Elliot Tramel Nowden, a homeless man with a history of violence against Metro train passengers, has been charged with murder in connection with the fatal stabbing of 66-year-old security guard Mirna Soza on Monday. Soza was returning home from her night shift at an Original Tommy’s hamburger restaurant when she was allegedly stabbed by Nowden on the Universal Studios train platform. Nowden was arrested shortly after the incident and faces life in prison without parole if convicted of all charges.
