Piers Morgan continued his gripping journey across the Atlantic to meet with some of America's most notorious female killers.

In the second episode of his Killer Women series, he met with mum-of-two Amanda Lewis who is serving life in prison for drowning her seven-year-old daughter Adrianna in a paddling pool.
What made this case particularly unusual, and chilling, is that the main testimony that got Lewis sentenced was from her own son AJ - who was just five years old at the time.
Viewers saw footage of a visibly upset AJ in the witness stand giving evidence against his mum - and it got them upset too.

They were very split in their opinions on whether someone so young could give reliable evidence - but then why would they make something like that up?
very strange that this woman was sent down purely on the testimony of a child. not the most reliable witness, it's a tough one #KillerWomen

He didn't recognise his own mummy at first? Awful! I wonder whether a 7 year old is really that credible ? #KillerWomen

People are saying how is this kid reliable but what reason would he have to lie #KillerWomen

I'm honestly shocked by this. Couldn't the boy have made up the story as a reaction to the trauma of his sister drowning?!?! #KillerWomen

A child couldn't possibly make something like that up..So perfectly described for someone who is so young, who is still a baby #KillerWomen

No way did she drown her own daughter. Children lie, it's what they do. #KillerWomen

The series has got people truly gripped, whatever they may make of the host and the controversial topics.
