Which actress played the Miniature Killer, Natalie Davis, on CSI?

Jessica Collins played Natalie Davis, the Miniature Killer, on CSI: Crime Scene Investigation.

Natalie Davis was the serial killer at the center of one of CSI's most elaborate long-running story arcs. She created detailed miniature replicas of crime scenes, then staged real murders to match those models. The tiny dioramas served as both clues and psychological signatures, forcing the investigators to reconstruct crimes before fully understanding who was responsible.

Collins appeared as Natalie during the 2007–08 storyline, including the episodes "Living Doll" and "Dead Doll." The character's crimes eventually led to Sara Sidle being kidnapped and left beneath a wrecked car in the desert. Natalie was captured, but the investigation continued through flashbacks and the team's effort to rescue Sara.

The actress is also credited professionally as Jessie Collins, while her birth name is Jessica Ann Collins. That naming difference can cause confusion in cast lists, but Jessica Collins is the same performer who portrayed Natalie Davis. Missi Pyle, Amy Acker, and Melinda Clarke played other television roles and were not the Miniature Killer.
