Haunting update in case of murdered five-year-old Harmony Montgomery who's sick father's refused to say where he body is

Volunteers have gathered to search the north shore of Massachusetts for the remains of murdered five-year-old Harmony Montgomery.

Her killer father, Adam Montgomery, 34, was sentenced to 45 years to life in prison for the 2019 slaying of the little girl in New Hampshire.

He punched Harmony to death for soiling herself and has refused to reveal where he left her body.

Crystal Sorey, Harmony's mother, organized the Saturday search of Rumney Marsh Reservation where investigators believe Montgomery traveled in March 2020.

'That's the acceptance I've had to come to terms with in my grief, just accepting the fact that he's never going to do the right thing for her,' Sorey told WCVB.

'I've had a lot of dreams and this area has been in my dreams.' 

Although Harmony's remains were not found on Saturday, officials said they are focused on the route of a U-Haul Montgomery rented in March 2020.

They have been able to ping the vehicle's movements between Manchester and the Tobin Bridge in Boston using toll data. 

'Adam Montgomery drove 133 miles in the U-Haul truck. After accounting for 3.2 miles of back-and-forth travel with the rental, he covered approximately 106 miles on his route, including traveling through the Tobin Bridge tolls,' said New Hampshire Senior Assistant Attorney General Ben Agati.   

'He traveled northbound, southbound, and then northbound again through those tolls before returning to Manchester. This left him with about 26 miles of driving between the Econo Lodge in Manchester and the Tobin Bridge.

'Harmony's remains are likely somewhere along this route.'

Montgomery was convicted in February for Harmony's murder, as well as witness tampering, falsifying physical evidence and abuse of a corpse.

Prosecutors gave the killer one last chance to reveal where Harmony's remains are in exchange for the state recommending a lesser sentence, but were met with silence from Montgomery's attorneys. 

He was sentenced to 45 years to life in prison for the five-year-old's brutal murder, and he is serving a minimum sentence of 32 1/2 years in prison on unrelated gun charges.

Police believe that Harmony was killed nearly two years before she was reported missing in 2021.

A judge declared Harmony legally dead in March at the request of her mother.

Montgomery had custody Harmony. Her mother, who was no longer in a relationship with him, said the last time she saw Harmony was during a video call in April 2019.

She eventually went to police, who announced they were looking for the missing child on New Year's Eve 2021. Montgomery and his wife told police that he had taken his daughter to live with Sorey in Massachusetts. 

Harmony's stepmother, Kayla Montgomery, was released on parole in May after serving an 18-month sentence for perjury.

She testified that her husband killed Harmony on December 7, 2019, while the family lived in their car.

Kayla Montgomery said he was driving to a fast food restaurant when he turned around and repeatedly punched Harmony in the face and head because he was angry that she was having bathroom accidents in the car.

She said he then hid the body in the trunk of a car, in a ceiling vent of a homeless shelter and in the walk-in freezer at his workplace before disposing of it in March 2020.
