Scuba Doobie-Doo

When the super Stu Evans brings two possible tenants to the apartment that was rented to Cliff Renteria and his girlfriend, he finds the walls covered in blood. Grissom, Warrick and Sara investigate the case and learn that Cliff left the apartment in the dawn and his girlfriend is missing. Cliff explains that the blood is from his nosebleed and he was revenging his landlord for the lack of services in his apartment. Meanwhile, Catherine and Nick investigate the mysterious case of a scuba diver found dead on the top of a burned tree by the firemen that were extinguishing the fire in the woods.

"Scuba Doobie-Doo" is another great episode of "CSI", with two storylines. The case of the blood in the apartment has many twists and is certainly the best one. The scuba-diver segment as entertainment is good. But technically speaking, I believe the 3,000 psi cylinder would have exploded with the fire surrounding with consequent raise of the temperature. My vote is eight.

Title (Brazil): "Scuba Doobie-Doo"

A couple of puzzles as usual. One involves an apartment where blood spatter is found all over the walls. How it got there is pretty interesting. But there is something else as Grissom follows the bugs. The other strange case has to do with a scuba diver found in a tree after a wildfire. Sometimes the stories get sort of beyond the pale, but they are always pretty entertaining.
