CSI: Crime Scene Investigation

A young woman, Wendy Garner, is speeding when she's pulled over by a police officer. She explains to the officer that she's being pursued, and offers to show him a videotape she has. The officer turns her down. The scene shifts--Wendy lies dead in her car, Grissom examining the deep neck wound that killed her. Catherine finds Wendy's camcorder, but there's no tape inside. Grissom indicates that Wendy was cut below the throat as well, indicating her genital region.

David Phillips autopsies Wendy while Catherine looks on. He notes her large engagement ring, as well as the cosmetic surgery she's had, including breast implants and collagen in her lips. Meanwhile, Warrick and Sara go over Wendy's car. Sara is puzzled to discover two IDs in the car: Wendy's, which identifies her as a dancer at the Tangiers, and the driver's license and car registration of one Walter Clancy, a young, dark-haired man.

Dr. Robbins clears the mystery up: Wendy had gender reassignment surgery. Grissom posits that perhaps this is why her throat (where her Adam's Apple would have been) and genitals were cut. Catherine notes that it looks like a sexual assault turned into a hate crime.

Brass questions Officer Mann, the cop who pulled Wendy over. He claims he never looked at Wendy's videos, and that he let her go with a warning. Brass is suspicious of Mann's motivations, and suggests that perhaps Mann wanted sexual favors from Wendy and things went sour when he discovered Wendy had once been a man. Even when Brass brings up Mann's history of sexual harassment, Mann sticks to his story.

Catherine finds two matches to Wendy's prints: Wendy and Walter Clancy. Using a computer program, Archie adjusts Wendy's picture and transforms her back into Archie. Mia finds a seminal trace in Wendy's mouth, while Sara uses the serial number on Wendy's ring to trace it to her fiancé, Aaron Laner.

When Brass and Grissom visit Laner, it becomes clear that he had no idea that Wendy had once been Warren. The two met in a grief group--Aaron was mourning his wife, while Wendy was grieving for her ^twin brother,^ Warren. Aaron and Wendy lived together, but were waiting until after their wedding to have sex. Upstairs, Sara discovers a bloody pad in the trash, as well as many bottles of pills and two post-it notes: one with instructions on taking the pills, and the other with several numbers on it.

Grissom and Catherine go to the Tangiers, where they question Wendy's fellow dancers. Several of them have had gender reassignment surgery like Wendy had, and they suggest she may have gone to a Dr. Mercer, known as being the best in his field. Mercer tells the CSIs that Wendy wanted to rush the gender reassignment surgery and was turned down by his clinic. He's shocked and sorry to hear about her death.

Mia examines the bloodied pad and identifies the blood as not being menstrual, but belonging to Wendy. Wendy was draining blood from elsewhere and putting it on pads to fake having a period. Mia thinks she must have had help. Greg tells Grissom that the drugs Wendy was taking were a post surgical cocktail of mostly illegal drugs.

Mimosa, one of the dancers who worked with Wendy, calls Grissom and asks him to meet her at The Apple Martini. She's a transgender as well, and flirts with Grissom gently while she tells him about the opposition transgenders face in society. Mimosa tells Grissom that Wendy called her the night of her death and told her about the tape she had. She points Grissom in the direction of Dr. Mona Lavalle, Wendy's therapist, for answers.

In the lab, Warrick is going over evidence. Mia tells him she's identified the blood on Wendy's shirt as male, but not Wendy's. It could be the killer's.

Grissom and Brass go to Dr. Lavalle's house, where her husband Francis directs them to the backyard, where Lavalle is running a therapy group for transgenders and their spouses. Lavalle tells Grissom and Brass that Wendy came to her after she was denied surgery, and that they were working on her impatience issues. Wendy saw Dr. Lavalle the night of her murder to talk about her upcoming wedding.

Armed with this new information, Nick and Warrick trace Wendy's route from Dr. Lavalle's house to her home. But given the distances and the time Lavalle claimed to have seen her, they can't account for fourteen minutes. Nick puts it together when he realizes there's a storage facility in the vicinity, and that the second post-it note Sara found in the bathroom.

The CSIs go to the facility, where they follow bloody footprints to the locker on the note. When they open the locker, they are greeted with a gruesome sight: a dead woman, lying on an operating table, a victim of a botched gender reassignment surgery. Robbins examines the body and determines that the dead woman has scarring that indicates she underwent multiple surgeries. The woman died two days ago, and despite the grim circumstances, Robbins says the cause of death--massive loss of blood due to hemorrhaging--indicates it was accidental.

Catherine gets a bloody print off of the makeshift vaginal stretcher used in the botched surgery. Mia gets a skin sample from inside a latex glove found in the locker. Nick identifies the victim as Vern Saldusky, who used to work at a bar called The Cockpit Lounge. Grissom and Nick go there to question one of Vern's co-workers, Mercedes, whose own gender reassignment surgery was horribly messed up, leaving her trapped between genders. She tells them when she was turned down for surgery through the proper channels, she went to a Dr. Carl Venday, who performed the surgeries when legitimate doctors wouldn't. Vern went to him a few days ago.

All the evidence leads to Venday. Venday is a former Vietnam vet who used to perform illegal abortions. The CSIs can trace the abdominal retractor used in Vern's botched surgery to Venday, who apparently has no record with the American Medical Association and no medical license. Grissom looks at photos of Venday from Vietnam and a later photo from a protest and makes a startling discovery: Venday is Dr. Mona Lavalle.

The CSIs bring Lavalle in for questioning. She says she hasn't been Venday in years, and claims to have dedicated her life to helping transgenders have the surgeries they desire. Grissom shoots back that she doesn't have a medical license, and asks how many have died. She claims Vern was a tragedy, but that she didn't kill Wendy. She has an alibi: she was at her daughter's soccer game when Wendy was killed. When the CSIs go to search Lavalle's house, Francis is enraged at the invasion of their privacy. After Francis leaves, Nick gets a sample of his spit that was sprayed after his impassioned speech. Warrick finds a partially unraveled tape from a camcorder.

The DNA in the latex glove to Amber Hanshaw, Dr. Lavalle's daughter's nanny. She admits to helping Dr. Lavalle, who helped her turn her life around, but says she was at Lavalle's daughter's soccer game when Wendy was killed. Amber's alibi holds up as well.

Archie fixes the tape, which Wendy used to record what she saw in the storage locker. Warrick says she was probably trying to expose Lavalle. But if Lavalle and Amber both have alibis, that leaves only Lavalle's husband Francis. Brass has him brought in; it was he who was chasing Wendy after she made the gruesome discovery. He ran her off the road and killed her. He admits he tried to protect his wife's work, which he clearly believes in. But when the CSIs bring up the seminal samples on Wendy's mouth, he denies any infidelity. Nick posits that since he's a spitter, he may have transferred the sample if he had oral sex with his wife.

Grissom shares the results of the investigation with Mimosa, the dancer who used to work with Wendy. She's saddened to learn Wendy was killed by someone in the transgender community. Grissom consoles her suggesting that as oysters are able to switch genders, perhaps humanity only having one gender is the mutation.
