The New Hampshire man convicted of killing his 5-year-old daughter was set to be sentenced Thursday afternoon.

Adam Montgomery was found guilty earlier this year of second-degree murder in the death of his daughter Harmony, whose body has never been found.

Police believe that the 34-year-old man killed Harmony in 2019, and then she wasn’t reported missing for nearly two years.

In addition to second-degree murder, Montgomery was convicted of second-degree assault, falsifying physical evidence, tampering with a witness, and abuse of a corpse.

The state is seeking a cumulative sentence of 56 years to life.

“This case involves the abuse, and murder of an innocent five-year-old girl at the hands of her biological father, Adam Montgomery, a defendant with an extensive criminal history for his age, and when so many earlier sentences tried to deter further criminal behavior using more than simply incarceration,” the state’s sentencing memo reads.

“Those sentences failed, leaving the Court little hope of rehabilitation,” the state adds in the memo. “Accordingly, for the charges upon which he has been convicted, the Court is left with few sentencing goals it can accomplish beyond deterrence and punishment.”

Montgomery attacked Harmony in the early morning hours of December 7, 2019, police said. He reportedly struck Harmony on her head and face because she had a bathroom accident.

Then several hours after the first attack, Harmony had another bathroom accident and Montgomery attacked her again, police said. This assault was far more severe, according to police.

“He only stopped striking Harmony when he felt something ‘different’ and acknowledged out loud that he believed he ‘really hurt her this time,’ ” the state’s memo reads. “Like the first attack, the defendant did nothing for Harmony after this second attack. Shortly after the second attack, the defendant realized that Harmony was dead and ‘folded her’ into a duffle bag.”

In the two years after Montgomery killed his daughter, he reportedly told witnesses that Harmony’s mother had taken her to Massachusetts and that he was visiting her. Montgomery promised officers that Harmony was alive and well, living with her mother.
