Stevenson believes the blaze started in a common area on the first floor of the home.

“The house is completely gutted. There’s huge holes in the floor,” he said. “From what I can see being a fire chief for many, many years in this town as well, it looks like it started in the living room, that’s where they’re working. That first floor up to the second floor on the left side of the house is completely gutted.”

The Gloucester County Prosecutor’s Office and the fire marshal are teaming up for the investigation. The Red Cross is assisting the family with lodging.
