Heather Crowley

Heather Crowley is the main villainess from "Broken Home," episode 5.16 of CSI: Miami.

She was played by Leighton Meester, who also played Jamie Martin in That's My Boy and Rebecca Evans in The Roommate.

Heather Crowley is the daughter of Kimberly and Edward Crowley, and also works as a babysitter for the Montalvos, as she was sitting for their young son Justin. Heather's parents' marriage was not a perfect one, as it was revealed that Kimberly was having an affair with Zach Griffith, Heather's boyfriend. She witnessed a confrontation between Edward and Zach, with the former telling the latter that he knew he was sleeping with her and to stay away from her, with Heather believing that she was the "her" they were arguing about.

After Zach killed Edward with his motorcycle helmet, Heather also witnessed Kimberly running to him, realizing that the men were arguing over Kimberly. An angry Heather confronted her adulterous mother, which ended with Heather killing Kimberly with a grill fork in a fit of rage. After her parents' murder, the evil Heather agreed to cover up for herself and Zack, and continued doing so by acting shocked when she found her parents' bodies during her babysitting job. In the episode's climax, a sexual examination of Kimberly's body revealed her affair with Zach, and it was Ryan Wolfe who interrogated Heather and revealed that she killed her mother. Heather confessed, stating that she couldn't believe that her mother would sleep with her boyfriend, and the episode's final scenes showed Zach and Heather arrested for the murders.
