Two women in the same Mechanicville, New York apartment murdered four children with allergy medicine and kratom before taking their own lives, police say.
Quick Take
- Police say mother Amy Stedman and grandmother Sarah Myers planned and carried out the killings of Harper, Hudson, Gavin, and Grayson Harmon.
- Investigators say the children were poisoned with over-the-counter medication, and toxicology later showed Benadryl and kratom in their systems.
- One child was also stabbed multiple times and had defensive wounds, according to police.
- Both women died by suicide, and police say no one outside the apartment was involved.
What Police Say Happened Inside the Apartment
Mechanicville Police Chief William Rabbitt told reporters the county medical examiner ruled all four children’s deaths homicides. Stedman and Myers died by suicide. Investigators said the two women “conspired to plan and carry out the killings” and found no evidence anyone else took part. The deaths happened entirely inside the family’s apartment, with no sign of an outside attacker involved.
Rabbitt said evidence recovered from the scene pointed to intentional poisoning using “numerous prescription and over-the-counter medications.” Reporters later learned more specifics. Sources told WNYT that completed toxicology reports showed both Benadryl and kratom in the children’s blood. Kratom is a plant-based substance sometimes sold as a supplement, and in high doses it can cause serious health problems, including breathing trouble.
A Stabbing Adds a Disturbing Second Layer
Police also revealed that one of the children was stabbed multiple times and had defensive wounds, meaning the child tried to fight back. WCAX reported investigators believe the children were first drugged before that attack happened. Police have said they cannot say for certain which of the two women physically carried out the stabbing, leaving that detail unresolved even as the overall homicide finding stands.
Investigators found a handwritten note inside the apartment. Police said the note, along with other circumstantial evidence, “strongly suggests” Stedman was involved in the children’s deaths. The note reportedly touched on family conflict, though police have not confirmed every claim it contained. Officials have described the killings as something the women planned in advance rather than a sudden act.
Toxicology Results Matched What Investigators Already Believed
By early September, police said preliminary toxicology findings were “not inconsistent with the direction of our investigation.” In plain terms, the lab results lined up with what detectives already suspected. Chief Rabbitt said the findings did not surprise his team, reinforcing the theory that the children were drugged before the stabbing occurred.
A Father Says Warning Signs Were Missed
The children’s father has said Child Protective Services sent him ten letters before his kids were found dead, raising questions about prior contact between the family and welfare officials. Police have not verified the abuse allegations that reportedly surfaced in family messages and the note, saying that part of the motive picture remains unconfirmed even as the homicide-suicide conclusion itself stands firm.
How This Case Fits a Larger, Grim Pattern
Researchers who study family killings have found that adults, usually parents, commit the vast majority of homicide-suicides involving children, and these cases are often planned rather than impulsive outbursts. Studies show these events are frequently tied to relationship conflict, mental health struggles, or legal disputes rather than one single clear cause, a pattern that mirrors much of what investigators have described in Mechanicville.
That broader research helps explain why police leaned on notes, text messages, and family history as context for motive, even while treating forensic evidence like poisoning and stab wounds as the hard proof of what physically happened. The Mechanicville case, tragic and rare in scale, still fits a documented and studied category of family violence.
What Comes Next
Chief Rabbitt’s department has closed the active threat portion of its investigation, saying the deaths were confined to the family and the case will not expand to outside suspects. Full toxicology and autopsy records have not been publicly released in detail, and any additional findings from the medical examiner’s office would likely come through future statements from local law enforcement.
