Not new evidence. Not proof of innocence. A procedural flaw — one his own defense team originally helped create — brought the entire murder conviction down. The New Hampshire Supreme Court ruled unanimously that trying Adam Montgomery’s December 2019 killing alongside a separate July 2019 assault in a single trial was unfair. Five justices said the trial judge should have separated the charges. That decision cannot be undone. The July assault evidence was overwhelming: multiple witnesses, documented injuries, no dispute. The December evidence — the night five-year-old Harmony died — rested on one witness. Kayla Montgomery. Adam’s estranged wife. A woman who went to prison for lying to investigators before she agreed to testify for the prosecution. The court found the strong July evidence bled into the weaker December case and tipped the scales. The defense theory — that Kayla was responsible and Adam only covered it up — never got a fair fight. Criminal defense attorney Bob Motta breaks apart the legal mechanics of this reversal: what “prejudicial” actually means in practice, why the defense ended up arguing both sides of the joinder issue, whether the trial judge should have caught this, and what people fundamentally misunderstand when they hear “conviction overturned.” Montgomery still faces decades behind bars on the charges that stand — second-degree assault, falsifying evidence, witness tampering, and desecrating Harmony’s remains — plus a separate thirty-two-and-a-half-year firearms sentence. He is not getting out. But the murder conviction was supposed to be the one that said what happened to this little girl and who did it. That conviction is gone. Prosecutors have vowed to retry. And Harmony has never been found. Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/ Want to comment and watch this podcast as a video?
