Harmony Montgomery’s father killed her, at least that’s what the 5-year-old girl’s stepmother told police in June, according to new documents.

Harmony Montgomery became the subject of a missing person investigation in New Hampshire after she disappeared around December 2019.

Soon after, her father and stepmother, Adam and Kayla Montgomery, were kicked out of their Manchester home and began living out of cars with Harmony and their other children.

That all changed in August when authorities said the case was now a homicide investigation, and became even more tragic on Monday when Adam Montgomery was charged with her murder. That same day, prosecutor Jesse O’Neill filed a document in another case against Adam Montgomery – in which the felon was charged with handling a firearm – that revealed some of the alleged statements made by his estranged wife. .

“During her June 3 interview, Kayla informed police that Harmony had been killed by the defendant in December 2019,” the filing states.

The filing was an objection to a defense motion to suppress a June 3 interview Kayla Montgomery conducted with Manchester police in which she was also charged.

Adam Montgomery’s defense attorney filed a motion to bar Kayla Montgomery’s testimony on Oct. 14. While the defense filing does not say what Kayla said in that interview, the filing says her statements “completely changed the landscape of gun cases.”

Monday’s filing added that “Kayla also stated that the defendant encouraged her on multiple occasions to lie to the police about Harmony’s whereabouts, essentially giving Kaya a ‘cover story’ and Told her that as long as she stuck to the cover story. Everything would be fine.”

Adam Montgomery, who faces charges of second-degree murder and tampering with a witness, along with charges of tampering with physical evidence and abuse of a corpse: Kayla Montgomery. He pleaded guilty to those charges and remains in prison. A pretrial conference on the firearms charge is scheduled for Thursday.

The statements not only color the cases against Adam Montgomery, but may also have some bearing on the ongoing welfare fraud case against Kayla Montgomery. Prosecutors allege that she listed Harmony as a dependent for about a year and a half after learning of Harmony’s disappearance in December 2019.
