Adam Montgomery Arrives At New Hampshire State Prison, Will Serve 32.5 To 75 Years

CONCORD, NH — Adam Montgomery, who was sentenced Monday to 32.5 to 75 years in prison, has arrived at the New Hampshire State Prison for Men in Concord.

Montgomery was held at the Hillsborough County House of Corrections in Manchester since he was arrested and waited for trial. On Monday evening, he was transported to the prison and went through processing and intake. During the process, his prison photo was taken, which Patch.com obtained.

In June 2023, a jury found Mr. Montgomery guilty of two counts each of armed career criminal, theft by unauthorized taking, and receiving stolen property for stealing two firearms, a Mossberg shotgun and an AR-15 Bear Arms rifle, from a home in Manchester between September and October 2019. At trial, testimony was elicited about how Montgomery then negotiated the sale of the guns, one of which was later recovered. He agreed at trial he had requisite previous felony convictions that qualified him as an armed career criminal.

Outside the courtroom, Senior Assistant Attorney General Ben Agati took questions and explained how the sentence would be served. Montgomery will first serve 15 to 30 years for being an armed career criminal, specifically having the stolen shotgun. At the end of 15 years, he can request a parole hearing allowing him to begin serving the second 15 to 30 years.

Agati pointed out that until the parole board grants him parole on the first sentence he is not accruing time towards the additional 15 to 30 years.

After Montgomery begins serving the second sentence for being found guilty of being an armed career criminal, he can again apply for parole but must wait an additional 15 years.

After serving the back-to-back 15-30 year sentences, he can begin to serve the stand-committed 7½-15 years for the remaining charges with 5 years of that minimum sentence suspended.

In the aggregate, the defendant’s sentence mandates a minimum of 32½ years and a maximum of 75 years incarceration given the defendant’s extensive criminal history.

Agati thanked Manchester police.

“I appreciate the hard work of our trial team and the Manchester Police Department and thank them for their efforts in this case. I would also like to thank the court for the consideration and thought given in today’s sentencing. The Manchester community and all Granite Staters can be assured that we will continue to seek justice and protect the people of New Hampshire,” said Attorney General John M. Formella.

Montgomery’s next trial is scheduled to begin in November 2023 for charges related to the murder and disappearance of Harmony Montgomery. If found guilty, he could receive a sentence of life in prison without parole.

Two additional sets of firearm charges have not yet been scheduled for trial by the Court. If found guilty of the additional weapon charges he could receive an additional sentence of 10 to 30 years on each of the weapons charges.

Manchester Police Chief Allen Aldenberg thanked and praised all the hard work of the detectives and officers who have worked on the Montgomery cases. He also reminded everyone that Harmony, who was presumed dead, has not been located. He said he is confident there are people who have information that has not come forward.

The chief said now that Montgomery was spending 32.5 to 75 years in prison, people may feel safer coming forward.
