Father Seeks $400 Million, Alleging Authorities Missed Warning Signs Before Four Children’s Deaths

The father of four children who were killed in Mechanicville, New York, has filed a legal notice seeking approximately $400 million from local government agencies and school districts, alleging that authorities failed to act despite repeated warning signs of abuse and neglect.

Brady Harmon’s September 10 Notice of Claim names the City of Mechanicville, Saratoga County, the Mechanicville City School District, the Ballston Spa Central School District and the Mechanicville Housing Authority. His attorneys allege negligence, civil rights violations and wrongful death, arguing that multiple agencies had opportunities to intervene before the children died.

The children were Harper, 13; Hudson, 11; and 10-year-old twins Gavin and Gracelynn Harmon. Police say they were killed on June 10, 2026, by their mother, Sarah Myers, 44, and grandmother, Amy Steadman, 64. The two adults later died by suicide. The bodies were not discovered until June 23 inside Steadman’s Mechanicville apartment.

One of the most significant allegations in Harmon’s filing involves an incident at school on May 29, 2024. According to the Notice of Claim, all four children became severely ill and displayed symptoms consistent with an overdose after reportedly being given Benadryl. Three were taken to Albany Medical Center, while one child was administered Narcan after appearing to suffer an opioid overdose. The filing argues that the episode should have triggered a more extensive investigation into the children’s safety.

The claim further alleges that authorities failed to adequately follow up on concerns involving the children, including their subsequent homeschooling and their medical treatment. Harmon’s attorneys contend that Child Protective Services and other agencies had multiple opportunities to investigate and potentially remove the children from what they describe as an increasingly dangerous environment. These claims have not been proven in court.

Toxicology results released earlier this month found fatal or lethal levels of diphenhydramine, the active ingredient in Benadryl and other allergy medications, in all six people who died. Mitragynine, the primary active compound in kratom, was also detected in four of the six. Police said one of the children suffered multiple stab wounds.

According to police, the toxicology findings were consistent with their determination that the four children’s deaths were homicides while the deaths of Myers and Steadman were suicides. Investigators have said their work remains ongoing.

Harmon’s attorneys argue that the tragedy was preceded by warning signs that should have prompted stronger intervention. They say the $400 million figure is intended to represent the scope of the alleged harm to Harmon and the children’s estates rather than a sum that has been awarded by a court.

The filing is only the first step toward a potential lawsuit. Under New York law, a notice of claim against government entities generally precedes litigation, and Harmon’s attorneys said a 90-day waiting period applies before a lawsuit can proceed. They also indicated that the filing may be amended as their investigation continues.

The agencies named in the Notice of Claim have been contacted for comment. The case could ultimately examine whether officials, schools and other agencies had sufficient information to recognize the alleged danger and whether their actions—or alleged failures to act—contributed to the children’s deaths.
