Apartment fire and explosions in Stockton, Calif.

Sources say propane tanks and paraffin were found at the scene of an explosion and a two-alarm apartment fire in Stockton that injured at least two people. While Stockton firefighters are investigating the exact cause of the blaze, sources say there were propane tanks and paraffin inside the rubble.
