Thanks! Are they releasing any descriptions of the possible arsonist or arsonists?

For the Old Waterman fire: grey van, two Caucasian males. One of them apparently threw something out of the van, and then the van took off.

For the Rancho California fire: blue van (possibly with black top? conflicting reports), three males inside. No other information given. Seen departing the origin of the fire as the fire began.
