Erin MacNeil

Erin MacNeil is the main villainess from "Live to Regret," episode 7.06 of Without a Trace.

She was played by Elisabeth Harnois.

Erin MacNeil is a bank manager and the wife of Larry MacNeil, and in the episode, the couple was attempting to have children. Erin's backstory revealed that she gave birth as a teenager, with her high school lover, Nathan York, as the biological father. Their child was given up for adoption, and in the events, Erin's attempt at pregnancy was done with hopes of fully becoming a mother. However, Erin also revealed that she has an infection that prevents her from ever having children; something she never told Larry.

Erin and Nathan's son was given up for adoption, and in the episode, Erin stole $100,000 from her bank, with plans to use the money to help her son. Sadly, when Erin arrived at the home of her son and adopted family, she was devastated to learn that he was killed in a car accident, so with that, Erin decided to give the money to Nathan to help his struggling art business. Nathan gave the money back, due to his wife's consternation over Erin contacting him. This prompted Erin to reveal the truth about the money, which started an argument that was shown early in the episode, with the shouting match ending with Nathan telling Erin never to contact him again.

Later on, Erin revealed her actions to her friend and co-worker Willa Conden, and she enlisted her help in putting the money back. Willa turned Erin down and pleaded with her not to go through with her plan, as she could be caught making such a transaction. Unbeknownst to Erin, Willa had known days prior that Erin stole the money, and she used that to steal money for herself, while her warning to Erin was an attempt to hide her own actions. Erin ended up kidnapped by Willa's boyfriend, Robbie, after Willa phoned him following Erin's departure, and in the end of the episode, Erin was rescued by police and later arrested by Samantha Spade.
