Nikki Hallander (Law & Order: SVU)

Nikki Hallander (Natalia Payne) is the villainess of "Stranger", episode 11.10 of Law & Order: SVU (airdate January 6, 2009). 
Four years prior to the episode's events, Nikki pushed her sister Heather to her death from a roof, doing so in a panic that Heather would tell their parents about her using drugs. Sometime later, her mother found out what Nikki did, but chose to keep it a secret to avoid having to lose two of her daughters.
When Kristen Vucelik, an abused girl being held as a sex slave by her father, came to her home posing as Heather, Nikki immediately became vicious towards her, telling her offscreen that she knew she was an imposter and threatened to kill her if she didn't leave. Later, Kristen attempted to kill herself, which led the SVU squad to uncover her secret. When they told Nikki and her family, she almost exposed herself by saying she knew it all along (playing it off by saying she wasn't sure but simply noticed that "Heather" was acting strangely).
After being reunited with her mother, Kristen came to Nikki's mother and told her about Nikki's earlier threat, and the evil Nikki tried to take her to the same rooftop where she killed Heather and kill her as well, but the detectives arrived before she can and forced her to let Kristen come down. 
As Nikki confessed to her sister's murder, she started to climb up to the roof ledge, intending to jump to her death; however, after some negotiation, she surrendered herself to the police. As she was handcuffed, Nikki said to Kristen, "The police stopped looking for Heather a long time ago. Why'd you pick us?" before being led away by the police.
