As the first responding officer at the scene of a bus crash, Patrol Office Ryan Wolfe impressed Horatio Canie enough to earn himself a chance to work with CSI. Benefiting from luck and timing, Wolfe was able to get his feet wet on a case very close to home, involving Calleigh Duquesne’s father, who is a suspect in a possible vehicular homicide. Wolfe immediately made it known that he is more interested in uncovering the truth than proving himself and by using traits already inherent in his character – intelligence, drive and sense of curiosity – he was able to put scientific knowledge into context and solve his first case. As a new CSI, Wolfe will not only have to prove he can do the job, he will also have to hill a spot once held by Tim Speedle, whose untimely death has rattled the tight-knit CSI team.
