Natalie Davis (a.k.a. "The Miniature Serial Killer") is a fictional character on the CBS crime drama CSI: Crime Scene Investigation, portrayed by Jessica Collins.

The Miniature Killer was introduced in the seventh season premiere as the main antagonist, and after being the main subject for the whole season, was identified in the finale. She made a one-time reappearance in season nine.

The key signature of the Miniature Killer’s crimes were meticulous scale models built to reflect each crime scene. The models were either left at the murder site or delivered to someone involved in solving the case. Every detail was accurate, and even used the victim's real blood instead of paint. Every model also contained a hidden picture of a bloodied doll and an item somehow related to bleach. Her victims were killed in widely different manners, including bludgeoning, poisoning, and electrocution. Many of her victims had employed her services as a cleaning lady (paying under the table), and several also had connections to her foster father.

The Miniature Killer's modus operandi is inspired by the Nutshell Studies of Unexplained Death, a series of intricate crime-scene dioramas that are actually used to help train the Baltimore Homicide Investigation unit. These dollhouses are explored in detail in the documentary Of Dolls and Murder.

Natalie was the elder daughter of Christopher Davis, a talented ventriloquist who billed himself as "The Great Rainone". Natalie had a younger sister named Chloe. Natalie was jealous of the attention Chloe received from their father, but the two sisters got along reasonably well until their mother died. Soon after, in 1981, Natalie's jealousy drove her over the edge, and she pushed Chloe out of a treehouse to her death. This was the first of her series of murders, and the only one that she did not recreate in miniature. When Natalie looked down from the treehouse at Chloe lying dead, the scene looked like a miniature, and Natalie became obsessed with creating miniatures of her subsequent victims and crime scenes. She later would witness her father cleaning up Chloe's blood with bleach, and bleach would become a psychotic trigger for her killings.
