SUV arsonist charged

A Caltech grad student in physics has been arrested and charged with last summer's arson rampage against Hummers and other SUVs at four dealerships in the San Gabriel Valley. A month after the attacks, an emailer using the alias Tony Marsden messaged the L.A. Times claiming responsibility and affiliation with the Earth Liberation Front. The charged suspect, William Jensen Cottrell, 23, denies he's the one.
