Sorey lost legal custody of the girl in 2018 as she struggled with substance abuse issues. Harmony's father, Adam Montgomery -- who had legal custody -- blocked all contact. He was living in Manchester at the time.
Sorey, who lives in Massachusetts, said that she went on to call New Hampshire schools, drove by homes associated with her Harmony's father and made multiple calls to the New Hampshire Division of Children, Youth and Families.
October 2019: Manchester police, Harmony was seen during a Manchester police call for service in October 2019 at a residence in the city. This is the last time she was seen in Manchester, police said.
Dec. 31, 2021: Manchester police announce they received a report that Harmony Montgomery has not been seen since late 2019. "The circumstances surrounding this prolonged absence are very concerning and are being thoroughly investigated," the department said in a statement.
December 2021 - January 2022: Authorities search a home on Gilford Street in Manchester, New Hampshire, multiple times, which they said in a news release "is a focus of the investigation because it is the last location where Harmony was known to reside before her disappearance in 2019."
Jan. 4, 2022: Harmony's father, Adam Montgomery, is arrested on charges including failing to have Harmony in his custody. He pleaded not guilty.
Jan. 5, 2022: Adam Montgomery's wife, Harmony's stepmother, is arrested, accused of welfare fraud for allegedly collecting food stamps for the girl even though she was no longer living with the couple. She pleaded not guilty.
Jan. 8, 2022: Speaking first to NBC10 Boston, in her first public comments since the mysterious disappearance, Sorey had this message for her 7-year-old girl: "Hi, baby. If you can see me and hear me, I want you to know that I never stopped looking for you and I won't stop fighting until I find you, okay? You stay strong and mommy's right here fighting for you. I love you!"
Jan. 9, 2022: Police were out investigating at the home on Gilford Street where Harmony was last known to have lived in Manchester for a second straight day.
Investigators brought specialty equipment to the home as part of the ongoing investigation into Harmony’s disappearance. A ground heater was seen parked in the home’s driveway; machinery typically used during winter months to help thaw soil. Crime tape sealed off the sides of the home that lead to the back yard.
It’s unclear what investigators have uncovered and recovered from the property.
Police have established a dedicated, 24/7 tip line that members of the public can call or text with information about Harmony’s whereabouts. They reiterated their plea to call or text the it at 603-203-6060.
Nearly $100,000 in reward money has been made available for information on where she is.
