A woman working at the Marc Jacobs store i n Soho received a strange package from California containing a white substance. She immediately called the police thinking it was the deadly poison anthrax. However when FBI agents arrived they later determined the powder was not anthrax but cocaine! WTF! The NYPD took the employee in for questioning, but no one was charged. "It appears to have been a huge mix-up," an inside source tells "Page Six." "The girl has no idea why she was sent it. The cops are looking into whether it was intended for someone else in the building. But she was not happy with how she was treated by the police and is considering filing charges." Can someone tell me why it is so easy to send cocaine through the mail. Thank you US Postal Service!
