Authorities are investigating two structure fires that occurred on the Fort Hall Reservation on Sunday. They’re asking anyone with information about either incident to contact the Fort Hall Fire and EMS Department at 208-478-3784 or the Fort Hall Police Department at 208-238-4000. The first fire started around 5:30 p.m. and involved a shed that was located behind a residence at 865 Sambo Road, according to a news release issued by Fort Hall Fire Chief Eric King through the Shoshone-Bannock Tribes’ Office of Public Affairs. No one was home at that time and no injuries were reported in the incident. But the flames did cause some damage, spreading to two other outbuildings and threatening another home to the north, King said in the news release. Firefighters from Blackfoot and American Falls assisted Fort Hall with fire suppression efforts and water supply during that incident.
