Justin Halstenberg, a 34-year-old man, has been arrested for allegedly starting the Line Fire in San Bernardino County, California, which has burned over 34,000 acres and forced evacuations around popular ski areas like Big Bear. Halstenberg faces multiple charges including arson of populated areas and possession of flammable materials, with bail set at $80,000. The fire has led to the evacuation of 4,500 residents and is threatening approximately 65,600 structures, prompting officials to urge residents to prioritize safety over property. Fire crews, facing challenging terrain and weather conditions, have only managed to contain 14% of the blaze, with at least three firefighters injured in the fight against the fire. This incident is part of a larger wildfire crisis affecting Southern California, which has seen nearly triple the acreage burned compared to the previous year. Authorities continue to investigate the fire's origins while expressing concern over the potential spread due to forecasted windy conditions.
