Adam Montgomery charged with second-degree murder in death of daughter Harmony

Adam Montgomery was charged Monday for allegedly murdering missing daughter Harmony Montgomery.

At a Monday press conference, Attorney General John Formella stated that Montgomery was charged with second degree murder for allegedly repeatedly striking 5-year-old Harmony in the head with a closed fist causing her death around December 7, 2019. He is also charged for falsifying physical evidence and abuse of corpse for moving and/or disposing of Harmony’s body. Montgomery was also charged with tampering with witness or informants for allegedly causing Kayla Montgomery to lie.

Manchester Police Chief Allen Aldenberg, Attorney General John M. Formella, and U.S. Marshal Enoch Willard stated in August that they had multiple sources of investigative information including new biological evidence that Harmony was murdered in Manchester in early December of 2019.

Adam was previously arrested on January 4 in Manchester and was indicted on one charge of felony second-degree assault arising from 2019 conduct where he reportedly struck then 5-year-old Harmony Montgomery in the face. Montgomery was also charged at the time with one misdemeanor charge of interference with custody, and two misdemeanor charges of endangering the welfare of a child pertaining to Harmony Montgomery.

Kayla Montgomery, Adam’s estranged wife, was also indicted on the charge of Theft by Deception after allegedly receiving money through DHHS for Harmony when she wasn’t a member of the household.

The investigation had 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 Gilford Street in Manchester on November 27, 2019. Multiple individuals 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.

The information led police to believe that it was sometime during this window of approximately November 28–December 10, 2019, that Harmony Montgomery disappeared.

As previously stated by officials, Harmony once attended school in Massachusetts.

Adam Montgomery is scheduled to be arraigned on Tuesday on the new charges.
