A 19-year-old faces arson charges in connection to a southern New Jersey wildfire that has scorched at least 15,000 acres and prompted thousands of evacuations, officials said.

Authorities arrested the 19-year-old from Waretown, New Jersey, and charged him with arson and aggravated arson in the fire that’s still burning in southern New Jersey that they described as started with “an improperly extinguished bonfire.”
