Claudine Sweeney (Stacie Theon) is the main villainess from Rosewood episode 2.14, "White Matter & the Ways Back" (airdate February 3, 2017). She is the assistant to Charles Furwell, the owner of a high-rise apartment building which, oddly, only had two tenants: Furwell's mistress, Alina, and Bobby Huff, who was found dead in an elevator.
Other than her duties as Furwell's assistant (which included serving as the voice of concierge Hala), Claudine was also a villainous thief; using her access to the building security system to steal from tenants. One of her victims was Huff, and she had stolen and sold his award for his work on a 1990s sitcom called, The Ways Back. Unlike her past robberies, Claudine was caught by Huff, who threatened to report her and expose Claudine's heel persona. To prevent this, the evil Claudine had Huff killed, doing so by rigging the elevator, causing him to be hurled to ceiling and breaking his neck.
Claudine was revealed as the killer and as Hala when she showed signs of congestion in their last conversation. She had caught a disease from Bobby's pet wolf, which caused a rash and affected her vocal cords. After the reveal, Claudine was handcuffed and arrested.
