Firefighters were called to another suspicious fire in the middle of the night in Twentynine Palms. County Fire Battalion Chief Mike McClintock said the 2:30 a.m. fire was burning a motorhome in the area of Valle Vista and El Portal Avenue in the Desert Heights area of Twentynine Palms. Firefighters from Twentynine Palms, Joshua Tree, and the Combat Center arrived to find the RV fully involved in flames. They had the fire knocked down in about 10 minutes, but the RV was burned to the frame. The cause of the fire is under investigation. This is the third fire in Twentynine Palms in the early morning hours in a week. Firefighters responded to two fires on Sunday—one at 12:51 a.m. in the area of Valle Vista and Barbara Lane, which burned two motor homes; and then an abandoned single-family home in the 1500 block of Bermuda Avenue at 2:22 a.m. All the fires are suspicious in nature.
