Investigators said they haven’t yet figured out what caused the apparent leak of carbon monoxide from the propane gas heating system. New Hampshire Fire Marshal Sean Toomey said there were no carbon monoxide alarms found in the home, and he urged people to install and maintain such alarms. “This has been a terribly tragic year for both fire deaths and carbon monoxide deaths,” Toomey said. The CDC said more than 400 Americans die each year from unintentional carbon monoxide poisoning not linked to fires, while another 14,000 are hospitalized. When fire crews arrived, they found the home had elevated levels of carbon monoxide, Toomey said, adding that the deaths were believed to be accidental.
