“They were laughing just hours before…” 💔 Devastated father Mark Cotter says his last phone call with his four children gave him no sign that anything was wrong before they, their mother Lisa Cotter, and their grandmother were found dead. But it’s one handwritten letter left inside the home that investigators say may hold the answer to the entire tragedy

In a heartbreaking revelation that has stunned communities across the United States, Brady Harmon, a grieving father from Salt Lake City, Utah, has shared the final moments he spent talking with his four young children during what would become their last conversation. The children—Harper Harmon, 13, Hudson Harmon, 11, and 10-year-old twins Gavin and Gracelynn Harmon—were found dead alongside their mother, Sarah Myers, 44, and their maternal grandmother, Amy Steadman, in an apartment in Mechanicville, New York. Authorities believe the grandmother carried out a suspected mass poisoning, possibly driven by resentment over a recent custody arrangement. Harmon’s words paint a picture of innocent joy cut short by unimaginable horror, leaving a family shattered and a nation questioning how such darkness could unfold in an ordinary home.

Harmon, 46, described the roughly 15-minute FaceTime call on June 7 as filled with the kind of everyday delight that defines childhood. “They seemed like happy little kids,” he told reporters, his voice heavy with emotion. During that conversation, the children eagerly shared their latest drawings, showed off their pet cat, and proudly displayed something Gavin had built. Harper and Gracelynn beamed while presenting their artwork, Hudson laughed as he introduced the family cat to the camera, and Gavin excitedly demonstrated his creation. It was a typical, loving exchange between a father and his children separated by distance—one that now haunts Harmon as the final memory of their voices and smiles.

The father had not physically seen his children since 2019, but a recent court decision had granted him two months of custody starting July 1. He was preparing to fly to New York on June 30 to bring them home to Utah for an extended stay. “I was supposed to be flying out on the 30th, gathering my kids and flying them home, then having them there for 60 days,” Harmon explained. Those plans turned to ashes late Tuesday when police arrived at his door with the devastating news. The bodies of his four children, their mother, and grandmother were discovered in the apartment after neighbors reported concerns. The decomposition was so advanced that officers initially struggled to identify the victims.

Mechanicville Police Chief Bill Rabbitt revealed during a press conference that evidence, including a handwritten note found at the scene, “strongly suggests that Amy Steadman was involved in the deaths.” One child showed signs of being stabbed, while the others appeared to have been poisoned. Investigators recovered numerous prescription and over-the-counter medications, along with syringes, pointing to intentional poisoning. Sources indicated the act may have stemmed from Steadman’s alleged resentment after Harmon won recent custody rights. The grandmother had lived with the family at points during Harmon and Myers’ decade-long relationship.

Harmon spoke candidly about his former mother-in-law. “She was never really a cordial, warm person to be around… it was very arm’s distance,” he said. Yet she maintained a close, doting bond with the grandchildren, often spoiling them. This duality adds layers of complexity to the investigation, as authorities piece together motives and timelines. The note and circumstantial evidence have directed focus toward Steadman, though full results from the crime lab are still pending. Police continue to investigate, urging anyone with information to come forward.

The children’s deaths have sent shockwaves through Mechanicville and beyond. Harper, the oldest at 13, was known for her artistic talents, often drawing pictures she proudly shared with her father. Hudson, 11, loved animals and was excited about the family cat. The twins, Gavin and Gracelynn, brought energy and creativity—Gavin building things and Gracelynn sharing drawings. Old photos posted by Harmon on Facebook capture joyful moments: the children in butterfly and dinosaur Halloween costumes, playing on swing sets, and cuddling with their dad during naps on the couch. These images stand in stark contrast to the grim discovery in the Harris Avenue apartment.

Harmon’s pain is palpable. “They say time heals all wounds, but this is a gaping hole that will never heal… it will never go away,” he said, his voice cracking. He plans to bury the children in Utah, far from the site of the tragedy. “I don’t believe anyone who can’t protect them should be anywhere close to them,” he stated regarding his ex-wife, emphasizing his duty as a parent. The custody victory had represented a new chapter of hope, one now forever altered.

The family’s history adds context. Harmon and Sarah Myers shared the four children during a long relationship. Steadman, the grandmother, had been part of their lives at times. Neighbors described the household as quiet, with no obvious red flags. Yet the discovery of medications and a note has led investigators to suspect deliberate action. One theory involves rage or despair triggered by the custody change. Autopsies and toxicology reports will provide clearer answers in the coming weeks.

This tragedy highlights broader issues surrounding family separations, mental health, and child custody disputes. Experts note that while most custody transitions occur peacefully, high-conflict cases can escalate dangerously, especially when grandparents or extended family feel sidelined. Mental health professionals urge greater support systems for parents navigating divorce or separation, including counseling and monitoring for signs of distress. In upstate New York, local authorities are reviewing the case for any missed intervention opportunities.

Communities nationwide have responded with an outpouring of sympathy. Vigils, fundraisers, and messages of support have flooded social media. Many parents shared their own stories of custody battles, emphasizing the need for compassion and oversight. Schools in the area offered counseling to students who knew the children. The case has sparked calls for better coordination between family courts, child protective services, and law enforcement.

Harmon’s decision to speak publicly serves multiple purposes. It honors his children’s memory, humanizes the victims beyond statistics, and warns others about hidden dangers. “Harper and Grace would show me their drawings, Hudson would show me their cat and Gavin would show me something he built,” he recalled fondly. These small details paint a vivid portrait of lively, creative children whose lives were cut short. Their father clings to those memories as he faces an uncertain future alone.

As the investigation proceeds, questions remain about the grandmother’s mental state, access to medications, and any prior warnings. Police have not released the full contents of the note but confirmed it points to involvement. The community of Mechanicville, a small town known for its tight-knit feel, is reeling. Residents wonder how such horror could unfold undetected in a residential apartment.

For Brady Harmon, the road ahead is one of profound grief and responsibility. He must bury his children, navigate legal aftermath, and somehow find strength to continue. His story is a stark reminder that behind every custody case are real families, real children, and real emotions. The happy voices from that final FaceTime call echo as both comfort and torment. In sharing them, Harmon ensures his children are remembered not just as victims but as vibrant souls who deserved a long, joyful life.

The nation watches as this case unfolds, hoping for justice and greater awareness. Poisonings in domestic settings, whether accidental or intentional, expose vulnerabilities in everyday life. Families are encouraged to maintain open communication, secure medications, install safety devices, and seek help when tensions rise. For Harmon and countless others affected by sudden loss, the focus now is survival, remembrance, and healing—one painful day at a time.
