Local photographer Jesse Narducci sent us these shots taken Tuesday night outside the three-alarm fire at 1626 Palo Alto St.

Investigators are still at work trying to determine the cause of the blaze, which is estimated to have caused millions of dollars' worth of damage.

They are looking at the possiblity that the fire may have started behind the building on a patch of land near the 101 and spread to the building.
