Details of Disappearance

Harmony was last seen in Manchester, New Hampshire sometime in October 2019, when the police were called to her residence for unspecified reasons. This is the last confirmed sighting of her. She was not reported missing until late 2021, however, over two years later.

Harmony's mother, Crystal "Crys" Renee Sorey, notified police in November 2021 that Harmony was missing. Crys had lost custody of Harmony in 2018 due to substance abuse issues, and after she went into recovery and became sober she tried to contact Harmony. The child had been in foster care with her brother, until she was reunited with her father, Adam Montgomery, in February 2019. (Her brother was adopted by a family later that year.)

Crys was able to locate them and she had a video call with Adam around Easter 2019, and saw Harmony in the background, looking "frightened." This is the last time her mother saw her. After that, Adam blocked all contact, and Crys tried to locate her daughter for months without result. She said she had "a gut feeling that something is not right." She said she made repeated calls to authorities about her concerns for Harmony's welfare and had been ignored.

Police were initially unable to locate Adam. He was eventually found in Manchester, living in a car. Harmony wasn't with him and he said he had given her to the care of her mother around Thanksgiving 2019. This wasn't true, however, and Adam soon stopped cooperating with the investigation.

Harmony's uncle, Kevin Montgomery, said he had seen Harmony with a black eye during the summer of 2019 and asked Adam about it. Adam told him he had "bashed her around the apartment" after he left her unattended with her baby half-brother and came back to find her covering the infant's mouth to stop its crying.

Kevin said he had observed other behaviors by Adam that he thought were abusive, such as forcing Harmony to stand in a corner for four hours and telling her to scrub the toilet with her toothbrush. He said the family had made multiple reports to New Hampshire's Division of Children, Youth and Families (DCYF) and Adam cut off contact with them because of this.

In January 2022, Adam was arrested and charged with felony second-degree assault for abusing Harmony in the summer of 2019, and misdemeanor charges of interference with custody and endangering the welfare of a child for failing to report his daughter missing. He has a history of violent behavior and in was sentenced to 18 months in prison after shooting a man in the head during a 2014 robbery attempt.

A day later his wife, Harmony's stepmother Kayla Montgomery, was charged with one count of welfare fraud for obtaining $1,500 worth of food stamps on Harmony's behalf between December 2019 and June 2021, even though Harmony was no longer living with her and Adam.

Kayla and Adam have three children together. Kayla said the last time shaw saw Harmony was in November or December 2019, when Adam said he was going to take her to Massachusetts, where Crys lived at the time. He returned alone and Kayla never saw or heard about Harmony after that, and assumed she was safe in her mother's care.

Photos of Kayla and Adam Montgomery and Crys Sorey are posted with this case summary.

Authorities don't believe Harmony was enrolled in school at the time of her disappearance. She previously attended a school in Massachusetts. Her case remains unsolved, but police and her family hope she is still alive.
