The morning's fire broke the house in rural India, killing six including four children, and the authorities had reason to believe that the fire was intentional, the report said.
The WTHR reported that an unnamed resource from Cass County, which was in place, increased the possibility. Indian State Police Sgt. Tony Slocum for The Associated Press said: "We will consider it a criminal investigation until we find out otherwise – it's all comprehensive."
Slocum told The Associated Press that the crews who helped dead dogs in late afternoon found two bodies beside the body of an adult man, an adult woman and two children who had previously appeared. Slocum said he did not know the age or sex of the last two found bodies.
The report states that the dead included a 42-year-old man and his ten-year-old daughter. The body of a 25-year-old woman also appeared on the scene with her three-month-old boy, 1-year-old girl and 3-year-old girl.
Neighbors reported fire on Friday, Wednesday, in a house north of Indianapolis. Two Cass County Sheriffs arrived in a few minutes and tried to enter the house, but they were fired and fired, said Sheriff Randy Pryor.
Two adults escaped the fire and were taken to a local hospital. Pryor said the two survivors spoke to the investigators.
The house was mostly flooded with flames when firefighters came in, which prevented rescue attempts, said Lt. New Waverly Fire Lt. Steve Crispen.
The roof of the building collapsed after a fire broke out most of the interior of a two-story house with wooden frames, Crispen said.
Air efforts were avoided by the lack of fire hydrants near the house. The fire crews ran out of the water and had to wait about five minutes before another tanker arrived, Crispen said.
"It is quite disturbing when the initial expedition tells us that people are captured in the structure and that they say more people," Crispen said. "It's one of the hardest days I've probably had in my life."
Three state fire investigators were in place to find out the cause of the fire, state fire marshal James Greeson said, adding that it would not be easy to move forward.
"We have a digging unit that will systematically pull us apart so we can enter and actually carry out our investigations," Greeson said.
