The charges filed by Manchester Attorney General John Formella accuse Kayla, 31, of receiving stolen firearms despite knowing or believing they were stolen.
The charges against Kayla come after her estranged husband and Harmony's father, Adam Montgomery, a career criminal with rap sheets in at least Massachusetts and New Hampshire, was hit with eight new gun charges last week related to the stolen firearms, on top of the allegations the man already faces, according to New Hampshire Attorney General John Formella.
Harmony was 5 years old when she was last seen in 2019, though police did not begin searching for her until December 2021 after learning that the girl had not attended school in the two years that Adam held full custody. They found Adam Montgomery living out of a car in Manchester, New Hampshire, on Dec. 31.
Investigators have not found evidence to link the stolen firearms to Harmony's disappearance, they said.
Adam, 32, and Kayla are being held on separate charges. Accusations against the father include child abuse for allegedly giving the partially blind child a black eye in 2019. Kayla Montgomery allegedly committed welfare fraud by collecting food stamps in Harmony’s name for months after she’d last seen the child.
After police questioned Adam Montgomery in 2021, they alleged he gave them contradictory statements – including first claiming to have recently spoken to Harmony and then backtracking to claim that the last time he saw Harmony was when her biological mother picked her up, sometime around Thanksgiving 2019.
Then he allegedly stopped answering questions and told investigators, "I have nothing else to say … If I’m not under arrest, I’m leaving."
He was arrested four days later. Adam waived his arraignment proceeding scheduled for last week in Hillsborough County Superior Court’s Northern District.
Harmony has not been found. The girl, who would now be 7 years old, is described as being 4-feet-tall and weighing around 50 pounds, with blonde hair and blue eyes. She would likely be wearing glasses and is blind in her right eye.
Anyone with information on her is asked to call the Manchester Police Department’s Harmony Montgomery tip line at 603-203-6060.
