Investigators dropped a camera into a sewer pipe and removed items Tuesday from an apartment where a missing 8-year-old girl’s father and his estranged wife once lived.

Officials said the focus was on a second floor apartment where Adam and Kayla Montgomery lived in 2021, WMUR reported.

Harmony Montgomery was reported missing in late 2021, but investigators quickly learned that the girl hadn’t been seen in two years, as CrimeOnline previously reported.

Her father, Adam Montgomery, had custody at the time she disappeared. No charges have been filed in Harmony’s disappearance, but Adam Montgomery was indicted on an assault charge that alleges he hit the girl in the face in July 2019. He has since been charged with multiple firearms charges, all unrelated to the disappearance.

Adam’s estranged wife, Kayla Montgomery, was indicted in March, charged with collecting Harmony’s benefits even though the girl wasn’t living in the household. Two months later, she was charged with receiving stolen firearms. Earlier this month, she was hit with a charge of lying to a grand jury.

According to WMUR, Manchester Police, the US Marshals Office, the New Hampshire attorney general’s office and the FBI all responded to the Manchester apartment building. The Manchester Fire Department set up an incident tent, while the city’s Department of Public Works dropped a camera into a sewer pipe while FBI agents watched the camera views from the utility truck.

Investigators were seen hauling a large refrigerator, wrapped in black plastic, out of the apartment, along with other items that were wrapped in brown paper.

Sources told WMUR that someone gave investigators new and credible information, leading to the search.

Investigators said they would likely be at the apartment throughout the evening but cautioned against speculating about findings.
