North Dakota Mom's Chilling Threat Before Tragic Child Murders

A North Dakota mother accused of stabbing two of her young children to death ghoulishly told their father, “Say goodbye to your kids” in a blood-chilling video shot moments before the slaughter, according to a new affidavit.

Kailey Erhart, 22, is facing a slew of charges including two counts of murder, attempted murder, two counts of terrorizing with a dangerous weapon, three counts of aggravated assault and a misdemeanor count of domestic violence following the horrifying Aug. 6 incident at a home in Mandan.

Cops said she waved a gun at her estranged husband, Cameron, and threatened to kill herself before fatally stabbing their 5-month-old and 3-year-old kids, and savagely attacking their 1-year-old, who miraculously survived, cops said.
