A total of seven cars in San Francisco were set ablaze since Saturday. Early this morning, according to CBS 5/KCBS, "Arson investigators responded to the scene of two early morning car fires in San Francisco," one in the Outer Richmond and another in the Western Addition. Also, a pickup truck was torched at 29th and Geary, bringing this morning's total to three. While it's still too early to determine whether the injured autos, a minivan and Volvo station wagon, are related to the other four immolated autos that happened over the weekend, it sure does look suspicious. Cars were previously set on fire, starting on Saturday, at 3 a..m in the Financial District on the 200-block of California Street, between Battery and Front streets; Saturday night at Franklin and Fern streets; Sunday morning at Van Ness Avenue and Olive Street near the Civic Center; and Monday at around 2:30 a.m. on 12th Street near South Van Ness Avenue. No word yet if the Auto Arsonist and the Toilet Torcher, the pyro who torched porta-potties in early 2009, are the same person, but hopefully not. We don't care much for crossover arsonists. (Har.)
