The Sinister Story Of Adam Montgomery

On December 7, 2019, five-year-old Harmony Montgomery was fatally beaten by her father, Adam Montgomery, while the family lived out of a car in Manchester, New Hampshire. Her body has never been found. For two years, her disappearance went completely unnoticed by authorities.Harmony spent her early years bouncing between foster homes and her mother Crystal Sorey's care. Despite Adam Montgomery's extensive violent criminal record dating back to 2008, a Massachusetts judge awarded him custody in February 2019. An independent review later found that the state's child protection system failed to prioritize Harmony's safety.By November 2019, Adam, his wife Kayla, their two sons, and Harmony had been evicted and were living in a Chrysler Sebring. On December 7, after Harmony had a bathroom accident in the car, Kayla testified that Adam flew into a rage and repeatedly punched Harmony in the head while driving between stop lights. Harmony, who was partially sighted, was critically injured.Rather than report the death, Adam Montgomery launched an elaborate cover-up. Harmony's body was hidden in multiple locations: the trunk of a car, a duffel bag, a cooler, a ceiling vent at a homeless shelter, and a walk-in freezer at Adam's workplace. He purchased quicklime and rented a U-Haul truck to dispose of her remains — believed to be somewhere between Manchester, New Hampshire, and the Boston area.Crystal Sorey grew frantic in late 2021 after repeated attempts to contact her daughter failed. On New Year's Eve, police issued public appeals about Harmony's whereabouts. The search soon turned into a murder investigation.Adam Montgomery refused to attend his trial in February 2024. He pleaded guilty to falsifying physical evidence and abuse of a corpse but maintained his innocence on the murder charge. The jury convicted him of second-degree murder, second-degree assault, witness tampering, falsifying evidence, and abuse of a corpse.In May 2024, Judge Amy Messer sentenced Montgomery to 56 years to life in prison — consecutive to a 32-year sentence for unrelated gun charges. A prosecutor offered to reduce the sentence if Montgomery would reveal the location of Harmony's remains. He remained silent.Crystal Sorey has vowed to find her daughter's remains with or without his help. In May 2025, she reached a $2.25 million settlement with the State of New Hampshire. Montgomery's appeal is pending before the New Hampshire Supreme Court. Governor Chris Sununu called Montgomery "a monster who deserves to spend the rest of his life in prison."
