Cynthia Chvatal

A mother thought to be grieving for the loss of her family three years ago becomes a suspect in a CSI investigation.

Some provocative episodes from Season 5 of CSI involve Russian mail order brides ("Nesting Dolls"), infantism ("King Baby"), and the Mexican lifestyle of narcocorrido ("Snakes"). From the creative storytelling ("4x4") to the macabre ("Who Shot Sherlock?"), there's something in Season 5 for everyone. The CSI team investigates many crimes that hit close to home as well. Grissom comes under fire from Ecklie ("Mea Culpa"), Brass tracks down his estranged daughter ("Hollywood Brass"), and during the course of the season Greg Sanders completes his transition from the lab to the field.

Season 11 of the hit drama CSI picks up where it left off - with Langston on the floor of a jail cell bleeding profusely - and ends with the team solving the mystery surrounding the explosion of a van during a funeral ("Shock Waves"). Future episodes contain grisly crimes involving a shark attack in the crowded pool of a casino ("Pool Shark") and the decapitation of a young man found in the woods ("Blood Moon"). Other cases involve the knife attack of a legendary vegas icon ("Sqweegel") and the CSI's reopen a cold case involving two young girls who went missing five years ago.

As CSI enters its 12th season, the team is still recovering from the fallout from the Nate Haskell case several months after its completion. Ray Langston has been let go and a new CSI supervisor, D.B. Russell, played by Ted Danson, has been hired. The Las Vegas crime lab also welcomes another new addition, a young CSI from Los Angeles and Ecklie's estranged daughter, Morgan Brady. The team must build new relationships as they solve cases that include a multiple homicide on a Vegas tram and a "Strangers on a Train" type case where numerous suspects who seem to be unrelated confess to murdering a family.
