The father of missing New Hampshire child Harmony Montgomery is a suspect in a 2008 Massachusetts murder investigation, according to reports.

Adam Montgomery is currently in custody in Manchester, New Hampshire on child abuse charges as 7-year-old Harmony remains missing having not been seen since 2019.

The murder investigation yet again calls into question how child protective services allowed Harmony to be placed in Montgomery’s custody prior to her disappearance.

Guzman was pronounced dead in hospital after being riddled with bullets outside a convenience store at around 11 pm.

The store’s owner witnessed Guzman fighting with another man shortly before the incident. The suspect white male in his mid-20s, about 6 feet tall and of a thin build.

At the time of the incident, Montgomery would have been 18 years old. He has not been charged or publicly identified by the police.

This crime was revealed in a scathing letter written by New Hampshire Gov. Chris Sununu in which he harshly criticized a Massachusetts court for leaving Harmony with her father without a thorough investigation.

While Harmony’s mother was still expecting the now-missing child, Montgomery was accused of shooting a man in the face after crossing state lines to buy drugs.

He took a plea deal and served prison time.
