In which season did the 'Miniature Killer' storyline air?

The “Miniature Killer” storyline aired in Season 7 of CSI: Crime Scene Investigation. The mystery centers on carefully constructed dollhouse crime scenes that reproduce real murders, challenging the Las Vegas team to identify both the victims and the person creating the miniatures.

The storyline’s main antagonist is Natalie Davis, a troubled woman who works as a lab technician and secretly builds the miniature scenes. Her identity is gradually uncovered through recurring evidence rather than revealed in a single standalone case. The miniatures are disturbing because they function as both crime scenes and psychological messages, forcing investigators to reconstruct events at an unusual scale.

Season 7 originally aired during the 2006–07 television season. The arc is associated particularly with the episodes “Built to Kill,” “The Good, the Bad and the Dominatrix,” “Living Legend,” “Monster in the Box” and “The Case of the Cross-Dressing Carp.” Viewers sometimes place the storyline in Season 6 or Season 8 because its investigation continues across several episodes, but its central arc belongs to Season 7.
