CSI Files sources released details about the seventeenth episode of CSI: Crime Scene Investigation's fourth season, which is currently untitled. Catherine, Nick, and Brass arrive on the scene, where they discover the body of a woman tied to the bottom of the bus, which is carrying inmates from a women's prison. It quickly becomes clear that the woman was dead before she was tied to the bottom of the bus. This wasn't an escape attempt--it was murder.

Grissom and Warrick have a case of their own--the stabbing of a young man named Adanto Adams. They learn that he was the brother of the man who lives in that apartment, "Zero." Zero is mentally disabled, but he has a guardian named Conrad Samuels, who has cared for him since Zero was fourteen. He tells Warrick that Adanto was a student at MIT and was extremely bright.

Grissom watches Dr. Robbins examine the body. Robbins reveals that the five stab wounds are all of equal depth, and progress from front to back. While Grissom examines the knife the killer used, Warrick talks to Zero, who tells Warrick that he was the one who discovered his brother's body. He also says that Adanto told him that he'd found a way to "beat" blackjack and cash in big time.

Nick and Sara pay a visit to the prison where the dead women, Antoinette Stella, was an inmate. Her roommate Kristeen, an angry young woman, is cagey but appears to have nothing to hide. Warden Hutton shows them Antoinette's locker, but there are no clues there, either.

Warrick heads to the casino where Adanto was planning to pull off his big scam. The pit boss appears unimpressed, and it seems that Adanto's scheme didn't go as planned. Grissom meets Warrick in the lab the next morning, and reveals that he's got a clean set of prints off the murder weapon...
