There are unanswered questions surrounding an RV fire in the Cascades Conservation area. Fire Platoon Chief Larry Warner says that a 24 foot travel trailer somehow caught on fire Wednesday afternoon and he's uncertain about why it was there in the first place. He says it appears that the vehicle was abandoned at the site after being damaged in an accident and that the case is now in the hands of the city police. No one was inside the RV and there are no injuries to report as a result of the blaze.
