"Due to the seriousness of injuries and the complexity of the scene, the NH State Fire Marshal's Office was consulted and responded to assist Derry Fire Investigators with determining the cause and origin of the fire," said Battalion Chief Ryan Bump.
It took firefighters almost an hour to knock down the fire, according to Bump.
The cause of the fire remains under investigation.
