Episode 192: The Devil She Called Dad: The Harmony Montgomery Case

Harmony Montgomery was just 5 years old when she was murdered by her father, Adam Montgomery, in Manchester, New Hampshire, in December 2019. Despite multiple warning signs of abuse and concerns raised by relatives, Harmony had been placed in her father's custody earlier that year. After her death, Adam concealed her body, which has never been recovered. Shockingly, Harmony wasn't reported missing until December 2021, when her mother, Crystal Sorey, realized she had not seen or spoken to her daughter in years.

During Adam Montgomery's 2024 trial, prosecutors argued that he fatally beat Harmony during a drug-fueled period of homelessness and then moved and hid her body for months with the help of his estranged wife, Kayla Montgomery, who later testified against him. Adam was convicted of murder and several related offenses in 2024, but in 2026 the New Hampshire Supreme Court overturned his murder conviction on procedural grounds and ordered a new trial. His convictions for abuse of a corpse, evidence tampering, witness tampering, and other offenses remain in place, and prosecutors have announced they intend to retry the murder charge. Harmony's body has never been found, and her case has prompted widespread criticism of the child welfare system for failing to protect her despite repeated reports of abuse.
