O.J. Simpson will retain custody of his two young children in a settlement with the parents of his slain ex-wife, his lawyer said Monday. The agreement, which still requires the signatures of Lou and Juditha Brown, heads off a second trial over the custody of 13-year-old Sydney and Justin, 10. “It’s in the best interest of the children that this not be dragged out through the courts any further,” said Simpson attorney Bernard Leckie. The Browns have long fought Simpson over custody of the children, but Leckie said Simpson is now on good terms with his children’s grandparents, and they’re closely involved in their grandchildren’s upbringing.
