A team of fire investigators says the Two Bulls Fire and now a third fire that popped up on Tuesday are all suspicious and a reward has increased to $26,500.00. Both the County and City added $5,000.00 each to the reward fund. Capt. Shane Nelson with the Deschutes County says they consider all three fires not just human caused, but possibly arson. The tip line is 1-877-876-8477.
