A 20-year-old man died in New Hampshire after he was burned in an outside fire Saturday night that also injured a 17-year-old girl, according to the state fire marshal’s office. The man was identified by the state medical examiner’s office as Daniel Hewey of Warner. The two burn victims were found when authorities responded to Deer Meadow Road in Webster at about 10:20 p.m., according to a statement from the fire marshal’s office. Hewey was taken to Concord Hospital, where he died, the statement said. Investigators said Hewey used gasoline to ignite a brush pile, which caused a small explosion. “The cause of his death has been ruled accidental due to inhalation injuries and burns from the fire,” the statement said. The female victim was taken to Brigham and Women’s Hospital in Boston. She is expected to recover.
