Adam Montgomery Sentenced In Daughter's Killing: Reports

MANCHESTER, NH — Adam Montgomery, the Manchester father convicted of the 2019 murder of his 5-year-old daughter Harmony, was sentenced Thursday to 45 years to life in prison, multiple outlets have reported.

Montgomery, 34, was found guilty of second-degree murder, second-degree assault, abuse of a corpse, falsifying physical evidence, and witness tampering in February in connection with Harmony's presumed death.

"Justice has been served and Harmony Montgomery's memory and legacy remain our focus," New Hampshire Attorney General John M. Formella said Thursday. "Today’s sentence demonstrates that our legal system takes heinous crimes seriously and holds perpetrators accountable for their actions. The murder of an innocent child leaves a lasting scar on New Hampshire and our hearts go out to Harmony’s family and all those who knew and loved her."

Harmony is believed to have been killed in Dec. 2019 but not reported missing until more than two years later, prosecutors say. Her body has yet to be found.

During his most recent trial, Montgomery chose not to attend Hillsborough County Superior Court, though the jury was told not to consider his absence in their findings.

Opening statements in Montgomery's trial began on Feb. 8, Boston25 reported, adding that prosecutors said Montgomery told a friend that Harmony was evil.

"She was a constant reminder of her mother, Crystal, who he hated. He hated Harmony to his core," a prosecutor added, according to Boston25.

According to an affidavit obtained by WCVB, "Adam was extremely upset that 5-year-old Harmony was not saying when she needed to go to the bathroom and was having accidents in the car," Montgomery's wife, Kayla, told investigators.

Investigators believe that Montgomery fatally beat Harmony after she had an accident in his car on Dec. 7, 2019, WCVB reported, citing the affidavit.

After Harmony's death, Montgomery is accused of putting her body in a duffle bag and moving it several times, according to the affidavit.

He had been held in the New Hampshire State Prison for Men, serving two stand-committed consecutive sentences of 15 to 30 years for each charge of being an armed career criminal, followed by an additional consecutive stand-committed sentence of seven and a half to 15 years for the remaining charges with five years of that minimum sentence suspended.
