Psychiatrist Says Mental Illness Led Yates To Kill

Testimony continues today in the Andrea Yates murder trial in Houston.

Testifying for the prosecution yesterday, a forensic psychiatrist said Yates was so ashamed after drowning her five children in the bathtub that she avoided her husband when he arrived home. Doctor Michael Welner said that's one of 60 examples that show Yates knew the killings were wrong. Among the others, he said, she made her husband think there was nothing wrong when he left that morning, then filled the tub and even removed the mat so the children would have no traction if they tried to escape.

Defense attorneys say Yates suffered from severe postpartum psychosis when she drowned her children. She has pleaded innocent by reason of insanity.

It's Yates' second trial on the charges. Her 2002 conviction was overturned.
