A North Dakota mother slit her three children's throats in a frenzied attack before sending a chilling five-word text message to their father, police say.
Kailey Erhart, 22, allegedly stabbed her daughters Morgan, three, and Ava, five months, to death at her Mandan home on Thursday evening, according to an affidavit obtained by KVLY.
She also allegedly knifed her one-year-old son, Colton, but the little boy survived the attack after undergoing extensive surgery. Police say he sustained serious injuries.
Erhart carried out the 'horrific' attack after waving a gun at her estranged husband, Cameron, and chasing him and the children's grandmother out of the house with a knife, the affidavit said.
When police responded at the home, they said they found Erhart covered in blood and holding a kitchen knife to her own throat.
Officers found the three children lying on the floor after following a trail of blood to a nearby bedroom, the filing said. They were unresponsive and had wounds on their necks, per the document.
Before the attack, Erhart texted a video to Cameron warning him to 'say goodbye to your kids,' the affidavit said.
