Penfield, New York — An 8-year-old boy who saved the lives of six family members by warning them their trailer was on fire died after going back in to try to rescue his disabled uncle, said authorities in western New York state.

After the blaze on Monday, January 20,  firefighters found the body of Tyler Doohan, in the back bedroom of his grandfather’s mobile home in Penfield, New York, near Lake Ontario and about 300 miles northwest of New York City.

Tyler, along with his grandfather, Louis Beach, 57, and uncle, Steven Smith, 54, was unable to escape and died before firefighters could rescue them, Penfield Fire Chief Chris Ebmeyer said.

“There was fire rolling all over the length of the trailer and over their heads. They weren’t able to get outside,” Ebmeyer told reporters after the blaze. “Most likely the occupants were somewhat overcome with carbon monoxide poisoning and toxic gas released in fires.”

Neighbors called 911 upon seeing the flames, which destroyed the home outside of East Rochester.

The surviving six family members were taken to the hospital and treated for smoke inhalation and minor burns, Ebmeyer said.
