Sheila Latham (Yaani King Mondschein) was one of the main villainesses from "Fallen Idols," episode 7.17 of CSI (airdate February 22, 2007). She was the best friend of high school cheerleader Megan Cooper, who was dating basketball player Ryan Lansco.
However, Sheila was revealed as one of a number of girls who slept with Ryan, who contracted crabs due to his promiscuity. Both Megan and Sheila had the STD passed to them, and regarding the latter of the two, she and Charlie Kellerman decided to crash the school's equipment shed--knowing that Ryan and Megan were there fooling around--and play a prank on Ryan. The duo tied up Ryan and forced him to admit on camera that he was carrying crabs and that women shouldn't be near him. Ryan later broke free and chased the pair in an attempt to get the camera, as Sheila stated that she planned to upload the video on YouTube.
Sheila and Charlie tossed the camera to each other before the former took out the memory card and put it on her tongue to taunt her. Ryan took the camera and tossed it at Sheila, striking her head and causing her to swallow the card. After Megan (and not Sheila, like Charlie said) unwillingly killed Ryan in a fit of rage, Sheila and Charlie placed the body in Ryan's van, covering up for the murder. When asked about Ryan and Megan's disappearance, Sheila refused to give details, all the while unaware that Megan was run down and nearly killed by teacher Diane Kentner, another of Ryan's lovers. After Sheila's cell phone was found on in the van, Jim Brass and Susan Latham (Sheila's mother), found Sheila on a sofa and attempted to wake her up, only to see that Sheila was dead, having died of epidural hemorrhaging, unwillingly caused by Ryan throwing the camera at her head.
