The case of Harmony Montgomery, a New Hampshire girl who has been missing for over two years and is now believed to have been killed in 2019, has been closely followed by people throughout New England. Complete strangers, even, have become so invested in finding the little girl that they volunteer for intense searches in wooded areas in Manchester.

The case has unfolded over the past eight months with frequent developments, many involving legal proceedings against Harmony's father, Adam Montgomery, and her stepmother, Kayla Montgomery.

Here's a recap of Harmony Montgomery's disappearance case, so far.

New Hampshire authorities are now treating the disappearance of Harmony Montgomery as a homicide.

Easter 2019: Harmony's biological mother, Crystal Sorey, told NBC10 Boston this was the last time she spoke to Harmony over Facetime.

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 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.

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. 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 investigate at the home on Gilford Street where Harmony was last known to have lived in Manchester for a second straight day.

Jan. 10, 2022: Manchester police said the multi-day search at the Gilford Street home was complete, and offered no additional details on what, if anything, was found, citing the ongoing investigation.

The amount of reward money on offers for information leading to the girl has reached $100,000 through donations.

Jan. 12, 2022: New documents reveal Harmony's biological mother’s emailed pleas for help in getting answers about her daughter’s whereabouts. Sorey begged for help in emails with the subject line, “my daughter is missing/in danger and dcyf wont help."

Police reports obtained by NBC10 Boston show 29 calls for service to the Gilford Street home where Harmony was last known to live between 2018 and 2020, including domestic incidents involving Adam Montgomery, Kayla Montgomery and other adults in the home.

Jan. 24, 2022: The New Hampshire Attorney General's Office said the investigation to date has narrowed the window of Harmony's disappearance to a period of under two weeks in 2019- Nov. 29 of 2019 and Dec. 10 of 2019.

May 4, 2022: A report concludes that Massachusetts officials did not consider the well-being of Harmony Montgomery "on an equal footing" with her parents' rights before releasing her into the custody of her father.

In the results of its investigation, the state Office of the Child Advocate said a lack of focus on Montgomery's needs compared to the rights of her parents, Adam Montgomery and Crystal Sorey, resulted in "significant placement instability for Harmony."

May 6, 2022: Kayla Montgomery is released on bail. She had been held on $5,000 bail since January, when she was arraigned on a welfare fraud charge.

"It's clear that she doesn't care about Harmony," Crystal Sorey, told NBC10 Boston in an exclusive interview. "She doesn't care to let anybody know where Harmony is."
