The father of a New Hampshire girl who hasn't been seen since 2019, but who police just recently learned is missing, has been arrested, police said Wednesday.

Adam Montgomery, 31, was arrested Tuesday on charges of felony second-degree assault, interference with custody and two misdemeanor charges of endangering the welfare of a child in connection with the disappearance of his daughter, Harmony Montgomery, according to police in Manchester.

The Manchester Police Department announced last week that it had just received a report that Harmony was missing, though she has not been seen since late 2019.

"The circumstances surrounding this prolonged absence are very concerning and are being thoroughly investigated," police said.

An affidavit filed Wednesday in Hillsborough County Superior Court said Harmony's mother, Crystal Sorey, called the Manchester Police Department on Nov. 18 and said she had not seen her daughter in at least six months. She later said she had not seen Harmony, who was in the physical and legal custody of her ex, Montgomery, since April 2019, when she saw her on a video call.

On Dec. 27, the New Hampshire Division for Children, Youth and Families reported to police that it was also unable to locate Harmony.

Investigators determined that Harmony had last been seen at a Manchester residence by police during a "call for service" in late October 2019, Manchester Police Chief Allen Aldenberg said during a news conference Friday.

Sorey told police that she and Montgomery both struggled with substance abuse issues, but she had since become sober and repeatedly tried to locate Montgomery and Harmony. The last time she saw her daughter, on the video call, she seemed frightened, Sorey told police, according to the affidavit.

Police on Friday found Montgomery sleeping in a vehicle with his girlfriend, the affidavit said.

"During our roadside interview with Adam, he made some contradictory statements during our interaction, which raised our suspicion and concern for [Harmony's] well-being," the affidavit said.

Montgomery had told an estranged wife, with whom he has other children, that he drove Harmony to Massachusetts to be with Sorey, but he told police that Sorey came to Manchester to pick the child up, the affidavit said.

When police asked Montgomery about Harmony's whereabouts, he said "not talking to you" and "I have nothing to say," the affidavit said.

The assault charge he faces stems from an incident in July 2019 in which he allegedly admitted to a concerned uncle that he gave Harmony a black eye after she failed to keep her little brother from crying, the affidavit said. The uncle told police that Montgomery admitted to him that he had "bashed" the 5-year-old "around this house."

Aldenberg said Monday during a news conference that the department was "operating under the assumption she’s alive and well and that’s how we’ll operate until someone convinces me otherwise."

"I’m in rescue mode. We are not in a recovery operation," Aldenberg said.

Late Tuesday, the Manchester Police Department said that, with help from donations from community members, the reward for info leading to finding Harmony totaled $33,000. The FBI also got involved with the case.

Hours later, police announced the arrest of Montgomery. He was due to be arraigned Wednesday, but the hearing was waived.

Montgomery was appointed a public defender Wednesday afternoon. A message to the New Hampshire Public Defender's Office was not immediately returned.
