Infamous mothers.
There was Susan Smith who strapped her two toddler sons in their car seats and pushed her car into a lake drowning them.
Another mother was Darlie Routier who stabbed her two young sons to death in her home while her husband and baby were asleep upstairs. Then she staged the scene and blamed an intruder. She now sits on Texas death row.
The tragic irony is... those babies last word was probably, mommy.
