Mother and Granny Kill 4 Children in Murder-Suicide

Police say two women planned and carried out the drugging and killing of four children, then died by suicide.

Police Determinations: Four Homicides, Two Suicides

Mechanicville Police Chief William Rabbitt said the medical examiner ruled the deaths of Harper, Hudson, Gavin, and Grayson Harmon as homicides, and the deaths of their mother, Amy Stedman, and grandmother, Sarah Myers, as suicides. He delivered the findings at an August news conference and repeated that the ruling matched what investigators found in the home. That clarity sets the frame: four children were killed, and the two adults ended their own lives.

Police said Stedman and Myers worked together to plan and carry out the killings. Investigators also said no evidence pointed to any outsider at the scene, or any other participant. The working theory places all key acts inside the apartment, with planning and execution by the two women. That conclusion narrows the timeline and the who, and it aligns with common patterns in child homicide-suicide incidents involving caregivers.

Method Of Killing: Drugging And A Stabbing

Investigators reported evidence of intentional poisoning using prescription and over-the-counter medicines found inside the apartment. Police described drugging as central to the plot, and said one child suffered multiple stab wounds and showed defensive injuries. That detail suggests a struggle and a break in the planned method. It also explains why detectives weighed both the toxicology and the sharp force injuries when matching mechanisms to each victim.

Police said they found handwritten notes and other circumstantial evidence that tied Stedman to the acts. Detectives quoted from messages and letters that they said laid out planning and motive claims, even as they noted some claims could not be verified. As an evidence point, those writings supported premeditation and conspiracy, which prosecutors and judges often view as key in assessing intent and agency in a closed-scene event.

Toxicology Direction And The Substances Reported

On September 3 and 4, police said preliminary toxicology results were not inconsistent with their investigation and did not surprise them. That phrasing signaled that drug findings lined up with the poisoning theory. Reporting from a local outlet, citing sources, said the children’s blood contained diphenhydramine, the active ingredient in Benadryl, and kratom. Police did not release full lab reports publicly, but they affirmed the results fit the direction they had shared earlier.

Forensic toxicology in death cases can be complex because drug levels can shift after death. Specialists call this postmortem redistribution. That is why investigators often speak to direction and consistency rather than raw numbers in public briefings. The goal for detectives is alignment: do the lab calls, scene evidence, and injuries all tell the same story. In this case, officials said they did, across pills recovered, notes, and autopsy patterns.

No Outside Suspects, But One Open Detail On The Stabbing

Police said the deaths occurred fully within the apartment and that no outside person was involved. That claim reflects crime scene control, entry records, and phone and purchase histories that often close off third-party theories. Detectives did say they could not state which woman delivered the stabbing. That unresolved detail affects individual roles for that injury, but it does not change the homicide-suicide conclusion or the finding that both women planned the killings.

This case fits a wider pattern of child victim homicide-suicide carried out by caregivers. Studies show most such events are planned, and many are linked to family conflict, mental strain, or legal stress. Those patterns do not excuse the act; they help explain why planners often leave notes and why scenes often show a controlled setup before a final, violent act. Investigators treated those writings as context, while grounding their case in physical evidence.

What Common Sense Sees In The Evidence

The clearest facts point to planning, isolation inside the home, drugging with everyday medicines, and a final act of suicide by the two adults. That matches what police said and what the medical examiner ruled. The presence of a handwritten note strengthens the view that this was not a sudden rage, but a plan. From a conservative lens, the moral line is bright: adults hold duty of care. When grown-ups plot harm to children, the state must name it, and here the state did.
