Father sentenced to life in jail for killing his 5-year-old daughter Harmony Montgomery has murder conviction OVERTURNED in shocking reversal

By EMMA RICHTER, US SENIOR NEWS REPORTER Published: 17:51, 11 June 2026 | Updated: 17:58, 11 June 2026 The father of Harmony Montgomery has had his murder conviction overturned after he was sentenced to life behind bars for killing the precious five-year-old.  Adam Montgomery was granted the shocking ruling on Thursday morning after the New Hampshire Supreme Court determined that he was tried for too many convictions at the same time, WMUR reported.  Adam, 36, was found guilty of murdering Harmony in 2024 after the little girl disappeared in December 2019.  The new decision does not mean he will be freed from jail.  At the time of her disappearance, Adam repeatedly punched the innocent child in the face after she had a bathroom incident while sleeping in a car.  He and his wife, Kayla, Harmony's stepmother, then took opioids and ate fast food as Harmony died of her injuries in the backseat. Her body has never been found.  Adam was convicted of second-degree murder, abuse of a corpse, witness tampering, and falsifying physical evidence. But in October 2025, Adam's lawyer argued that his client should have been tried separately on the assault and murder charges.  Adam Montgomery was granted the shocking second chance on Thursday morning after the New Hampshire Supreme Court determined that he was tried for too many convictions at the same time Adam, 36, was found guilty of murdering Harmony in 2024 after the little girl disappeared in December 2019 The state argued that the joinder, or combining multiple criminal charges, was 'harmless,' but supreme court justices disagreed.  'We conclude that the misjoinder of offenses was not harmless as to the homicide charge. Accordingly, we reverse the defendant’s conviction of second-degree murder,' justices determined.  Adam's lawyer also argued that the court should not have allowed Kayla's testimony, and that police bodycam footage should not have been shown at the trial, according to the outlet.  Breaking news... updates to follow No comments have so far been submitted.
