3: Crate 'n' Burial
Laura Garris has been kidnapped and buried alive. At the Garris' residence, Brass attempts to discourage Laura's husband, Jack, from paying the ransom, while Grissom and Nick analyze the tape-recorded message for evidence. Noticing a gap of silence and a low-frequency buzzing sound, they speculate that Laura is buried in the desert near power lines. Sara does a walk-through of the house and sees numerous signs of struggle. When Grissom joins her, he notices dirt on the bedroom carpet and a halothane-soaked handkerchief lying on the ground outside.

Grissom and Catherine are called to Lake Mead where the body of Wendy Barger is found floating in the water. Autopsy shows head trauma and signs of recent sex. Catherine calls Wendy’s husband, Winston, and the CSIs are surprised to learn that he did not report Wendy missing, although she was in the water for two days. They question him and learn that his marriage was on the rocks – the couple had not had sex for several months.
