In one of the most disturbing family tragedies of 2026, four children were murdered by their mother and grandmother in a carefully coordinated act inside a small apartment in Mechanicville, New York. The adults then died by suicide. The case, which came to light after a neighbor’s welfare check, has revealed a timeline of deception, detailed planning, and a bitter interstate custody battle that left a father in Utah preparing for a long-awaited reunion that would never happen.

On the evening of June 23, 2026, Mechanicville police responded to a concern from a neighbor who had not seen the family for many days. Inside apartment M5 at the John S. Moore Homes on Harris Avenue, officers discovered the badly decomposed bodies of six people: 64-year-old Amy Steadman, her 44-year-old daughter Sarah Myers, and Myers’ four children — Harper Harmon, 13; Hudson Harmon, 11; and 10-year-old twins Gavin and Gracelynn Harmon. Identification was difficult because of the advanced state of decomposition. Autopsies later determined that the children’s deaths were homicides. One child had been fatally stabbed; the others showed signs of intentional poisoning involving over-the-counter sleep aids and prescription medications. The deaths of Myers and Steadman were ruled suicides.

Police Chief William Rabbitt later revealed that the killings were not spontaneous. Text messages between Steadman and Myers showed they had begun discussing the plan by June 5. Steadman visited multiple pharmacies to obtain sleep aids and medications prescribed to her. Internet searches linked to her devices included queries about drug interactions and the effects of certain substances. The women discussed the timing of the acts, how the children would be gathered, what they would be told, and how to reduce suspicion. Investigators believe the children were killed on June 10. Messages exchanged that day indicated the women were still communicating while the events were unfolding. One recovered exchange suggested the initial method was not working as expected with at least one child.

That same day, Sarah Myers sent a deceptively ordinary text to the children’s father, Brady Harmon, who lived more than 2,000 miles away in Utah. She wrote that the kids had “a little stomach bug” and were throwing up, and asked to move their scheduled video call to the following evening. Harmon, unaware of what was happening, replied that he would keep working and hoped they felt better soon. The next day he checked in again (“Are the kiddos feeling better?”) and attempted the video call. There was no answer. By then, according to police, all six people were already ᴅᴇᴀᴅ.

Harmon had last spoken with his children on June 7 during a 17-minute video call. He later described them as seeming like “happy little kids.” In the weeks before the tragedy he had been making detailed plans for their first extended visit in years. Under a court-approved parenting arrangement, the children were scheduled to spend roughly two months with him in Utah beginning July 1 — the first time he would have seen them in person since late 2019. He had asked Myers for information about their hobbies and interests so he could arrange activities, and he requested medical records so he could care for them properly. Myers responded with reᴀssuring messages about preparing for the summer.

Notes recovered at the scene painted a different picture. One note attributed to Steadman accepted responsibility and claimed the killings were the only way to keep the children safe from alleged abuse in Utah. Unsigned writings believed to be from Myers expressed anger at the Utah family court system and repeated similar claims of abuse. Police stated they could not independently verify those allegations. Harmon has strongly denied any abuse and has said the greatest harm done to his children was inflicted by the very people who claimed to be protecting them. In a lengthy Facebook post sharing the text screensH๏τs, he wrote that his children “were not pawns to be sacrificed when control was slipping away” and described them as four individuals with their own personalities, dreams, and an entire family waiting to love them.

The case has drawn attention not only for its brutality but also for the longer context of high-conflict custody proceedings. Harmon has said he spent years trying to maintain contact and eventually secured the summer parenting time. He also claimed that Child Protective Services in New York had received multiple reports about the household over several years, though most were determined to be unfounded. A contempt hearing related to the parenting plan had been scheduled around the time the bodies were found.

By early August 2026, police had publicly confirmed the dual roles of Myers and Steadman in the children’s deaths and the suicides of the two adults. The investigation remained open pending final toxicology results. Harmon had already brought his children’s cremated remains to Utah, where the family held a service and scattered the ashes. The text messages he released offered a stark window into the ordinary-sounding communications that continued even as the plan was being carried out.

The Mechanicville case stands as a grim example of how prolonged family conflict, isolation, and unchecked planning can end in irreversible tragedy. Four children lost their lives in what investigators have described as a deliberate and coordinated act by the two adults closest to them.
