Harmony Montgomery was missing two years before anyone noticed. Now her father has been convicted of murder

It’s been two years since Adam Montgomery was charged with the murder of his five-year-old daughter Harmony.

Now, he’s been convicted in the shocking case that sparked uproar across America over the horrific abuse the little girl suffered – and the mounting questions around how she fell through the cracks of the systems meant to protect her.

Harmony was last seen in the fall of 2019 in Manchester, New Hampshire, but for two whole years, nobody reported her missing.

At the time of Harmony’s disappearance, she lived with her father, stepmother and the couple’s two children. Harmony’s mother, Crystal Sorey, had lost custody of her daughter due to substance abuse problems.

When authorities finally began looking for the missing child in December 2021, they were two years behind the search.

Then, just six months into the missing persons investigation, the little girl’s father was arrested.

He was later charged with second-degree murder, tampering with witnesses, falsifying evidence and abuse of a corpse.

Authorities secured his arrest after his estranged wife, Kayla Montgomery, came forward, alleging her husband fatally struck Harmony in the head when she had a bathroom accident in the car.

Montgomery then placed Harmony’s body in a cooler, which he then snuck into his workplace freezer, before disposing of her remains at an unknown location in March 2020.

His attorneys had claimed during the trial that Harmony died under Kayla’s care and that Montgomery only went along with plans to hide the body to “protect” his and Kayla’s two infant sons.

On 22 February, Montgomery, 34, was found guilty on charges of second-degree murder, abuse of a corpse and falsifying information.

With his sentencing expected to take place this spring, here’s everything we know about the disturbing case:

Who was Harmony Montgomery?

Harmony was born in June 2014. At the time, her father was in prison before his release in 2015.

The little girl was removed from her mother’s care at least three times in the first four years of her life.

In July 2018, the Department of Child Services removed her from her mother’s custody, due to her drug addiction, and placed Harmony in a foster home.

Then, in February 2019, Montgomery was granted custody of Harmony before a review of his home was completed by the New Hampshire Division of Children, Youth and Families.
