NEW YORK, Nov 24 (Reuters) - A Texas judge on Monday overturned the conviction of a woman who pleaded guilty to causing a fatal crash that killed her fiancé that was later linked to a faulty switch in the General Motors Co car she was driving, according to her lawyer. Van Zandt County District Judge Teresa Drum granted a petition from Candice Anderson to vacate her conviction for criminally negligent homicide, according to her lawyer, Robert Hilliard. Anderson was driving a 2004 Saturn Ion in East Texas with her fiancé, Gene Mikale Erickson, as a passenger when it veered off the road and hit a grove of trees in 2004.
