A suicide appears to be a murder with little evidence. Nick and Warrick compete to solve their 100th case to become a CSI level 3. Nick's case is a man who was drugged and robbed by a hooker and Warrick's is a murder where the killer claims self-defense. After Warrick breaks protocol to get a warrant, he is forced to babysit Holly Gribbs. The episode ends with the team celebrating Nick being promoted to CSI Level 3 when Brass comes in to inform them that Holly has been shot.
In the aftermath of the shooting that has left rookie CSI Holly Gribbs fighting for her life, there are big changes in store at the Vegas Crime Lab. Brass is sent back to Homicide while Grissom becomes the newly appointed head of the crime lab and is also in charge of the night shift. His first case is to investigate the supposed suicide of a jackpot winner with Nick. Meanwhile, Warrick has to deal with the fact that the shooting of Holly was due to his failure to supervise her, having abandoned
The search is on for Grissom, Nick, and Sara when an abducted woman is said to be buried underground. Meanwhile a hit and run death of a little girl is investigated by Catherine and Warrick, where the suspects are a 70-year-old man (John Beasley) and his teenage grandson who both seem to be covering for each other.
A woman's severed leg found in Lake Mead leads Grissom and Catherine to uncover a case of adultery. Meanwhile, Sara and Nick investigate a fraternity student's apparent suicide, but find out that the student's pledging has gone terribly wrong. Also, Warrick officially achieved CSI Level 3; however, he still remained under Judge Cohen's thumb, as he wanted him to tamper with the evidence related to a rape case, whose trial was in progress. Warrick, however, has other plans for the judge.
Grissom and Warrick investigate when a victim dies of fear in the desert, apparently from being chased; Grissom would later discover that the victim consumed an exotic tea containing jimson weed that was distributed at a rave. Meanwhile, Catherine and Nick investigate the gruesome murder of a Catholic school dean. Sara investigates how the body of a woman who was buried the previous week ended up in a dumpster, leading to an unscrupulous practice of "time-share coffins". (First appearance of Ass
Grissom and Nick investigate after a plumber discovered a skeleton of a woman under a house, buried in cement. Meanwhile, Catherine investigates a case in which her ex-husband Eddie is accused of rape. Warrick and Sara search for a missing bullet that could either exonerate or indict a cop for murder, though Brass was pressuring the team to hurry up with their investigation. (This is the first appearance of Coroner Dr. Al Robbins (Robert David Hall).)
When four members of a family are brutally murdered, two daughters are the sole survivors. The sheriff is anxious to provide the press with details, but hardly has anything to provide, as Grissom and his team are still examining the evidence. They suspect a cult murder, but the evidence tells an even more disturbing story. (This is the first appearance of Conrad Ecklie (Marc Vann), introduced as the Day Shift Supervisor of the CSI department.)
When another staged suicide takes place that was almost a duplicate of the "suicide" that took place in the pilot, Grissom realizes he is dealing with a serial killer who has a thorough knowledge of forensic science. The trail of evidence would lead to the same suspect - Paul Millander, who once again managed to stay ahead of the CSIs. Meanwhile, Warrick and Nick investigate a tourist's car that fell off a cliff, with the victim surviving his injuries - they would try to determine if it was an a
Grissom and his team investigate the death of a first class passenger on a flight to Las Vegas. Their investigation is a race against time, because after 12 hours the FBI will take over. To make matters worse, the other first class passengers are very reluctant to co-operate, leading the team to consider that they had some involvement in their fellow passenger's death. Note: Based on the events of Southwest Airlines Flight 1763, which happened August 11, 2000, not long before production of this
Grissom and Sara investigate when hikers found a body of a woman in the desert, covered with insects. Grissom uses entomological evidence to discover the time of death. Unfortunately their prime suspect - the husband - was out of town at that time, and to Sara's dismay, it looks like he is getting away with murder. Meanwhile Warrick and Catherine try to find out who stole a painting. Nick deals with a missing persons case when a woman's car is found at a bus station. Also: Ecklie informs Grissom
