Update on the Investigation into the Disappearance of Harmony Montgomery, and Request for Assistance

Concord, NH – Attorney General John M. Formella, Hillsborough County Attorney John Coughlin, and Manchester Police Chief Allen D. Aldenberg provide the following update on the investigation into the disappearance of Harmony Montgomery.

The investigation to-date has narrowed the window of Harmony's disappearance to approximately November 28–December 10, 2019. According to information learned by police, Adam and Kayla Montgomery, together with their two common children and Adam's daughter Harmony, were evicted from 77 Gilford Street in Manchester on November 27, 2019. Multiple individuals have reported seeing Harmony with Adam and Kayla in the following days; however, by approximately December 6–10, 2019, Adam and Kayla apparently had only their two common children, and Harmony was no longer with them.

This information leads police to believe that it was sometime during this window of approximately November 28–December 10, 2019, that Harmony Montgomery disappeared. Witnesses have reported that during that time, Adam, Kayla, and the children were homeless and living out of cars, possibly in the North End of Manchester. One of the cars was a silver 2010 Chrysler Sebring, and the other was a dark blue 2006 Audi S4. Stock photos of these cars are attached to this release for reference; the actual condition of the cars in 2019 was worse than depicted in these photos. In addition, the Sebring's rear license plate was askew.

Manchester Police continue to request that anyone with information please call or text the 24- hour tip line dedicated to Harmony's rescue at 603-203-6060, in particular anyone who saw or interacted with Adam Montgomery, Kayla Montgomery, or the children during the time frame of approximately November 28–December 10, 2019, or who saw either of the vehicles in question during that time. Any information, no matter how small or insignificant it may seem, may contribute to the overall investigation.
