Harmony Montgomery Search Continues Before Father's New Trial

The Murder Case Is Starting Again, but the Search Never Ended

Harmony Montgomery’s father is scheduled to face a new murder trial after his earlier conviction was overturned, while prosecutors say investigators are still searching for the little girl’s remains.

Adam Montgomery was convicted in 2024 of second-degree murder in the death of his 5-year-old daughter. The New Hampshire Supreme Court overturned that murder conviction in June 2026, ruling that the way the murder and assault allegations were tried together jeopardized his right to a fair trial.

His other convictions, including falsifying physical evidence, witness tampering and abuse of a corpse, remain in place. He has maintained his innocence in Harmony’s death.

Why the Murder Conviction Was Overturned

The state’s case had included evidence tied to both a prior assault on Harmony and the later murder allegation. The New Hampshire Supreme Court concluded that combining those allegations created an unfair risk that jurors would use stronger evidence from one episode to decide the other.

The ruling did not acquit Montgomery of the murder charge. It sent that charge back for a new trial.

The state attorney general’s office sought reconsideration, but that request was denied. NBC10 Boston reported that the retrial has now been scheduled for Oct. 27, 2027.

That leaves prosecutors preparing to try the case again years after Harmony disappeared and without the physical evidence families often hope will bring certainty.

Investigators Say They Are Still Looking for Harmony

Harmony was not reported missing until 2021, nearly two years after investigators believe she died. Her remains have never been recovered.

Boston 25 News reported that prosecutors conducted another search as recently as last month. Senior Assistant Attorney General Ben Agati told the court that the search produced no recovery but said investigators have not stopped looking.

Authorities have previously focused on a roughly 26-mile route tied to a rental truck Montgomery used in Massachusetts. The exact location of Harmony’s remains remains unknown.

For the people who have followed the case, that unresolved search separates Harmony’s story from the court proceedings. A conviction was reached, overturned and is now headed toward another jury, but the question of where she is has never been answered.

The New Trial Will Revisit Evidence From the First Case

Lawyers told the court they will need to review thousands of pages of material before the retrial. They also must determine how the Supreme Court ruling changes what evidence can be presented and how the case will be structured.

Montgomery did not attend the recent scheduling conference. His attorney declined to comment afterward, according to Boston 25.

The new trial will again ask jurors to determine whether prosecutors have proved the murder charge beyond a reasonable doubt. His surviving convictions remain separate from that question.

The Family Still Does Not Have Harmony Back

The legal reversal means another trial, another round of evidence and another long wait before there is a new verdict.

For Harmony’s family, there is a second wait that has lasted even longer. Investigators continue searching for her remains while prosecutors prepare to take the murder case back to court.

The Case Has Already Passed Through One Full Trial

Montgomery’s first murder trial ended with a guilty verdict and a sentence that included decades in prison. The Supreme Court ruling did not erase the other convictions returned in the same case, which is why he remains incarcerated while the murder charge is prepared for another jury.

The retrial will not simply repeat every part of the first proceeding. Lawyers must work within the Supreme Court’s ruling and decide how to present the murder allegation without creating the same evidentiary problem identified on appeal.

That legal reset makes the case unusual: prosecutors already persuaded one jury, but they must now prove the murder charge again under a narrower framework while the search for Harmony continues outside the courtroom.
