SAN DIEGO (AP) - A San Diego County woman has been ordered to stand trial for murder and assault in the drowning death of her 4-year-old autistic son.

The U-T San Diego says 36-year-old Patricia Corby of Carmel Valley sobbed often but never lifted her head during Wednesday's hearing in San Diego Superior Court.

Prosecutors claim Corby drowned her son Daniel in a bathtub, then drove him to a police station and told authorities she had killed him.

A district attorney's investigator testified he interviewed Corby after she was arrested and she told him she had no life because it was so entwined around her son's.

He said she told him she also tried to drown herself but failed.

Corby faces 25 years to life if convicted.
