This horrible story is one of family annihilation. Chris Watts was having an affair and thought killing his wife, two daughters and unborn son would get him what he wanted; a new life? This case is from 2018 and you can find the documentary on Netflix “American Murder: The Family Next Door”  or look it up on YouTube. So many people did a great job in this case from Nickole Atkinson to the detectives to the polygraph examiner!
