Part 2:

The last confirmed sighting of missing child Harmony Montgomery was in October 2019 when the Manchester Police Department in New Hampshire responded to a call at her home. She was only 5 years old at the time. After bouncing between living with a foster family and her mother, Crystal Sorey, for most of her life, a judge awarded her father, Adam Montgomery, full custody of her despite never fully verifying his employment or the safety of his home among other things. Just months after he was awarded custody, Harmony went missing. Unfortunately, an investigation into her disappearance wouldn’t begin until nearly two years later.

Authorities believe Harmony Montgomery went missing from the Manchester, New Hampshire area sometime between November 28th and December 10th, 2019. She would turn 8 next month, in June 2022. She is a white female with blonde hair and blue eyes. She does require eyeglasses to see as she is blind in one eye. When she went missing, she was about 4 feet tall and weighed approximately 50 pounds.

The reward fund for information about Harmony is ever-growing, but as of recording this episode it is up to $150,000. Anyone with information is urged to contact the dedicated tip line at 603-203-6060.
