Investigators said they are searching for Erika Cooper, 34, aka Bianca Williams, after she stole the diamonds from client Kurt Kaiser's room at the Cosmopolitan Hotel April 17, the New York Post reported Thursday.
Police said Cooper was recorded fleeing by a security camera and she gave Kaiser her real phone number, which allowed them to identify her from mug shots taken after a previous prostitution bust.
Kaiser, a gem trader, said he has two partners who were also affected by the theft. He said he suspects he was drugged by Cooper.
