Why Did Adam Montgomery’s Murder Conviction Survive Less Than Two Years?

A jury in Manchester convicted Adam Montgomery of second-degree murder in February 2024. The New Hampshire Supreme Court erased that conviction before it reached its second anniversary. For families and followers who have tracked the Harmony Montgomery case from the beginning, the reversal feels like the system breaking its promise.

The ruling is procedural — the court found that trying the murder charge alongside a separate assault charge in one trial prejudiced the jury. The assault evidence was airtight: multiple independent witnesses, documented bruises. The murder evidence rested on Kayla Montgomery’s testimony alone — a witness who went to prison for lying before cutting a deal. The court said the strong case propped up the weak one, and the conviction couldn’t hold.

Criminal defense attorney Bob Motta (Defense Diaries) joins Tony Brueski to trace how the conviction unraveled so quickly. The joinder decision that created the structural vulnerability. The irony that the defense originally asked for the very setup they later appealed. Whether the trial judge had any way to see this coming. And what the unanimity of the ruling — all five justices — says about how obvious the error was once it reached the Supreme Court. Montgomery remains in prison on remaining charges. Harmony still has no grave. Tony Brueski and Bob Motta.
