NH v. Adam Montgomery: Weapons Trial

Posted at 5:05 PM, August 7, 2023 and last updated 6:58 AM, August 8, 2023


MANCHESTER, N.H. (Court TV) — Adam Montgomery was sentenced to spend at least 30 years in prison and up to 60 years on charges of being an armed criminal.

Adam, the father of missing Harmony Montgomery, was convicted of eight charges related to the 2019 thefts.

Addressing the court before the judge handed down his sentence, Adam denied he killed his daughter, the Associated Press reported.

“I did not kill my daughter Harmony and I look forward to my upcoming trial to refute those offensive claims,” he said. “I could have had a meaningful life but I blew that opportunity through drugs. … I loved my daughter unconditionally and I did not kill her.”

After hearing from both sides, Hillsborough Superior Court Judge Amy Messer sentenced Adam to at least 30 years in prison and up to 60 years on the charges of being an armed career criminal, the AP reported. He was also sentenced to an additional 7 1/2 to 15 years for receiving stolen property and theft.

Authorities accused Adam of stealing two firearms on two separate dates from the home of a person identified as C.F. in court documents.

At the time of his arrest in April 2022, Adam was in custody on assault charges related to Harmony’s case. Attorney General John Formella said in a news release, “There is no evidence of any connection between the stolen firearms and the disappearance of Harmony Montgomery.”

Prosecutors called Adam’s estranged wife, Kayla Montgomery, as a witness. Kayla is currently in custody on a felony charge of theft by deception for allegedly lying about Harmony’s whereabouts.

In Nov., Adam is scheduled to stand trial in the presumed death of his missing daughter, Harmony Montgomery. Authorities claim he 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 charges against Adam two months later. Investigators are still searching for her remains.
