MOAB, Utah -- A Utah woman accused of asking a Colorado motorist for razor blades after strangling her own daughter has pleaded guilty to a reduced count.

Wendy Bullock, 29, was charged with second-degree child abuse homicide in the toddler's January 2004 death. But Bullock reached an agreement with prosecutors to plead guilty to child abuse homicide while mentally ill.

Police said she drove into a pullout alongside Interstate 70 on New Year's Day, then asked a Colorado man in another car if he had any razor blades, because she planned to commit suicide. The man noticed that Bullock was injured and saw an unresponsive child in her car so he called police. Officers arrived to find the body of 2½-year-old Sarah Pollyanne in the back seat.

According to police, Bullock admitted strangling her daughter after they pulled off the Interstate to sleep. She said she was convinced that God wanted them to die. She stabbed herself in the eye with a sharp object and stuck a pencil in her ear before asking the Colorado motorist for razor blades.

Bullock, who was described as "the girl next door" by her attorney, will be evaluated at a state mental hospital before a judge decides whether she should remain there or be sent to prison.
