He has just sold his car to pay his gambling debts. Todd321 turns out to be a man named Todd Baransky, but Todd hasn't struck it rich. While Horatio talks to her son Tyler, who tells the CSI that his mother is in trouble over mounting bills, Rebecca tells Calleigh and Ryan that she traded Dakota to a secretive man known online as Todd321 a month earlier. The CSIs question Rebecca Lamar, who also bet on Dakota. Kevin was involved in offshore gambling based on when celebrities die, and he made a hundred grand off Dakota's death.
When Horatio notices a "Death Pool" list, he becomes suspicious. A hit in IBIS leads the CSIs to Kevin Iverson, who insists his gun was stolen months ago. Alexx is able to determine that Dakota was shot in the water, and the casing from the fatal bullet is different from the one that killed Ethan.
DNA on the facial mask worn by Ethan's shooter leads the CSIs to Rodrigo Garza, one of the robbers, but Dakota's killer remains a mystery. Ethan was apparently killed for refusing to give up his jewelry, but Dakota, who was killed in the pool by a gunshot wound to the chest, gave hers up, making the motive unclear. Ice, jeweler to the stars, is hosting a party for his elite clients, but the soiree is interrupted when gunmen arrive to steal the bling and leave two people, Ethan Parker and the beautiful Dakota Hudson, dead in their wake. Following the lead of information, they carry out a dramatic operation involving FBI and National Treasury. They soon find that one of the victims is on the "Death Pool 100" list of a betting system based on the death of celebrities. The team investigates a suspicious double murder at the "Bling-Bling" party hosted by a famous jewellery designer in town.
