A dad arrested last month over the disappearance of his young daughter who was last seen alive in 2019 is also suspected of a brutal 2008 murder.
Adam Montgomery, 31, is considered a suspect in the February 2008 killing of Darlin Guzman, a 28 year-old computer repairman, it was reported Thursday. Guzman was shot and killed in the parking lot of a convenience store in Lynn, Massachusetts.
Guzman was heard arguing with a man moments before he was killed, Boston25 reported. No-one has ever been charged over his murder, and no motive has been given – although the dead man’s relatives said he’d planned to meet with Montgomery for an unknown reason.
One of Guzman’s sisters on Thursday reacted to the news, calling Montgomery a ‘monster’ and stressing that the focus at this time should be on finding his missing daughter, DailyMail.com can reveal.
Montgomery was arrested last month on multiple counts related to daughter Harmony’s disappearance two years ago when she was five, including assault and child endangerment. He pleaded not guilty and has been jailed in New Hampshire without bail.
Montgomery has refused to talk to the police about the whereabouts of his daughter, who was in his legal custody when she vanished.

On February 10, 2008, Guzman, a father-of-three computer repairman, originally from the Dominican Republic, was fatally shot in the parking lot of a convenience store in Austin Square.
Emad Abedeldin, the owner of the the store, Austin Square White Hen Pantry, told the Daily Item at the time that he heard Guzman arguing with another man before gunshots rang out.
Guzman was shot in the chest and later died at a hospital.
Police at the time described the gunman as a light-skinned man in his 20s, standing at about 6 feet tall, wearing a red hooded sweatshirt. He was last seen driving a red Honda Accord towards Saugus.
Boston 25 reported, citing the police source, that Montgomery and two members of his family, who have not been named, have been considered persons of interest in the murder investigation for more than a decade.

Montgomery was 18 years old at the time the killing. He was facing several unrelated criminal charges and was free on bail when Guzman was murdered.
According to the authorities, Montgomery and his relatives had been in contact with Guzman and agreed to meet in the parking lot of the convenience store prior to the shooting.
As of Thursday, Montgomery has not been charged in connection with Guzman’s murder, which remains unsolved.
Anni Guzman, one of Darlin’s sisters, told DailyMail.com she feels that after nearly 14 years of unanswered questions, the time has come to get justice for her brother.
‘Our family is in shock and processing the news as best as we can,’ she said of the latest development in the case. ‘At this time we are praying for the child involved which is what caused the arrest…although [Montgomery] is the person of interest in my brother’s case, this monster’s child is missing and that is something that the news should be really focusing on. Finding her.
‘My brother is gone and we know this but the whereabouts of the child still remain unknown and that should be the priority.’
Meanwhile, the search for Harmony Montgomery continues.
On Tuesday, New Hampshire Gov. Chris Sununu slammed a Massachusetts judge for placing Harmony with her father and stepmother in 2018 before the state could complete a study of their home.
Sununu, in a letter to the chief justice of Massachusetts’ highest court, described Adam Montgomery as a ‘monstrous drug dealer.’ The 31-year-old’s criminal record goes back to least 2007. In Massachusetts, he was previously convicted of shooting someone in the head and a separate armed attack on two women, Sununu wrote.
Sununu asked why the Massachusetts courts went ahead and placed Harmony with him. The governor said that at the time the court ruled, New Hampshire’s child protection agency had asked Massachusetts for additional information to complete the home study and would have likely found the father unfit.
‘It is unclear why the Massachusetts courts moved so quickly with this permanent placement prior to the completion of the home study. Why would the Massachusetts court choose to place custody of Harmony with this horrible individual? What caused such a fateful decision?’ Sununu demanded.
Sununu is requesting the court review the decision and all events leading to the judge’s ruling.
‘No child should ever leave Massachusetts in the custody of a dangerous criminal like Adam Montgomery,’ Sununu wrote. ‘We must ensure that, moving forward, at-risk children of our states are protected and adequately monitored.’
Harmony was 5 years old and living with her father when she was last seen in November 2019. She is pictured with her birth mother, Crystal Sorey
Massachusetts Court System Spokesperson Jennifer Donahue said that the Massachusetts Office of the Child Advocate has opened an investigation ‘into this tragic situation.’ The Massachusetts Trial Court, she added, was cooperating fully with that investigation.
Harmony Montgomery was last seen at a Manchester home in October 2019, when she was 5 and living with her father and his wife, Kayla Montgomery, who is not the girl’s mother.
Police in Manchester, New Hampshire, first learned Harmony might be missing when they received a call from Crystal Sorey, Harmony’s birth mother, in November, telling them that she had been trying to locate her daughter for many months.
Sorey had lost custody of Harmony in 2018 because of her substance abuse problem. She said she last saw her daughter looking ‘frightened’ on a FaceTime call around Easter 2019.
Police launched their missing person investigation in December 27, 2021, after an official with the Department of Children, Youth and Families reached out to the agency, saying Harmony could not bee found.
Since then, police have searched the house where the child was last seen.
Adam Montgomery was arrested earlier this month on a second-degree assault for allegedly punching Harmony in the face and giving her a black eye in July 2019, based on his uncle’s account.
He also faces charges of interfering with custody and child endangerment for ‘purposely violating a duty of care, protection or support’ by failing to know where the girl has been since late 2019 — the last reported sighting.
Prosecutors dropped a welfare fraud charge last week against Harmony’s stepmother, Kayla Montgomery, for collecting food stamps in the child’s name. The charge was replaced with three other charges, including theft.

Kayla was charged on suspicion of obtaining $1,500 in food stamps from December 2019 to June 2021 for Harmony, even though the girl was not living with the couple. She pleaded not guilty.
In an interview with police on New Year’s Eve, Kayla – who shares three children with her husband, ages 4, 2 and 1 – said she last saw Harmony in November or December 2019.
She said her husband was driving Harmony to the child’s mother in Massachusetts. She said she believed Harmony had been returned to the mother and never saw or heard about Harmony after that day, according to police records.
Kayla also told police she hadn’t seen Adam since October and had not spoken to him since November.
Police have received hundreds of the tips in the case and the reward fund has grown to more than $137,000.
