"This is about her. Her, her, her. It's always about her!"

Natalie Davis a.k.a. "The Miniature Killer" is a psychotic serial killer who surfaced in the seventh season of CSI: Crime Scene Investigation. She is known for being Sara Sidle's and Gil Grissom’s archenemy.

Showed up in the premiere of the seventh season, and finally being identified in the season finale. She would later reappear in season nine.


Natalie's father, Christopher Davis, was a ventriloquist who was often absent, as he was on the road.

Since his wife would stay at home to take care of Natalie and her little sister, Chloe, this wasn't a problem. When Mrs. Davis died, Mr. Davis had to stay at home more.

During this time, Natalie (who was apparently always withdrawn and quiet) became increasingly jealous of the attention Chloe got from Christopher, culminating at a block party when Natalie pushed Chloe down from a tree house in their garden, killing her.

Christopher later cleaned up Chloe's blood off the ground using bleach while Natalie was standing next to him, causing her to have psychotic (and later murderous) tendencies when she saw or smelled bleach growing up. Foul play was never suspected.

Christopher (finding himself unable to take care of Natalie alone) gave her up for adoption a short time later. She was adopted by Ernie Dell and his wife who had a sizeable number of foster children under their care.

When Mrs. Dell died, Ernie gave up care of the children, except for his only biological son, Lionel. He stayed in touch with Natalie, presumably as they shared a love of miniatures. This is why Natalie decided to make a miniature of each scene with a killed person.

In 2007, Natalie snapped completely and started killing.

Season 7[]

Built to Kill[]

Natalie began killing with her second victim Izzy Delancey. Izzy was a retired, washed-up rock-star who employed Natalie as a cleaning lady sometime before his death by her hands.

Izzy was struck on the head from behind with a marble rolling pin while he was having a meal. Having the miniature model with her, Natalie then sampled some of Izzy's blood and matched the blood pool.

As Natalie had not yet become a serial killer, it was believed to be a common murder. Suspects included his wife, ex-wife, nanny and son, but they all were exonerated.

Post Mortem[]

Natalie officially became a serial killer when she killed Penny Garden, who was a terminally cancer-ill, retired cocktail waitress. Her connection to Natalie is never revealed and it is mentioned that she had her nephew clean her house sometimes, meaning she wouldn't have to hire a professional cleaner.

Natalie poisoned her favorite liquor with liquid nicotine, intending to have her die of poisoning; however, as a result of the violent seizures that liquid nicotine causes when ingested, Penny Garden went through one of her windows and had her throat almost completely impaled by the broken glass, dying of exsanguination.

Because of this, Natalie brought the miniature back with her, altered it to match the crime scene and had Ernie Dell deliver it to the house, where Penny Garden's nephew later found it.

Loco Motives[]

Natalie struck again when she claimed the life of her third victim, Raymundo Suarez, who worked at the same Mannleigh Chicken processing plant as Ernie Dell.

By her account, Raymundo frequently flirted with Natalie whenever she came there. She killed him by knocking him unconscious, placing him in the factory stun bath and activating it, electrocuting him.

Since Ernie was a model train enthusiast and had a bunch of rather morbid miniatures in his house, he became a suspect for the Miniature killings, but was able to counter the evidence against him (he had aided Natalie in making the first two miniatures, unaware of their purpose). Ernie later confronted her about it in private.

Natalie admitted to the murders, claiming to have killed Suarez because he wouldn't leave her alone, but didn't elaborate on why she killed Delancey and Garden and promised not to kill again.

Ernie later confessed to the murders through an e-mail and webcam video to Grissom in order to protect her, killing himself to put the investigation to an end.

After this, Natalie sent a miniature of a future killing that would sit on Grissom's desk for four weeks while he was on sabbatical.

Monster in the Box[]

When Grissom returned, he found the miniature and rushed with the CSIs to find out who the house belonged to. They eventually found that it was Dr. Barbara Tallman's house who was a former psychiatrist who once did pro bono work at a psychiatric institution where Ernie Dell's biological son, Lionel, had been treated. Her link to Natalie is not specified, but it can be presumed that she also treated Natalie at some point.

As a result of Ernie's suicide, Natalie became focused on Grissom, adding a newspaper with the date of the murder onto the miniature.

It made it appear as though Tallman was to be killed by being smothered with a pillow during her afternoon nap while in actuality, Natalie had planted a time device filled with charcoal above her fireplace, releasing carbon monoxide into the air.

As the CSI team had found Tallman before the murder could be performed, they replaced her with a lookalike, Officer Kamen. During the stakeout of the apartment, Natalie's trap went off, killing Officer Kamen by carbon monoxide poisoning.

Tallman was later killed by her brother as a kind of assisted suicide, as she had grown tired of living with her Parkinson's disease, having him place the blame on the Miniature Killer. This failed, however, and he was arrested for killing his sister.

Living Doll[]

As part of a vendetta against Grissom, Natalie abducted Sara when she left the strip mall that she ate at a few times a week. She tasered her, placed her in her car and drove her out to the Nevada desert and placed her in a pit under a damaged car.

Natalie installed a small, battery-powered engine in the miniature and connected it to the Sara doll's arm, having it move as if reaching out for help. This first gave the impression that Sara was to be crushed to death.

Later, however, when Grissom saw a weather forecast predicting heavy rain, he poured some water over the miniature, disabling the engine, indicating that Natalie was going to kill Sara by having the rain drown her under the car.

Season 8[]

Dead Doll[]

Sara later made it out of the pit and was later saved in the desert. Natalie was then subsequently arrested and placed into a mental institution after having a mental breakdown.

Season 9[]

Woulda, Coulda, Shoulda[]

After her arrest, Natalie was treated for her psychosis with drugs and worked at the institution laundry room, coming into contact with bleach daily as a way to diminish its power over her. When Gil came to visit, she expressed her regret for the harm she has done to both Grissom and Sidle, but Gil appeared skeptical. Grissom later found a miniature doll carved out of a bar of soap under the floor of Natalie's cell, depicting her being hanged.

It is implied that she was planning to kill herself, but it has not yet been verified if she went ahead with it in the show.

One of the CSI novels "Shock Treatment" claims that she had indeed hung herself, but it unclear if this is considered canon in the show.

Behind the Scenes[]

Natalie's victims were killed in widely different manners, including bludgeoning, poisoning, and electrocution. She typically used their habits and routines as windows of opportunity. The majority of Natalie's victims were apparently people who employed her services as a cleaning lady (paying her in cash so that no records of her employment existed). Several of them also had some form of connection to her foster father, Ernie Dell, a model train enthusiast who helped her build her first three miniatures (not knowing what they were being used for). A possible exception is Penny Gardens, whose connection to Natalie or her foster family is never explained.

The key signature of Natalie's crimes was the incredibly accurate scale models that were built by Dell (with the exception of the miniatures of Barbara Tallman's apartment and Sara Sidle's crime scene, which she made herself after Dell's suicide) to reflect each crime scene. Each model was either left at the murder site, in the case of her male victims, or delivered to someone involved in connected to her victims or the investigation, in the case of her female victims. Every detail was thought out, and to make the models as authentic as possible, Natalie even went so far as to add the victim’s blood to the model of the victim. She also left a picture of a bloodied doll in each of the models, which were hidden among the rest of the miniatures. The doll was a representation of the doll that her father, a famous ventriloquist, made in the image of Natalie's biological sister, Chloe, whom Natalie killed when the two were children.

The miniatures of each crime scene also had an item that had something to do with bleach, ranging from barrels or vases containing bleach, to coupons for bleach. The reason behind this is Natalie's witnessing of her father cleaning Chloe's blood up with bleach after Chloe's death which gave her a psychosis that caused her to have murderous thoughts whenever she saw or smelled bleach. In her last appearance, she made a miniature of herself being hung.

If she does commit suicide this way, the methods of all her murders (except for that of her sister) spell the word BLEACH: "Bludgeon", "Liquid nicotine", "Electric", "Asphyxiation", "Car Crash", and "Hanging".
