06E15 - Ambush

[Part 1] Students Bart and Duncan go fishing with explosives in the Everglades and accidentally find the corpse of Kathleen Newberry (the witness against Horatio's son Kyle bought-off by his mother Julia Winston) tied up in her drowned car. A fingerprint on the tape is from Julia's now suspiciously wealthy assistant Pamela Osborne. Someone switched the memory card with pictures on Calleigh's camera for use on laid-off CSI analyst Dan Cooper's website, exposing her allegedly systematic CSI bumbling. Delko and sergeant Frank Tripp trace Kathleen's stolen SunPass to trucker Ted Wallace. He says he found it in a toilet with traces of chloroform and the blood of ex-con Ron Saris, once Julia's fraud accomplice. After Horatio refuses Kyle's plea to let off Julia, she finds a legal way to get rid of her ex, all the way to Brazil. [Part 2] The Rio branch of the Mala Noche believed to enjoy executing Horatio, legally extradited on a false murder charge, in a manhunt, but he soon turns the tables and joins the hunt for Calleigh's kidnappers, who force her to clean what they planned to be her own murder scene, yet she manages to stay alive and give the team a crucial hidden clue.
