Manchester police and state investigators on Saturday returned to the West Side house that was the last known address of Harmony Montgomery, the little girl last seen in the fall of 2019 and reported missing in the last week of 2021.

The case of the missing girl has mystified police and captivated the state for more than a week. The Saturday search at 77 Gilford St. was the second search of the home in a quiet neighborhood of modest houses just off South Main Street, where Harmony, who was 5 at the time, was last known to have lived.

Investigators did not release additional information about the search Saturday afternoon.

Carloads of television reporters and photographers idled on the next block for most of the day. At nearby Francoeur’s Cafe, breakfast tables buzzed with talk of the case. Donations swelled a reward for information on Harmony to $94,000.

Harmony’s father and former stepmother were arrested late last week.

Her father, Adam Montgomery, was charged with assault, accused of giving the little girl a black eye in 2019. He had been granted custody of Harmony by a Massachusetts court, according to an affidavit in the case, as Harmony’s mother had struggled with a substance-abuse disorder. Montgomery’s estranged wife, Kayla Montgomery, was charged with fraud for collecting food stamps in Harmony’s name until June 2021.

A 24-hour tip line for information on Harmony remains open at 603-203-6060.
