Coos County District Attorney Paul Frasier said two brothers - Christopher Thorp, 13, and Grayson Thorp, 8, both of Roseburg - died from apparent smoke inhalation.
The third boy - Caden Teddleton of Coquille - was taken to a burn unit at a Portland hospital, Frasier said. The boy was listed in critical condition with burns and smoke inhalation at last check, he said.
