Adam Montgomery, the father of missing and presumed dead Harmony, is charged in her death. He is scheduled to stand trial in November.

Authorities claim Adam killed 5-year-old Harmony in Dec. 2019. She wasn’t reported missing until Nov. 2021. In Aug. 2022, authorities said they believed she had been killed. They announced additional charges against Adam two months later. Investigators are still searching for her remains.

Earlier this month, Adam stood trial on charges of weapons theft. He was convicted of eight charges related to the 2019 thefts. Following the verdict, the Hillsborough Superior Court ordered the probable cause affidavit filed in Harmony’s case be unsealed 10 days later.

Key Takeaways From the Probable Cause Affidavit:
  • The affidavit was filed on Oct. 25, 2022
  • Adam Montgomery is charged with the following:
    • Second-Degree Murder
    • Tampering with Witnesses and Informants
    • Falsifying Physical Evidence
    • Abuse of Corpse
  • Harmony’s biological mother, Crystal Sorey, reported her daughter missing on Nov. 18, 2021. She told investigators she last physically saw Harmony, who was in Adam’s custody, during a FaceTime video around Easter 2019.
  • December 2021:
    • Adam’s wife, Kayla Montgomery, told investigators she last saw Harmony on Nov. 30, 2019, before going to work. That day, Adam told her he was taking Harmony to live with Sorey.
    • Kayla claimed she hadn’t spoken to Adam since mid-November.
    • Officers located Adam and his current girlfriend sleeping in a vehicle in Manchester. Adam “did not exhibit much emotion or reaction” to their search for Harmony.
    • A report from the New Hampshire Division for Children, Youth and Families (DCYF) indicated Harmony hadn’t been seen since Oct. 1, 2019, during a home visit with Adam.
  • Jan 4. 2022: Adam was arrested on assault charges for a July 2019 incident in which he allegedly struck Harmony.
  • June 3, 2022: Kayla was arrested on perjury charges for lying during her grand jury testimony, which took place on May 20, about her whereabouts the day Harmony disappeared. An investigation revealed Kayla was not employed when she claimed to last see Harmony before she went to work.
    • During a proffer interview with Manchester police and her attorney, Kayla admitted to lying.
    • She told investigators that their family was evicted on Nov. 27, 2019, and they began living out of their car.
    • Kayla claimed that on Dec. 7, 2019, Adam “struck Harmony, which caused her death.” She said Adam was upset that Harmony “was not saying when she needed to go to the bathroom and was having accidents in the car,” and “after each accident, Adam would strike Harmony in the face/head with a closed fist.”
    • Kayla claimed that after the fatal blow, no one sought medical attention for Harmony. Adam allegedly put Harmony’s body in a duffle bag when their vehicle broke down. They then went to live in acquaintance Anthony Bodero’s vehicle.
    • Two days later, the family moved in with Kayla’s mother. Kayla said they stored Harmony’s body in a cooler in the common hallway of the apartment building.

    • The family then moved to a shelter, where Adam allegedly stored Harmony’s body in a ceiling vent.
      • Detectives ultimately searched the area and located “staining” and “noted the area had a smell consistent with decomposition.”
      • A criminalist matched “all nine identifiable impressions” from the area to Adam’s fingerprints.
      • The area removed from the ceiling reportedly tested positive for DNA from Harmony.
    • Upon leaving the shelter, Kayla claimed they moved Harmony’s remains between an apartment they leased and Adam’s workplace while trying to “help with the decomposition of Harmony’s body.”
    • In the spring of 2020, Kayla claimed Adam and two acquaintances rented a U-Haul while they were staying in a hotel and used it to dispose of Harmony’s remains.
  • March 21, 2022: Anthony Bodero, an acquaintance of Adam, stated in his grand jury testimony that he let the Montgomery family live in his vehicle for two days after they were evicted. During that time, he did not see Harmony.
  • Jan. 5, 2022: Matt Gracia, a longtime friend of Adam, told investigators he and his girlfriend last saw Harmony on Thanksgiving 2019. During a December 2021 phone call discussing the news of Harmony missing, Adam allegedly told him; “(Harmony) wouldn’t stop pissing and (defecating) everywhere. She was driving me nuts. We were living in the car, so I let her, I had her mom come and get her.”
