Police in Manchester, N.H., announced a dedicated tip line and a $12,500 reward for information leading to the location of a 7-year-old girl missing for more than two years, as Chief Allen Aldenberg made an emotional plea to the public during a press briefing Monday.
Harmony Montgomery was 5 when she was last seen in Manchester in October 2019. The New Hampshire Division for Children, Youth, and Families notified Manchester police last week that Harmony was missing, Aldenberg said Monday.
“Somewhere out there this little girl is in need of help, and that’s our job, and I need your help on helping us to find her safe so the next time we meet, maybe we meet with some good news,” Aldenberg said during the briefing, which was streamed by WMUR-TV.

Aldenberg said Friday that Harmony had been enrolled in a Massachusetts school, but he did not provide further information about her ties to the state.

Aldenberg said investigators have spoken with multiple family members but declined to share details because it could “compromise the investigation.”
“I’m not getting into the specifics of where she should have been or who she should have been with, other than to tell you that where she should have been and who she should have been with, she’s not with those people and she’s not at that location,” he said.
Aldenberg also announced a tip line dedicated to information on Harmony’s whereabouts. That number is 603-203-6060. Anyone with information also can call the Manchester Police Department at 603-668-8711 or the Manchester Crimeline at 603-624-4040.
Harmony is described as a 7-year-old girl standing about 4 feet tall and weighing 50 pounds, with blond hair, blue eyes, and glasses, according to a police statement.
It remains unclear why two years went by before Manchester police were made aware Harmony was missing.

“That’s a question I’ve asked that hopefully at some point along this I get an answer to,” Aldenberg said Monday.
“I want to focus on locating her now and dedicating all of our efforts to that,” he added. “If there was some flaw in the system — and I’m not saying there was — but if there was, where was it and how is it going to be addressed? That’s a very fair question, in my opinion, that hopefully we get an answer to.”
DCYF is assisting in the investigation by helping police piece together Harmony’s background, Aldenberg said.
The $12,500 reward is funded by $2,500 from the Manchester Crimeline and $10,000 from Manchester business owners Dick Anagnost and Arthur Sullivan, Aldenberg said.
Police searched a home on the city’s west side on Sunday, Aldenberg said, but he did not say if anything was found. Aldenberg emphasized that the current homeowner is not involved in the investigation and is cooperating with police.
Aldenberg said an “FBI representative” was part of the police department’s meeting on the case Monday morning.
“They’re filled in on the facts and the details and the circumstances of what we know now,” he said.
Aldenberg spoke directly to the camera as he pleaded to the public for any information on Harmony’s whereabouts.
“This is Manchester, New Hampshire, and this is a big city by New Hampshire standards, but it ain’t that big,” he said. “There’s a pretty tight-knit community at the end of the day [and] people need to do the right thing. I don’t think I’m asking a lot.”
