New Hampshire man convicted of killing daughter, 5, whose body has not been found

MANCHESTER, N.H. (AP) — A New Hampshire man was convicted of second-degree murder by a jury Thursday in the death of his 5-year-old daughter, who police believe was killed nearly two years before she was reported missing in 2021 and whose body was never found.

Adam Montgomery, 34, did not attend the trial and wasn’t present when jurors returned their verdict. He had proclaimed his innocence, saying in court last year in an unrelated case that he loved Harmony Montgomery “unconditionally.”

“I am grateful to the judge, jury, and Department of Justice for delivering justice for Harmony," New Hampshire Gov. Chris Sununu said in a statement. "Adam Montgomery is a monster and deserves to spend the rest of his life in prison.”

His attorneys earlier acknowledged his guilt on two lesser charges, that he “purposely and unlawfully removed, concealed or destroyed” her corpse and falsified physical evidence, but said he didn’t kill his daughter. The jury also convicted him of assaulting Harmony Montgomery in 2019 and of tampering with the key prosecution witness, his estranged wife and stepmother of his daughter, Kayla Montgomery.

Investigators believe Harmony Montgomery was slain in December 2019, though she wasn’t reported missing for almost two years. Kayla Montgomery testified that the body was hidden in the trunk of a car, a cooler, a ceiling vent, and a workplace freezer before Adam Montgomery disposed of it.

Adam Montgomery’s attorneys earlier said that he didn’t kill his daughter, and that the only person who knew how she died — his wife — was lying.

His defense attorneys did not immediately respond to emails seeking comment Thursday.

Adam Montgomery had custody of the girl. Her mother, who was no longer in a relationship with him, said the last time she saw Harmony Montgomery was during a video call in April 2019. She eventually went to police, who announced they were looking for the missing child on New Year’s Eve 2021.

Photos of the girl were widely circulated on social media. Police eventually determined she had been killed.

“We’ve still got to find her,” police Chief Allen Aldenberg said Thursday. “This girl deserves better than the life she had.”

Alendberg said he imagines the city of Manchester and state “probably feel pretty good right now that we, collectively as a state did our part on behalf of Harmony, and wherever she is right now, maybe she feels it.”

Kayla Montgomery is serving an 18-month prison sentence after pleading guilty to perjury charges related to the investigation into the child’s disappearance and agreed to cooperate with prosecutors. She testified that that her husband killed Harmony Montgomery on Dec. 7, 2019, while the family lived in their car after being evicted from their home.

Kayla Montgomery testified that her husband repeatedly punched Harmony Montgomery in the face and head because he was angry that she was having bathroom accidents in the car.

The couple noticed the girl was dead hours later when the car broke down, at which time Adam Montgomery put her body in a duffel bag, Kayla Montgomery had testified.

For the next three months, she testified, Adam Montgomery moved the body from container to container and place to place. According to his wife, the locations included the trunk of a friend’s car, a cooler in the hallway of his mother-in-law’s apartment building, the ceiling vent of a homeless shelter and a workplace freezer.

Prosecutor Benjamin Agati said at a news conference Thursday that the jury had to pay attention to 50 witnesses in eight days of testimony, thanking them for their time and attention.

Agati said the trial does not end the search for Harmony. He said that after analyzing the mileage Adam Montgomery took with the rental truck into Massachusetts, there are about 26 miles (42 kilometers) that he could have covered where her remains might be.

“She is somewhere along that route,” he said, pointing out previous searches in the Revere, Massaschusetts area. “Those are still our big areas of search.”
