A fast-moving fire in New Hampshire claimed the life of a young boy early Wednesday morning.

Rescuers tried to get to the child, but the flames were too intense.

The state fire marshal’s office said three adults and four children were able to escape the burning home on Thorwald Avenue, but one young boy never made it out.

Firefighters believe the fire started sometime after midnight.

Hampton fire and police responded to several 911 calls at 12:40 a.m. They say when they arrived, the home was heavily involved with fire.

Hampton Fire Capt. Justin Cutting said firefighters made several attempts to try and rescue the child, who at the time was unaccounted for, but the fire was too intense and crews were unable to gain access inside the house.

Only after the fire was out, did they find the boy’s body inside.

“Due to the volume of fire and the wind conditions, it was rapidly extending to the exposures on all three sides. The companies began to attack the fire, protect the exposures, and conduct some primary searches of the building,” Cutting said. “The fire building was heavily involved. There was no access made to that initial building.”

The police chief said one woman was taken to a Boston hospital with burns and smoke inhalation.

The fire also spread to a neighboring home and firefighters evacuated several neighbors.

The cause of the fire is under investigation.
