MANCHESTER, N.H. (MyFoxBoston.com) -- Investigators say an explosion at a home in Manchester and the deaths of two people found inside were suspicious in nature.
Neighbors identify the homeowners as Bob and Connie Dion. They told FOX 25 the couple lived in the home along with their son and a teenage child.
Manchester police asked for the public's help in finding the couple's son, 38-year-old Matthew Dion. He is believed to be driving a white 2009 Nissan Altima with New Hampshire registration 3410587.
Investigators told FOX 25's Crystal Haynes the teen that lived in the home has been accounted for, but Matthew Dion has not.
Neighbors on Mooresville Road, where the explosion happened, called 911 Monday afternoon after they saw smoke billowing from the home.
The home is still in tact, though the front sustained damage and back of the ranch-style building was completely singed.
Officials continued to investigate the cause of the blast Tuesday. They believe this was arson, but do not know what specifically caused the explosion.
An unidentified man and woman were found inside the home. The Office of the Chief Medical Examiner is working to determine their identities, as well as the cause and manner of death.
