(AP) — Authorities have arrived at the last known residence of Harmony Montgomery to investigate the disappearance of the New Hampshire girl. Authorities said Saturday that law enforcement agencies were working at a home in Manchester. Details have not been released. Harmony’s father and stepmother were previously arrested on charges related to her well-being. They have pleaded not guilty. Harmony vanished in 2019 at age 5 but was not reported missing until late last year. Police first became aware of the case when they received a call from the girl’s mother in November. She had been trying to locate her for months.
