The New Hampshire Attorney General announced on Thursday that the Manchester home explosion is being treated as a homicide investigation.

A medical examiner completed autopsies on the bodies found at the scene and identified them as the two homeowners: Robert Dion, 71, and Constance Dion, 67. Officials have not said how the couple died.

Police are still looking for the 38-year-old son Matthew Dion, who lived in the home with his parents. He hasn’t been seen since the fire on Monday.

An investigation is ongoing.

Any member of the public with information concerning this incident is urged to call the Manchester Police Department at (603) 668-8711.
