Adam Montgomery Arrested In Harmony Montgomery Case

The father of Harmony Montgomery, the New Hampshire child reported missing two years after her last confirmed sighting, is under arrest.

Adam Montgomery, 31, was taken into custody on Tuesday in connection with his daughter’s 2019 disappearance, according to an announcement from the Manchester Police Department. The charges against Harmony's biological father include second-degree assault stemming from 2019 conduct with the missing child, interference with custody, and two charges of endangering the welfare of a child pertaining to Harmony Montgomery.

Last week, police received word of the child’s disappearance more than two years after she was last seen in Manchester in October 2019, as previously reported. Police Chief Allen D. Aldenberg called the delay “extremely concerning,” stating they hit the ground running when learning about the child, who was 5 at the time of her disappearance.

Authorities searched a Manchester residence on Sunday but did not go public with their findings.

Public Information Officer Heather Hamel confirmed with Oxygen.com that police responded to a call around the time Harmony was last seen.

“MPD did go to a home within the city in October 2019,” said Hamel. “And Harmony was there.”

Following Aldenberg’s initial assertions that investigators “don’t have many answers to many questions,” new information around how Harmony’s absence was discovered is coming to light. According to Fox News, Harmony was placed into foster care with her younger biological brother, Jamison, who was later adopted by married couple Blair and Johnathon Miller.

Harmony and Jamison had an especially close relationship, as per the Millers, who claimed Jamison still looks for his sister on the playground and calls out to her in the night.

“Harmony was the only thing consistent in Jamison’s life,” Johnathon Miller told Fox News. “Harmony is all Jamison had.”

The Millers hoped to reunite Jamison, now 5, with his older sister. But when the husbands returned to inquire about possibly adopting Harmony, the Massachusetts Department of Children and Families informed them that Harmony was back with her biological father, Adam Montgomery. 

Hoping to send holiday gifts to Harmony on behalf of Jamison, the Millers contacted the children’s biological mother, Crystal Sorey, who was unable to connect them with Harmony. The mother assumed Adam was deliberately driving a wedge between the young girl and her relatives, according to the Millers.

“All she thought was that Adam was keeping Harmony away from her and from Jamison because he just didn’t want them to have a relationship together,” said Johnathon Miller. “She told us that she had sent an email to someone at the local government level and that she was going to the courthouse and to the police. … And then she was able to contact Adam’s family, and that’s when they expressed concern that Harmony could be in danger.”

Jamison’s adoptive father, Blair Miller, a Washington D.C.-based anchor for Fox Nation’s “Crime Stories With Nancy Grace,” claimed the siblings spent years in and out of foster homes. The Millers credited Sorey for raising the alarm in her daughter’s disappearance after learning about it from the Millers.

Harmony’s whereabouts remain unknown.

“Although an arrest has been made, the search for Harmony Montgomery continues,” said the Manchester Police Department.

Adam Montgomery is scheduled for arraignment on Wednesday at the Hillsborough County Superior Court.

Harmony Montgomery would now be 7 years old. She’d be approximately four feet tall, 50 pounds, with blond hair and blue eyes. She is blind in her right eye and requires eyeglasses.
