South Bend, Ind. A South Bend man was found dead Saturday morning after his house started on fire.
Now, new details have led authorities to believe the man, 51-year-old Jason Losso, intentionally started the fire before shooting himself in the head.
Police responded around 6:15 a.m. Crews were sent to a home in the 5500 block of South Miami, south of Erskine Plaza.
Firefighters arrived to find flames shooting through the roof, making it difficult for them to enter the home safely. When they finally entered, Losso was found dead inside.
The structure's dangerous conditions limited the amount of time firefighters were initially able to spend inside.
"There were flames through the roof of the house," said South Bend Fire Chief Steve Cox. "Our initial tech crews had difficulty making entry just because the amount of heat the amount of flames involved."
The roof of the home ended up caving, making the search even more difficult.
"So that creates a certain amount of danger for our firefighters right now," Cox said. "They haven't been able to conduct a secondary part of the search. At this point in time we're trying to come up with a strategy to be able to do that."
Neighbors say Losso lived alone and kept mostly to himself.
"The house always looked like it was deserted," Neighbor Karen Guerrero told NewsCenter16. "Nobody was there. He always had foil and other things up in the windows and it was pretty closed off."
Some say it was apparent that the man did not have running water and other utilities. Neighbors had sent authorities out to check up on him in the past.
Guerrero said she'll remember Losso for his act of charity in the winter -- shoveling the sidewalk for the entire block.
"He was a kind heart," she said. "I mean my husband and I both work so for someone to shovel our snow in the middle of the night is awesome to me. He had a big heart and he meant well."
The fire marshal has determined that Losso set his home on fire, but investigators are still working to determine what accelerant he may have used.
