CSI

The CSI team holds vigil at the bedside of one of its members who is shot in the line of duty and may not survive on the sixth season finale. Meanwhile, when evidence suggests that a small waisted man who was decapitated by a train was really a cover up for murder, the CSIs investigate the man's bizarre lifestyle of routinely wearing corsets.

Grissom is fascinated when every detail of a miniature is identical to that of a real crime scene, and he goes about trying to solve the case using the clues provided. Meanwhile, Catherine again finds herself--and someone close to her--in danger, and begins to suspect who may be responsible. Danny Bonaduce and Sean Young guest star.

While Grissom leads a group of college students on a tour of CSI, the dead "speak" while the CSIs investigate, each narrating their own case: a dead casino security guard whose luck ran out, a wife who "fell" off a cliff while hiking with her husband, a war veteran murdered on his first day back from Iraq and two neighbors whose encounter with a chainsaw ends badly.

When an innocent man is brutally attacked and beaten to death by what looks like a monster in a black cape, the CSIs are called to investigate, only to learn that a similar attack took place minutes later. As the crime spree continues, the team follows the trail of evidence until Greg interrupts a beating in action and must make a difficult decision that could impact his life forever. Kevin Federline and Victoria Recano guest star.

When a dead woman is found hanging from a cross inside a church, the team follows the evidence to uncover a bizarre love triangle dating all the way back to the victim's high school days.

When two young boys are reported missing, a known neighborhood sex offender is the primary suspect. In an attempt to extract his confession, Grissom asks for the pedophile's help in catching the boys' abductor. However, as the case unfolds, the crime turns out to be much more complicated than Grissom or the rest of the CSI team ever expected.

While investigating an elderly woman's murder, Grissom receives a miniature crime scene replica; Greg attends a hearing to ascertain his culpability in a teenager's accidental death.

When identical twins are found dead, the evidence in both cases does not immediately prove a connection between the two deaths. However, as the CSIs dig deeper into the histories of the women, a surprising twist takes the investigation in a new direction.

Grissom and his team investigate a string of murders in Las Vegas that may be tied to an infamous mob boss from the 1970s who disappeared many years ago. After the mob boss's Cadillac mysteriously resurfaces in a Las Vegas lake and a photo turns up of the murder victims posing with him in the 1970s, the CSIs begin to investigate whether or not the notorious gangster, whose disappearance remains a mystery, might somehow be connected to the current killing spree in Las Vegas.

When the CSIs process clues after a murder at a poultry manufacturing plant, the evidence leads them to the home of a man who collects miniature trains and other miniature paraphernalia. Grissom and his team rush to link him to the other miniature killings, but a twist in the case could prevent them from gathering enough evidence to catch the killer.

Catherine's testimony in court is not enough to convict a killer suspected of murdering his own mother. Adam Novak, with whom Catherine had a brief romantic encounter, is the lawyer who represents the killer and secures his freedom. As a result, Catherine and Nick leave Las Vegas in order to tie the killer to another crime and put him behind bars for good. Meanwhile, Grissom says goodbye to his colleagues and heads east for a teaching sabbatical.

As Catherine and Keppler begin to investigate the murder of a teen-aged "Jane Doe," both agree that the killer, who was meticulous in removing evidence from the body and its surrounding area, is likely a repeat offender. Soon they and the rest of the CSI team uncover three similar unsolved cases that suggest the serial killer has been active since 1975.

The lead suspect for the high-profile murder of anti-drug crusading assemblyman Danilo Zamesca is Thomas Simon, the west coast's biggest drug supplier. Simon's trail quickly grows cold, so Catherine agrees to Keppler's unconventional method to find him. Part of the plan involves withholding information from her team, and tension surfaces when the group senses something is awry.

A case involving a man's torched corpse whose bones and tissues had been harvested leads Nick and Keppler into the disturbing world of illegally sold human body parts. Meanwhile, Warrick and Sara learn more than they care to about the workings of a new-concept "host club" for women after discovering that a reportedly happily married murdered woman had been pursuing a "relationship" with Jesse, one of the establishment's most handsome and popular young hosts..

Grissom returns from his teaching sabbatical as new member of the team Michael Keppler desperately tries to keep his dark past hidden from his colleagues. As a result, he fails to disclose that he not only knows Frank McCarty (Len Cariou), the retired police officer who reportedly found the remains of his cop friend and a prostitute in a Las Vegas hotel room, but that Frank may have had a role in the murders.

With potentially less than a day to attempt to prevent the next murders, the CSI team must quickly shake off their shock that the true miniature killer is not the late Ernie Edward Dell, who committed suicide after confessing to the slayings. Grissom ponders why the killer deviated from his/her eerie tradition of leaving the miniature at the crime scene after the murder. He also laments that he held up the investigation by being on sabbatical when the unmarked package with the miniature arrived for him.

Grissom's quip that two missing young lovers may have run off to Mexico is soon quashed by the discovery of drops of blood by the boy's vacant parking spot at the high school. After finding a letterman jacket and cheerleading sweater in the field house and a pool of blood nearby, the team tries to determine what went awry.

While processing the house where several showgirls were murdered, Sara is haunted by the terrified eyes and cryptic dying words of the sixth victim she discovers.

In their attempt to identify the murderer of a has-been boxer who lived among a group of prostitutes who detested him, the CSIs must establish which of several life-threatening acts against him in one night actually killed him.

The CSI team investigates the murder of a blackjack dealer whose estranged husband has ties to a club of UFO believers. The CSIs discover that several suspects in a woman's murder are members of a bizarre UFO club who believe that shape-shifting reptile-like aliens have mated with humans for centuries as a means of conquering the human race.

Sara is uneasy about Grissom being reunited with Lady Heather during the CSIs' investigation of her attempted murder by a client she refuses to name.

As the CSI team comes closer than ever to identifying the miniature killer, Sara mysteriously goes missing, forcing her relationship with Grissom out into the open.
