Some of Nicole Brown Simpson's personal treasures have been locked inside a trunk for 25 years and now her sister, Tanya, is opening it for Inside Edition. O.J. Simpson's ex-wife, Nicole, and her friend Ron Goldman were brutally stabbed outside her Brentwood, California condo in June 1994. For Tanya, Nicole's Swiss army watch is both precious and painful. “It’s the watch she wore the night she was killed,” Tanya told Inside Edition. A crime scene photo shows the watch on Nicole’s bloody arm.
