BOISE (AP) — A federal judge has sentenced a former volunteer firefighter from southwestern Idaho to six years in prison for intentionally setting wildfires on public land in the summer of 2007.

Clyde Holmes Jr., 23, of Parma, was sentenced in U.S. District Court in Boise Wednesday. He was convicted by a jury in January of six counts of arson for setting six separate fires that scorched about 1,200 acres of private and public land in Payette and Canyon counties.

U.S. District Judge B. Linn Winmill also ordered to serve three years of supervised release and pay more than $155,000 to cover firefighting costs and property damage.

During the four-day trial, prosecutors linked Holmes to the fires with physical evidence, eyewitness testimony and cell phone records. Investigators say Holmes reported two of the fires moments after starting them.
