Missing Girl’s Father: 16 Years Of Crime In NH, Massachusetts

CONCORD, NH — When Christine Lubin stood on the doorstep of her apartment on Thursday and lamented her son-in-law and the father of a missing New Hampshire girl police are frantically searching for, was, at first, “a sweet guy,” but later, became “pure evil,” it was an emotional statement made by a woman with first-hand knowledge of the man her daughter was married to.

But the comment, while raw, may not be far from the truth.

A cursory check of court records and news reports in both Massachusetts and New Hampshire shows Adam Montgomery has a long, violent criminal history, often fueled by drugs, dating back to at least 2006, long before Harmony Montgomery, 7, one of his four children with two women, went missing.

At 16, while living on Donald Street in Bedford, he reportedly brought a weapon to a school in Manchester and was charged with felony possession of a dangerous weapon on school grounds. At the time, Bedford students attended high school in the Queen City. He skipped his court date which led to police attempting to search for him, according to news reports.

The reward for information about Harmony Montgomery's whereabouts was increased to $94,000 on Friday. Call 603-203-6060, 24 hours a day, seven days a week, if you have information about the case.

About a year later, in July 2007, Adam Montgomery was charged with burglary, simple assault, and curfew violation for being on the grounds of another Queen City school. He was accused of following a girl into her home on Plainfield Street in Manchester after accusing the girl of being in possession of his stolen cellphone on July 5, 2007. Adam Montgomery requested another girl he was with to punch the girl he was following — which she did, according to press accounts, with a closed fist to the face. He would enter a no-contest plea to the burglary charge, which was dismissed in January 2008. The school grounds incident occurred at Northwest Elementary School in Manchester. It is unknown what occurred there or how the charge was resolved.

A few months later, Adam Montgomery was charged with criminal threatening after pulling a knife on a former girlfriend, who was 15 at the time, in Bedford on Sept. 7, 2007.

Another boy was also charged with violation of a protective order for coming in contact with the girl. Adam Montgomery was held but released later on $5,000 cash bail after pleading not guilty in court in November 2007. His bail was revoked in March 2008 and the next month, he pleaded guilty, receiving a year in prison, a portion suspended, and probation.

Three weeks later, prosecutors made a motion to impose the suspended sentence, which was later withdrawn and a violation of probation charge filed.

On May 6, 2008, Adam Montgomery stabbed another teen in the leg and pushed him out of a moving vehicle in Manchester. He was charged with first-degree assault and reckless conduct charges, both felonies. A police prosecutor at the time told the New Hampshire Union Leader the incident was “a drug ripoff, of sorts,” with Adam Montgomery believing he was sold fake drugs. The prosecutor called the combination of weapons and narcotics "a recipe for disaster." Adam Montgomery was released on $25,000 cash bail and told the court he had no problem staying away from the victim.

“I don’t know who this kid is,” the newspaper quoted him as saying.

In January 2009, the criminal threatening sentence was amended and the reckless conduct charge nolle prossed, with Adam Montgomery being sent to prison for 383 days, according to court documents. He would also plead guilty to the stabbing charge and was sentenced to four years maximum sentence served concurrent with the amended threat sentence.

Drug Deal Shooting In Massachusetts

Five years later, Adam Montgomery went to a home on Cedar Street in Haverhill, Massachusetts, to score heroin and ended up shooting a man during the drug deal, according to the Lawrence Eagle-Tribune.

On Jan. 14, 2014, police were sent to the home for a report of a shooting. The victim was shot in the chin and the bullet exited the man’s left temple. He was taken to the hospital and later, recovered from the shooting.

During the incident, Adam Montgomery was also shot in the arm. Court records noted the same gun, a .38 caliber Taurus revolver, was used in both shootings. Police called it a drug deal gone bad, according to the report, with Adam Montgomery admitting he went to the home to score drugs and was jumped in an attempted robbery of the $280 he had. He shot the man but was dragged out of the building, beaten, and shot outside himself by the men who jumped him.

The U.S. Marshals Service later became involved in the search for Adam Montgomery, who was 24 at the time. They found him in Manchester and police assisted in arresting him. According to the Union Leader, he was taken to Elliot Hospital due to “pre-existing wounds.”

Adam Montgomery was charged with armed robbery, armed assault to murder, carrying a firearm without a license, and discharging a firearm within 500 feet of a building in Massachusetts in February 2014.

Months before the shooting, Adam Montgomery began dating Crystal Sorey and the couple conceived Harmony Montgomery, the missing girl, who is now 7, born in June 2014.

Nine months before the shooting, Sorey was living on Franklin Street in Haverhill, MA, mere blocks from the drug deal gone bad. A lien was placed on the home against her and another man, according to records, with a forced entry eviction occurring in April 2013.

In September 2014, Adam Montgomery pleaded guilty to the charges and was sentenced to 18 months in prison.

Sorey lost custody of Harmony Montgomery in July 2018, “due to a substance abuse issue,” according to her comments made to Manchester police last month. She also confirmed they both had substance abuse issues during this time period.

No court information was readily available about Sorey’s criminal or drug activity but she was charged with receiving stolen property, theft by unlawful taking-movable property, and purchasing, etc., alcoholic beverages by a minor in Pennsylvania, according to records, in June and July 2011.

Adam Montgomery later received custody of Harmony Montgomery from the Massachusetts Department of Children & Families sometime in 2018 or 2019.

Sorey, meanwhile, was working to gain her sobriety and after doing so, attempted to keep in touch with both her child and her father throughout 2019. She was living in both Devens and Lowell, MA, at the time. She accused Adam Montgomery and Kayla Montgomery of blocking communications by phone and social media apps, according to police.

Sorey said the last time she saw Harmony Montgomery was via Facetime in Easter 2019. She seemed “frightened,” Sorey told police.

Sorey contacting the police is what led to the current search for Harmony Montgomery.

Restraining Order At In-Law’s

Back in July 2021, Lubin also filed a restraining order against Adam Montgomery, according to court records.

Around 8 p.m. on July 2, 2021, her boyfriend accused Adam Montgomery of skulking around their home. After determining that it was him, while making eye contact, Adam Montgomery crossed the street away from the home, a report stated.

Lubin accused him of “passing back and forth across the street of my home” and called police. While waiting for the cops, her boyfriend spoke to a neighbor who claimed to have seen Adam Montgomery “tapping on the windows” of their home, a court document stated. Police arrived, spoke to all involved, and advised Lubin to file a restraining order, which she did.

Three days later, while going to get the mail, her boyfriend found a steak knife on the ground near where Adam Montgomery was accused of tapping on windows, the report stated.

Lubin said her daughter, Kayla Montgomery, and her three children had been at the home since March 21, 2021, after leaving Adam Montgomery due to “domestic violence on her,” a report said.

Lubin's restraining order was dismissed on Oct. 12, 2021, according to a court filing.

Assault Against Harmony Montgomery

Adam Montgomery’s family members accused him of assaulting Harmony Montgomery, after seeing the child with a black eye in July 2019.

Family members and Kayla Montgomery told police they last saw her around late October 2019. Adam Montgomery was living in a sober house at the time, she said, and then left the area to live in Maine with a third woman, police said. Sometime after that, they got back together. At the time, Kayla Montgomery accused Adam Montgomery of telling her that Harmony Montgomery was given back to her mother in Massachusetts.

Kayla Montgomery, state of New Hampshire investigators said, was collecting thousands in food stamp benefits for the missing girl the entire time she was not living with her or the father, which led to her arrest.

The reward for any information about the whereabouts of Harmony Montgomery was recently increased to $94,000. There is a 24 hour, seven-day-a-week tip line up and running at 603-203-6060, to take tips about the case.
