"My whole heart ached for Walter, it really did," Michael's aunt Patricia Nolan said. "Michael's at peace right now because I don't think Michael had a happy life, although Betty and Walter tried to do everything for him."
She went on to say that Michael was very troubled and her family suggested he be institutionalized.
He was one of five children and lived at home for his entire life. His parents even took in his daughter for several years. His mother died a few years ago, leaving Walter and Michael alone in the house.
"I dont know how he lived these last couple of years without Betty there because I think she kept everything together," Patricia said.
Neither Michael or Walter had a record prior to this incident.A spokesperson for the New Hampshire attorney general indicated that it may have been fueled by propane, however an official cause of the fire and explosion has not been released.
