Prosecutors say the woman and her husband had an argument in July 2010 at their Garden Grove home.

When he fell asleep that night, authorities say she tied him up, then woke him and cut off his genitals with a kitchen knife.

After allegedly throwing the body parts in the garbage disposal, Kieu called 911 and told police that her husband “deserved it,” according to authorities.
