A homeless man is dead after catching on fire behind a business in Santa Rosa. The fire, which police believe was an accident, was reported early Saturday morning. Investigators say the man may have been doing meth or fentanyl then fell into a relaxed state and passed out. While he was out, the flame from his lighter came into contact with a flammable gel on the man’s hands or clothing. Police believe the gel was chafing fuel, which is usually used to heat food.
