The toxicology report confirming the cause of death for an Upstate New York family was released on Friday, September 11, 2026. Mechanicville police identified the substances responsible for the deaths of a mother, grandmother, and four young children. The findings point to a deliberate act involving multiple toxic agents.

The report detailed the presence of kratom and diphenhydramine in the children’s systems. Diphenhydramine is an active ingredient found in over-the-counter medications like Benadryl. These substances were administered to the children, leading to their deaths.

In many ways, this report provides crucial answers to a case that has gripped the community. It confirms the method used in the tragic incident that authorities have classified as a murder-suicide.

The Investigation Unfolds

The victims were identified as mother Sarah Myers, grandmother Amy Steadman, and children Harper Harmon, 13; Hudson Harmon, 11; Gavin Harmon, 10; and Gracelynn Harmon, 10. The family’s deaths occurred in June 2026. Their bodies were discovered during a welfare check after neighbors reported not seeing the family for several days.

Mechanicville police initiated an investigation into the circumstances surrounding the deaths. Evidence collected at the scene played a significant role in shaping the initial conclusions. This evidence included a handwritten note, which authorities stated strongly suggested Amy Steadman’s involvement in the incident.

The investigation led authorities to believe that Amy Steadman and Sarah Myers conspired. Their alleged plan was to kill the four children before taking their own lives. This conclusion was drawn from the totality of the evidence gathered during the initial phase of the inquiry.

The Role of Specific Substances

The toxicology report specifically identified kratom and diphenhydramine as the substances used to poison the children. Kratom is a tropical tree native to Southeast Asia, and its leaves are known for psychoactive effects. Diphenhydramine is an antihistamine that can cause drowsiness and, in large doses, be fatal.

While Harper, Hudson, and Gracelynn were poisoned, Gavin Harmon also sustained stab wounds. This detail indicates an additional layer of violence in the tragic event. The combination of poisoning and physical trauma highlights the severity of the incident.

The use of these specific substances suggests a deliberate and calculated act. The presence of both a natural psychoactive substance and a common antihistamine indicates a planned method for incapacitating and ultimately killing the children.

Custody Battle and Motive

The incident occurred shortly before the children were expected to spend the summer with their father, Brady Harmon. Brady Harmon was engaged in a custody battle with Sarah Myers. This ongoing legal dispute provides a potential context for the tragic events.

Custody disputes can be highly contentious and emotionally charged. The timing of the deaths, preceding a scheduled summer visitation, suggests a possible link to the custody proceedings. Authorities continue to examine all aspects of the family’s life to understand the full scope of the motive.
