink directed the episode from a script by Evan Dunsky.

Danny Bonaduce ("The Partridge Family") returns in flashbacks as Izzy Delancey, an ex-rocker who was murdered and is linked to the CSI team's current case.

When the CSIs process clues at the poultry manufacturing plant, the evidence leads them to the home of a man who collects miniature trains and other miniature paraphernalia. Grissom and his team rush to link him to the other miniature killings, but a twist in the case could prevent them from gathering enough evidence to catch the killer.
