One day after a home explosion and fire left two dead in Manchester, their bodies have still not been identified and now police are hoping to speak with a man who lived in the house.

Police are calling the deaths suspicious and said they are conducting a criminal investigation.

Matthew Dion lived in the house with his two elderly parents but police said they haven’t been able to get in contact with him.

They said they are seeking 38-year-old Dion as a person of interest, he may be driving a 2009 white Nissan Altima with New Hampshire license plates 341-0587.

A next door neighbor said Dion’s parents, who owned the home, were very nice people but the son could be difficult.

“I know they had their differences that’s about all I can tell you. I didn’t know much about their home life,” Tim McGuire said.

Several unidentified family members described this as a very sad in difficult time. They said they spoke with the medical examiner but no one has been identified.

“It’s up to the investigators to determine what’s going on. I really have no clue, it doesn’t make any sense,” Pete Samon, a neighbor, said.

Police spent Tuesday sifting through the ashes in the home and at one point investigators focused on a shed behind the house.
