A grieving father’s $400 million claim says schools and local agencies ignored red flags before four children were killed in a planned murder-suicide.

Story Snapshot

  • A Sept. 10 notice of claim seeks $400 million from five New York public entities.
  • The filing alleges the children were drugged and that officials missed clear warning signs.
  • Police ruled the deaths homicides and said the killings were planned over several days.
  • Investigators recovered handwritten notes and said abuse claims against the father were unverified.

The Legal Move: Who Is Accused and Why It Matters

On Sept. 10, Brady Harmon filed a notice of claim seeking $400 million from the City of Mechanicville, Saratoga County, the Mechanicville Housing Authority, and two school districts. The claim accuses these entities of negligence, civil rights violations, wrongful death, and medical abuse. The filing is a required step before a lawsuit against public bodies. It signals a fight over what officials knew, when they knew it, and what they did or failed to do before the children died.

The notice targets school and housing authorities as well as city and county offices. That approach suggests a pattern of contacts across classrooms, social services, and public housing settings. If school records, attendance notes, or nurse logs showed health or behavior changes, those could become central. So could any child-protection hotline calls or visits. Without the full filing and records, the public cannot see who had specific duties at key moments.

The Tragedy: Police Findings and Timeline of the Killings

Mechanicville police said the deaths were homicides. According to the chief, one child was stabbed and others appeared to have been poisoned. Investigators later said the killings were planned over several days and that handwritten notes were found. Those notes, reported by national outlets, pointed to a claimed motive tied to alleged abuse, which police said they could not independently verify. The planning timeline raises sharp questions about missed warning signs or chances to intervene.

The claim alleges the children were drugged before the final attack and that earlier overdoses in May 2024 sent three children to the hospital. Media summaries say the filing points to medication used to control the kids and argues authorities failed to act on those signs. These are serious allegations, but supporting hospital records and agency files have not been released publicly. That leaves a gap between the claim’s picture and documents the public can review today.

The Disputed Backstory: Abuse Claims, Custody Efforts, and System Response

Police and multiple reports say investigators could not verify abuse allegations made against Harmon, who has denied them. Investigators did recover handwritten materials and electronic files referencing abuse, but they said the evidence did not prove the claims. Harmon has said he spent years seeking custody or visitation and blames child-protection and family-court systems for failing his children. Those disputes frame the case but do not yet assign clear fault to any one office.

Local coverage says child-welfare officials had investigated the mother several times in past years, with findings that included inadequate guardianship and educational neglect, but no removal. That detail, if accurate, shows agency contact without decisive action. In failure-to-protect cases, liability turns on whether officials had actionable notice, power to intervene, and then failed to meet a legal duty. The coming records fight will likely focus on those exact points.

What To Watch: Records, Duties, and Accountability Across Agencies

The next phase will hinge on documents. The full notice of claim, school nurse and counselor notes, attendance patterns, internal emails, hotline logs, and hospital toxicology could clarify who knew what. If mandated reporters flagged danger and authorities screened out referrals, that will matter. If no clear notice reached decision makers, that will matter too. Both sides face incentives to shape the story as either systemic failure or unforeseeable family violence.
