O.J. Simpson agreed last month to give up custody of his two children to their maternal grandparents, according to a report by the Associated Press that cited court papers. Brooke Simpson, 8, and Justin Ryan Simpson, 6, have been living with Nicole Brown Simpson's parents since their mother's murder in June. O.J. Simpson has reserved the right to petition for their return if he is acquitted, according to the court papers. An attorney for Nicole Brown Simpson says the court will approve the change in guardianship in a few days.
