Villainous conspirator Leandra Cordero
Leandra Cordero (Susan Santiago) is a villainess from "Stoned Cold," episode 9.14 of CSI: Miami (airdate February 27, 2011). She is the mother of Nate Cordero, who was one of many students bullied by Blaire Hawkins.
Nate was one of Blaire's two main targets (the other being Megan Wells), and regarding Nate, Blaire tricked him into running out of the showers naked, which resulted in Nate being embarrassed and ostracized by his peers. After the incident, Leandra had acquired a recording of Blaire's victims detailing how they had been victimized, and she gave the recording to Amy and Kevin Wells (Megan's parents). The trio then decided to abduct Blaire and tie her to the goalpost in a plan to scare her into seeing the error of her ways. Blaire, believing it was a prank, heard Megan's voice and threatened to ruin her life, prompting Amy to toss a stone at her. After Blaire continuously insulted the trio and their offspring, the angry parents continuously tossed stones at Blaire, which ended up killing her. After the murder, Leandra, Kevin, and Amy placed the stones back in the pile and left the scene.
Megan and Nate were suspected in Blaire's murder, and after learning that her parents actually killed Blaire, Megan falsely confessed, leaving Nate out of it. However, the CD player revealed that adults actually participated in the murder, and after learning that Megan's parents and Nate's mother were the true culprits, Horatio Caine brought them to the police station, where he informed them that Megan and Nate were under arrest. This was only a ruse to get a confession out of the parents, which works. Their plan was only to scare her, but as Leandra put it, nothing was getting through to Blaire, and her cruel remarks led to the group killing her in a fit of rage. After the reveal, Leandra (along with the Wells) was arrested for Blaire's murder.
