An eight-man, four-woman jury on Thursday found Justin Halstenberg guilty on nine of the 12 arson counts he was charged with relating to setting three fires in Highland on September 5, 2024, the last which took hold and burned up the foothills of the San Bernardino Mountains and across the San Bernardino National Forest, charring 44,780 acres in its northeasterly progression all the way to the outskirts of Big Bear in becoming the fourth largest fire in recorded county history.
