Investigators now believe a 5-year-old New Hampshire girl who disappeared in 2019 was murdered

 Investigators now believe a 5-year-old New Hampshire girl who disappeared in 2019 was murdered, authorities said Thursday. The long search for Harmony Montgomery, who was only reported missing last year, has become a homicide investigation, Attorney General John Formella said at a news conference Thursday. Authorities believe she was killed in Manchester in early December 2019. Her case has prompted a widespread outpouring of support around the state, including several vigils aimed at raising awareness of her case. Several Facebook groups also were created aimed at sharing news on her case. “At this point, while Harmony’s remains have not been located, we do have multiple sources of investigative information including just recently confirmed biological evidence that has led us to this difficult and tragic decision,” Formella said. Police first became aware that Harmony might be missing when they received a call from the girl’s mother, Crystal Sorey, in November. She had been unsuccessfully trying to locate the girl for months, police said. Police said they contacted Harmony’s father, Adam Montgomery, and other family members by the end of December. According to court documents, police told him that Harmony had not been seen in more than two years and there was concern over whether she was still alive. “Our commitment to bringing Harmony home has not wavered, nor will it,” Manchester Police Chief Allen Aldenberg said Thursday. He implored anyone with information to come forward.
