The stepmother of a New Hampshire girl who disappeared in 2019 at age five and is presumed dead has been jailed for at least a year and a half for perjury.
Kayla Montgomery, 32, pled guilty to two charges alleging that she lied to a grand jury about working at a doughnut shop on November 30, 2019, the day she claims she last saw Harmony Montgomery. 
She also agreed to cooperate with prosecutors who have charged her estranged husband, Adam Montgomery, with second-degree murder in the child’s death.

In exchange, prosecutors dropped charges that Montgomery lied to state health officials about having the child in her care in order to collect welfare benefits and that she received stolen firearms.
She did not speak at her hearing in Hillsborough County Superior Court other than to indicate that she understood the details of the plea agreement. 
Montgomery was sentenced to three and a half to seven years in prison, with one and a half years suspended and given as credit for time already served.
Her now-estranged husband, Adam Montgomery, has been charged with the murder of his daughter, nearly three years after her disappearance.

Although the five-year-old vanished around Thanksgiving in November, 2019, authorities Harmony were not made aware she was missing until November, 2021. 
In August, police announced that they believed she was killed in Manchester, New Hampshire  in early December 2019. 
Her father Adam Montgomery was charged in October with killing Harmony, then five years old, by repeatedly punching the disabled girl in the head, authorities allege.

Adam Montgomery pled not guilty to second-degree murder, falsifying physical evidence and abuse of a corpse. In exchange, prosecutors dropped charges that Montgomery lied to state health officials about having the child in her care in order to collect welfare benefits
Court records show that it was Kayla Montgomery who ultimately told authorities her husband had killed his daughter, then urged her to lie about the girl’s whereabouts to investigators.
The alleged ‘killer dad’ also faces charges of ‘altering, destroying, concealing, or removing’ his daughter’s body between Dec. 7, 2019, and March 4, 2020, and for tampering with a witness.
The search for Harmony was launched in November of 2021, after her biological mother, Crystal Renee Sorey, reported her missing to Manchester Police. 

She was sentenced to 3 and a half to seven years in prison, with one and a half years of the minimum suspended and given as credit for time already served.
Montgomery had been previously awarded custody of the child by a Massachusetts juvenile court judge, despite a lengthy and violent criminal history that included a conviction for shooting a man in the head during a drug deal in Haverhill.
Last month, police in New Hampshire released a video from an interview with Adam Montgomery after he was first arrested in December 2021, on charges of assault, interference with custody and endangering the welfare of his daughter.

As he was interrogated, the suspected child killer chain smoked cigarettes and at one point accused police of being out of line then later pointed out that they were painting him as a monster.
An investigation led by the FBI subsequently ensued – and led cops to arrest Adam Montgomery in January 2022, in connection with a second-degree assault charge involving his daughter prior to her disappearance.
He was charged with the murder of his daughter late October – nearly three years after her disappearance.
Harmony, who was blind in one eye, had lived with her father, and his convict wife Kayla, in the weeks leading up to her disappearance.
