The blaze was first reported at 4:25 a.m. on the grounds of the Dixon May Fair at 655 S. First St., Dixon Fire Chief Greg Lewis said. Firefighters arrived to find an older model, class A RV in flames.
According to Lewis, the two found dead hadn't been removed from the RV as of 5:45 a.m. The two injury victims - who were outside the RV - suffered second- to third-degree burns and were transported to a hospital.
Lewis said the burns the victims suffered indicate the blaze likely started near the front of the RV, but the official cause was under investigation. No other RVs or trailers were affected by the blaze.
