BOISE - A grass fire along Idaho Highway 16 was started by a group of people, who were shooting at targets with a semi-automatic rifle Sunday, a Bureau of Land Management spokesperson said.
The fire, which eventually burned about 20 acres, was first reported around noon. It took crews about two hours to knock the flames down.
BLM spokesman Kevin Moriarty said two adults and a juvenile, shooting an AK-47 rifle, sparked the fire when a bullet ricocheted off a rock.
"It's really dry right now so shooting targets is a really easy way to start fires," said Moriarty. "People just really need to be aware of that and they could possibly get charged for the resources on scene."
Firefighters from Star, Eagle, Middleton, Meridian, and the Boise District BLM worked together to put the fire out.
