A man was found dead Saturday morning in a burning house in Waterloo, Neb.
Travis Harlow, chief of the Waterloo Volunteer Fire Department, said the man had not yet been identified.
Authorities also had not determined the cause of death or cause of the fire at 303 Jefferson St.
Harlow said the Nebraska State Fire Marshal's Office is investigating.
He said the fire, which bgan about 7:30 a.m., produced black smoke rolling out of the windows and eaves of the ranch-style house. The fire had burned a hole through the floor of the house.
Firefighters contained it within about 10 minutes of their arrival, he said.
The body of the man, who was alone in the residence, was found in the living room. Harlow said an autopsy would be done in an attempt to determine the cause of death.
House fires are rare in Waterloo, he said, but his department also fought one late Friday night at 24235 King Lake Road. The Omaha and Valley Fire Departments assisted his department with both fires, he said.
The King Lake Road fire was contained to an enclosed back porch, Harlow said, but the eight family members were displaced from the home because of the smoke.
