A mother murdered her five kids due to postpartum depression

Andrea Yates' ex-husband has condemned the criminal process the killer was put through 14 years after she drowned their five children in the bathtub of their suburban Texas home.

Russell 'Rusty' Yates, who has since remarried and has a son, slammed his ex-wife's murder trial, claiming it was the 'cruelest thing he had ever witnessed'.

He insisted her actions were 'completely a result of her illness' and maintains she was a good mother who loved her children.

The mother from Clear Lake, Texas, systematically drowned Noah, 7; John, 5; Paul, 3; Luke 2; and

Mary, 6 months, in their home in June 2001.
