Sierra LaMar Suspect Lawyer Steps Down
Thursday, Jun 7, 2012
Ken Mandel will no longer be representing Antolin Garcia-Torres, who has not yet entered a plea in answering to charges that he took Sierra on March 16.
The Santa Clara County public defender first assigned to represent the Morgan Hill man charged with kidnapping and killing 15-year-old Sierra LaMar is no longer on the case because of a conflict of interest, NBC Bay Area has learned.
