Firefighters were called to a small vegetation fire in Yucca Valley Friday evening. About 8:30 p.m., several passers-by reported a fire behind the Starbucks and McDonalds just off Sunnyslope near the intersection with Warren Vista. County Fire Battalion Chief Donnie Viloria said a 50-by-50- foot spot of vegetation caught fire due to an illegal cooking fire in a homeless encampment behind the businesses. One person sustained minor injuries and was treated by paramedics at the scene. Yucca Valley and Joshua Tree firefighters completed an aggressive attack and kept the fire from spreading to nearby structures. It was contained in under 10 minutes. No property was damaged in the fire.
