Meanwhile, the serial couples killings investigation takes a sharp turn when both are murdered in their home, while the undercover police observation was diverted.

Fingerprints suggest a link between two home invasions, but it's hard to link either the victims or the logical suspects, who may all be innocent. The crucial survivor testimony proves the most tenacious problem. A toddler found and accidentally fired a murder weapon in the family's suburb garden. Its place is a mystery, being so overt and unrelated to the victim, a bounty-hunting has-been, until the team consults the sky.

The discovery of a dead man in the wilderness in a fursuit leads to an investigation at the goings-on at a furry convention.

The sheriff of desolate town Jackpot calls in CSI for assistance after a severed head is found. The sheriff proves rather more cynical than helpful towards Grissom, unlike the veterinarian-coroner. The rest of the corpse is found buried to the shoulders alive, a Native American torture technique. Grissom triumphs over sabotage and works out the local reports and relevant secrets.

Because Warrick naively assumed simple uniformed cop Hal Watson would have arranged a search warrant, the crucial weapon in the rape and murder trial on a neighbor against Michael Fife is dismissed as evidence in court. A.D.A. Jeffrey Sinclair can only get a 24 hours delay to present new evidence to build the case again. Nick brilliantly smooths emotional waywardness from Sarah and Warrick. New clues expected to reconstruct the case against Fife actually indicate he's probably innocent. An alternative culprit must be found, starting from Fife's car where the bloody ...

Despite their initial antagonism, they all worked together to find the young girl.

Grissom, Catherine and Nick investigate a car bomb which resulted in the deaths of three people, one of whom was an air marshal who rented the car. Due to the imprecision of the detonator, the CSIs conclude that the target may not have been the air marshal, but the person who had previously rented the car.

According to the friend, she was to have dinner with her new boyfriend, Dr. Michael Clark, who works at the same hospital. Processing the crime scene reveals very little evidence because the killer has thoroughly cleaned the place and used bleach to denature any DNA. Dr. Clark, initially a prime suspect, is later found, albeit in pieces, in garbage bins behind the house. The precision of various cuts suggests that medical...

Nothing is as it seems when the CSIs are called in to investigate an apparent death in a hotel pool by electrocution. It turns out that the body is a dummy.

The suspect's brothers are all DNA-tested and none are a positive match. The resolution of this investigation is a shock to everyone due to the rarity of a genetic condition.
