MANCHESTER, N.H. (Court TV) — A New Hampshire jury has found Adam Montgomery guilty of all charges in the death of his 5-year-old daughter, Harmony Montgomery.
After two days of deliberations, Adam was convicted of second-degree murder, second-degree assault, falsifying physical evidence, abuse of a corpse and witness tampering. Sentencing is scheduled for May 9.

Using a timeline put together by investigators, prosecutors argued Harmony was murdered in Dec. 2019, though she wasn’t reported missing for nearly two years. Her mother, Crystal Sorey, alerted police to Harmony’s disappearance on Nov. 18, 2021, after she was unable to reach her for months.
Editor’s note: The following story contains graphic descriptions.
Prosecutors said that Adam beat Harmony to death on Dec. 7, 2019, while the two were living in a car with Adam’s wife, Kayla, and the couple’s other children. Kayla told police that Adam was angry because Harmony would frequently have accidents in the car and that he would frequently hit her in the head with a closed fist.

Investigators said that over the next several months, Adam and Kayla moved Harmony’s body from the car, to banks of snow, to a cooler, to a ceiling vent and a walk-in freezer as they continued to conceal her death. Adam also tried to help decomposition with lime.
Investigators said that in the spring of 2020, Adam rented a U-Haul and took the bag with Harmony’s remains to dispose of them. Her body was never found.
Adam denied any involvement in his daughter’s murder but has not offered to help the police search for her. When police made contact with him on Dec. 31, 2021, they handed him a court order demanding him to cooperate and assist in finding Harmony, to which he responded, “either arrest me or I’m leaving,” and refused to answer questions.
Ahead of trial, a judge ruled that the jury would get to see his conversations with police where he refuses to help them find Harmony, and denied a defense request to keep out evidence related to the purchase of lime at Home Depot.
In their opening statement, Adam’s public defender admitted his client helped cover up Harmony’s death, but pointed the finger at Kayla for murder. Following the state’s case, the defense declined to put on a case.
Montgomery is currently serving a decades-long prison sentence in a weapons theft case. Although he waived his right to appear during his murder trial, prosecutors said they intend to file a motion requiring he attend the sentencing.
