Adam Montgomery has been convicted in the death of his 5-year-old daughter, Harmony.

Her body has never been recovered. It only took the jury six hours of deliberation spread over two days, to hand down the verdict. Police said that “on or about Dec. 7, 2019,” Montgomery repeatedly struck 5-year-old Harmony “in the head with a closed fist.”

New Hampshire police say the then 5-year-old vanished sometime between November 28 and December 10, 2019. Her disappearance was not reported for two years.

The family of Harmony Montgomery says the New Hampshire Division For Children Youth and Families failed the little girl. According to Blair Miller, who adopted Harmony's younger brother, DCYF officials told him, Harmony had been reunited with her father. Miller had asked about the possibility of adopting Harmony as well.

According to court documents, Kevin Montgomery, Adam's Uncle, called DCYF after he noticed Harmony had a black eye. Kevin Montgomery later told police his nephew, Adam, admitted to physically abusing Harmony.
