'Darlie Lynn Routier, 40, of Rowlett is on death row for the June 1996 stabbing death of her 5-year-old son, Damon. She also was charged with killing his older brother, Devon, who was 6, but was not tried in that case. She has long contended that an unidentified intruder attacked them all, killing her boys and stabbing her, as well. Prosecutors say Routier killed her kids because they interfered with the lifestyle she wanted to live.

Andrea Yates, 46, of Houston drowned her five children in June 2001, believing she was protecting them from Satan. A jury found her not guilty by reason of insanity and she was ordered into a state mental hospital.'
