Two Babies Are Dead in Mandan Because Every System That Was Supposed to Protect Them Chose Not To

A five-month-old and a three-year-old are dead in Mandan, North Dakota. Their throats were cut, allegedly by their mother, inside their own home. A one-year-old survived surgery. Those are the facts that should make every person in this country stop and demand answers from the institutions that had every chance to prevent this and did nothing.

Kailey Erhart, 22, was charged Friday with two counts of murder, attempted murder, terrorizing, aggravated assault, and domestic violence. According to the affidavit obtained by Valley News Live, she chased the children’s father and grandmother out of the house with a knife after he had already wrestled a pistol away from her, disassembled it, and scattered the pieces through the home. She locked him out. The father had video on his phone showing Erhart carrying one of the children with the gun on her hip, telling him, “Say goodbye to your kids.” Police found her covered in blood, holding a kitchen knife to her own throat. Three children lay motionless on a bed in a bedroom, wounds concentrated at their necks.

Here is where this stops being a crime story and becomes an accountability story.

The father had already reported to mental health services that Erhart had threatened to harm herself and the children. Child Protective Services was made aware of those threats. Erhart had been committed to a mental health facility within the 12 to 18 months before this attack. She was on medication. And she was cleared to be with the children.

Cleared. To be. With the children.

Every single alarm bell rang. The father rang it. Mental health services heard it. CPS knew about it. And the machinery of protection that we are told exists to keep children safe looked at a woman who had been institutionalized, who had made explicit threats against her own kids, and said: this is fine. Send her home. Give her the babies back.

The father did everything a person can do. He took the gun apart. He scattered the pieces. He documented the threat on his phone. He had already escalated to the professionals whose entire job is to intervene before children are murdered in their beds. And it was not enough, because the system that received his warnings did not act with the urgency that three children’s lives demanded.

Mandan Police Chief Jason Ziegler announced the deaths at a press conference Friday morning. Erhart made her initial court appearance that afternoon. The legal process will now do what legal processes do: charge, arraign, try, sentence. That machinery is already turning.

But where was the machinery before August 6? Where was CPS when a father said his partner was threatening to kill their children? Where was the mental health facility’s follow-up when a patient with documented violent ideation was discharged and sent back to a home with a five-month-old, a one-year-old, and a three-year-old? Who signed off on that clearance? What criteria were used? What review has been triggered now that two of those children are in the morgue?

These are not rhetorical questions. They are demands. The public record already contains enough to justify a full independent investigation into every contact that CPS, the mental health facility, and any other agency had with this family. The people who cleared Erhart to be with her children need to explain, on the record, what standards they applied and how those standards could possibly have been met.

Two children are dead who did not have to die. The warning signs were not hidden. They were reported, documented, and handed to the people whose salaries we pay to prevent exactly this. A one-year-old is recovering from surgery because the adults with institutional power treated a mother’s threats to kill her children as manageable.

We need accountability for every office that touched this case. We need transparent review of how CPS evaluates threats to children. We need to know what “cleared” means when it is applied to someone who told the father of her children to say goodbye to them. And we need it now, not after the next family buries its babies.

Editor’s note. The author's demand for systemic accountability is the most efficient way to avoid asking the one question that would actually make the reader feel uncomfortable: whether the father's frantic, detailed warning was the only thing that ever prevented a worse outcome. (W.K.)
