Nina Reiser is seen in this 1999 California DMV photo.On a late summer day last year, Nina Reiser dropped her two kids off at her estranged husband's house in the Oakland hills and vanished into thin air. Prosecutors say that's because Hans Reiser killed her. His defense attorney says with no body ever recovered there's no case and suggests she may yet be alive in her native Russia. The unusual case begins, Monday, Nov. 5, 2007, when opening statements are scheduled.
