The building, which sat just off Kings Highway, used to be an experiment station for the OSU Extension Service, but had been abandoned for a few years. Medford Fire said the fire was human-caused, and they are asking anyone with information to come forward.
Firefighters said they were told kids would sometimes hang out around the building, but they have not named a suspect.
“This was certainly an area where kids cruise by,” said fire investigator Samantha Metheny. “It’s an abandoned building, and it’s a place of curiosity.
Firefighters were able to stop the fire quickly Tuesday and prevented it from spreading too far into a field of dry grass. Firefighters said OSU Extension employees had planned to cut the grass, but were not able to do the work before the fire broke out.
