Dr. Leslie Harrison (Tamara Taylor) is a villainess from "Crime Wave," episode 3.07 of CSI: Miami (airdate November 8, 2004). She is a professor and a hurricane expert at a local university, as well as the lover of Steve Riddick.
Leslie was approached by Riddick regarding a plan to steal gold bars by using an oncoming hurricane in the heist. With that, Leslie participated in the villainous plot, taking a collection of inflatable GPS tagged bags and handing them to Riddick and his crew to use in the robbery. The plan hit a snag when a tsunami, not a hurricane, struck, and after the heist, Dr. Greismer (Leslie's colleague) was implicated, as he was a tsunami expert.
However, after learning that the robbers were preparing for a hurricane, as well as learning that Leslie was the only other professor with access to the bags, Horatio Caine took Leslie into custody, and she was interrogated by Horatio and Yelina Salas. Her relationship with Riddick was revealed, and she was informed that Riddick abducted Scott Riley, an employee at the bank who attempted to unleash his brand of justice to Riddick and employee/co-conspirator Farley Wheeler. Though she gave up Riley's location, the evil Leslie refused to reveal Riddick's whereabouts even after Riley was rescued by Horatio. After Riddick was captured, Leslie was arrested and informed by Horatio that he was planning on killing her, after he killed a pair of his partners. The villainess refused to believe Horatio's claim, stating that he's a decent man and he loved her, only for Horatio to rebuff Leslie's defense of her lover.
