Authorities are continuing to investigate what caused the fire that tore through a factory in Orange County.
Investigators say they are considering the possibility of a gas main break and cardboard boxes that were stacked near an infrared heater.
The fire happened Thursday on Midland and Wisner avenues.
It destroyed several buildings in the complex, which housed a movie studio and storage space rented by PepsiCo’s Frito-Lays and Amazon.
Officials say no one was hurt.
