HOUSTON (AP) — A former Texas prosecutor has asked the state to pardon a woman who pleaded guilty in a 2004 car crash that killed her fiance, saying she now believes the accident was caused by a faulty General Motors ignition switch.

Candice Anderson was driving a 2004 Saturn Ion in November 2004 when the car suddenly veered off a road and ran into a tree in Van Zandt County, southeast of Dallas. Her fiance, Gene Mikale Erickson, who was 25, was killed. Anderson, then 21, was severely hurt.
