An arson investigation is unfolding in the North Bay. Three fires broke out last week in Petaluma. One burned a portable toilet near the soccer field at Lucchesi Park. Days later, flames damaged a parks department maintenance building. And that night, a third fire was reported near the Lynch Creek Trail, west of Highway 101. After that, officers arrested a man, Alexander Gasparyan, suspected of setting all the fires and say he was armed with a machete.
