MANCHESTER, N.H. – The story of little Harmony Montgomery's disappearance is laid out in 48 pages of a newly released court document. It's the foundation for the warrant on which her father Adam Montgomery is charged with second-degree murder.

"It's the same thing over and over and over again," said Anna Carrigan, a social worker with the New Road Project, which pushes for stronger child protections in New Hampshire.

What caught her attention was what allegedly happened near a Manchester restaurant two years before Harmony was reported missing. Her stepmother Kayla Montgomery told investigators the girl's father became angry over her bathroom accidents. She said he "delivered three-to-four blows with a closed fist to Harmony's face/head on three separate occasions…" She said he talked about it after, saying "I think I really hurt her this time. I think I did something."

"It's really hard not to go back and ask how this was not prevented when it seems like the breadcrumb trail was right in front of them," said Carrigan.

The warrant details how Adam Montgomery allegedly toted Harmony's remains across Manchester for about three months. First, in the trunk of a car parked outside an apartment complex, then moved to a cooler in his mother-in-law's home, and then to a shelter on Lake Avenue. According to Kayla Montgomery, he then moved the body to a refrigerator in an apartment they lived in on Union Street and even kept it in a walk-in freezer at a pizza shop where he worked on Elm Street.

Finally, MassDOT photos show a U-Haul crossing the Tobin Bridge in Massachusetts in March of 2020. According to Kayla Montgomery, that's when he arranged to have a U-Haul rented, allegedly disposing of the body.

Carrigan hopes Harmony's story reminds the public that there are others like her. "There are so many that we don't hear about, that the general public doesn't hear about, that are constantly happening. We've got to kind of just keep in mind that those are all going on behind the scenes," she said.

To this day, investigators have not found Harmony's body. Adam Montgomery's trial is set for later this year.
