Speed dies in the Season 3 opening episode, "Lost Son", after being mortally wounded during a gunfight in a jewelry store. He and Caine brace themselves for a fight, but Speedle's gun jams giving one of the thieves an opportunity to shoot him in the chest. Caine calls for an ambulance, but Speedle succumbs to his injuries before help arrives, dying in Caine's arms. Speedle's death leaves the team, especially Caine and Delko, devastated. Internal Affairs is forced to investigate and Calleigh reports that the gun simply malfunctioned thereby closing the IAB investigation. A funeral is held and his parents and team are shown grieving over his loss. Speedle's position on the team was later taken by Ryan Wolfe, a former Miami-Dade Police Department patrol officer. During a first-season episode, Speed and Delko, during a night of clubbing on the town, were caught in a devastating and deadly fire when the nightclub bouncer set the building alight in a twisted effort to be a hero. Speedle was instrumental in saving lives when he noticed an emergency-exit door ajar, and he guided many victims to safety. Despite the trauma of the blaze, he insisted on working the scene with the rest of his team (season one, episode 22, "Tinder Box"). A few months after his death, Sara Piper a.k.a. Cookie Devine, (season 3, episode 18, "Game Over") fears a sex tape she made with her boyfriend will be leaked. She goes to the lab and ask for Tim Speedle, who had previously helped her (season 2, episode 24, "Innocent") and Horatio overhears. He steps in and informs her that Speed had been killed in the line of duty but promises to look into her case. Five years after Speedle's death, his memory is still tender in the hearts and minds of his colleagues. They have left his locker and effects intact, intriguing those who come after his demise (episode 6x04, "Bang, Bang, Your Debt").
