GILLETTE, Wyo. (AP) - A teenage boy accidentally set himself on fire early Wednesday morning after allegedly trying to siphon gas from a firefighter's car. Police first learned of the injury after a 17-year-old boy and a 16-year-old boy claimed that someone had thrown gasoline on the 17-year-old at the Common Cents service station and lit him on fire, said Lt. Rod Hauge. The boy was taken to the hospital with second- and third-degree burns on his legs. Police were called to the hospital to investigate the incident and later learned that the 17-year-old spilled gas on his pants while siphoning gas. He then used a lighter to try to determine how wet his pants were and set himself of fire, Hague said. Both boys have been ticketed with larceny, Hauge said.
