Investigators are trying to figure out what led to an inferno which gutted a huge warehouse in Oxnard and forced the closure of some nearby schools.
The fire was reported just before 10:30 Tuesday night on the 200 block of East Colonia Road.
Oxnard firefighters arrived to find flames shooting through the roof of the building, which was a former Sunkist packaging plant. They were able to keep the blaze from spreading, but it took hours to contain it.
The fire led to shelter in place orders for some nearby residents. It shut down Oxnard Boulevard and disrupted train traffic thorough the area. The building was believed to be unoccupied at the time. No injuries were reported.
As a precaution, the Oxnard School District closed Ramona, Chavez Rose Avenue, Brekke and Frank Schools.
