Killer Chris Watts' mistress has revealed the chilling final message he sent her before he was caught.
The pair were having an affair before Watts brutally strangled his pregnant wife Shannan and smothered their two girls - aged three and four - in August 2018.
A series of texts between Watts and mistress Nichol Kessinger were revealed as police interviewed Watts, who was at the time playing the victim of a lost husband and father.
