Story summary

Brady Harmon, father of four children Harper (13), Hudson (11), and twins Gavin and Gracelynn (10), filed a lawsuit seeking $400 million from Saratoga County, the City of Mechanicville, two school districts, and a housing authority. The suit alleges negligence and systemic failures after his ex-wife Sarah Myers and her mother Amy Steadman poisoned and killed the children before taking their own lives on June 10, 2024. Harmon claims that Myers and Steadman had Munchausen syndrome by proxy, regularly drugging the kids with melatonin, Benadryl, and Kratom to control them. The toxicology report revealed lethal levels of diphenhydramine (active ingredient in Benadryl) and Mitragynine (a compound in kratom) in all six victims' bodies. Harmon expressed his profound grief and disbelief over the unimaginable harm inflicted on his children, sharing police reports on Facebook.
