The Most Heartbreaking Delko Moment From CSI: Miami

Delko was a constant presence on "CSI: Miami" from the moment it arrived on the air. Despite a behind-the-scenes contract dispute making his Season 8 appearances rather sporadic, he returned in full-force for the final two seasons. After all, he was a key member of the Miami-Dade Crime Lab, so the show wouldn't have been the same without him. Still, this status didn't protect him from semi-frequent personal tragedy. Arguably the worst instance of this came in Season 4 when his sister and Horatio's wife, Marisol Delektorsky-Caine (Alana de la Garza), met her unexpected end.

The episode "Rampage" saw Horatio, Delko, and the rest of their team continue their brewing rivalry with the Mala Noche gang. Sadly for the former, the situation took a devastating turn when Marisol suffered a fatal gunshot wound courtesy of Mala Noche member Memmo Fierro (Robert LaSardo). Even though she shared in a rocky relationship with her brother (and was far from a unanimous favorite with "CSI: Miami" fans), next to nothing can compare to losing a loved one. Not to mention, it happened predominantly as a consequence of his and Horatio's jobs, adding guilt to their grief.

Horatio and Delko later brought Fierro and his boss, Antonio Riaz (Vincent Laresca), to justice, somewhat avenging Marisol's murder. Nevertheless, they couldn't do anything to bring her back or change what happened, and that's a kind of heartbreak that never fully heals.
