Coroner’s Report Reveals Mark Field’s Desperate Attempt to Save Mia, Harper, and Finn – Amid Questions Over His Escape and the Fire’s Rapid Spread

“Why did the father not get burned?” That’s the question haunting the Sanson community as police and coroners release new clues about Mark Field’s frantic final actions during the deadly house fire that claimed the lives of his three young children on November 8. The 38-year-old mechanic, who escaped with second-degree burns covering 40% of his body, has faced intense scrutiny since the blaze, with locals and online sleuths questioning how he survived while Mia (8), Harper (5), and Finn (3) perished upstairs. In a preliminary coroner’s report released Thursday, authorities clarified that Field’s injuries were consistent with a heroic but futile bid to reach his kids, amid a fire that spread with terrifying speed due to accelerants and poor ventilation. “Mark did everything a father could,” Detective Senior Sergeant Chris Lafferty said at a press conference. “The children did nothing wrong—this was a tragedy of circumstance.”

The fire, which gutted the Fields’ modest three-bedroom home on Taonui Road around 2 a.m., started in the garage from a deliberate act of arson linked to Mark’s undiagnosed mental health crisis. Toxicology cleared him of impairment, but the report details how he awoke to smoke and flames, kicking down the internal door in a desperate bid to reach the upstairs bedrooms. “He suffered burns to his arms and torso from crawling through the hallway,” the report states, “but the rapid flashover—intensified by petrol residues—blocked the stairs, forcing him back.” Field collapsed outside, neighbors pulling him to safety as flames engulfed the upper floor. Mia and Harper were found embracing in their shared room, Finn in the hallway with his hand outstretched toward the stairs.

The “why not burned” query arose from early photos showing Mark’s relatively contained injuries compared to the home’s total destruction. Forensic experts, including Fire and Emergency New Zealand investigator Dr. Elena Vasquez, explained the science: the garage blaze created a “chimney effect,” drawing flames upward while the ground floor remained cooler longer. “Mark’s path was low to the ground, minimizing exposure,” Vasquez said. “By the time he reached the stairs, the heat was 800°C – unsurvivable without gear.” CCTV from a neighboring property captured Field’s screams: “Mia! Finn! I’m coming!” before he tumbled out the front door.

Sanson, a rural enclave of 1,200, remains in mourning. Vigils have swelled to 800 nightly, with lanterns released at dusk per Chelsey Field’s wish to “turn tragedy into light.” The mother, 35 and pregnant, returned to the site Wednesday, laying flowers where her children’s rooms once stood. “They were my everything,” she told Stuff.co.nz, voice breaking. Mark, sedated in Palmerston North Hospital, faces manslaughter charges pending recovery; Chelsey has urged compassion: “Illness took my babies—not malice.”

The tragedy has spurred action. “Arnie’s Law” – named for a stolen-dog case that echoed the family’s pain – now includes mental health clauses for fire investigations. Donations to the Field Family Light Fund top NZ$220,000 for child safety alarms and counseling. “Sanson’s scars run deep,” Mayor Annette Money said. “But we’re healing together.”

As the coroner’s inquest continues, one truth endures: Mia, Harper, and Finn were innocent lights snuffed too soon. Mark’s “final actions” were those of a father undone by despair, not neglect. In Sanson’s quiet streets, their memory burns eternal – a call to protect the vulnerable before flames consume.
