A trespasser was observed on surveillance video shortly before a massive blaze broke out at an RV dealership in Santa Fe Springs.
Police discovered the fire when they responded to a possible burglary about 12:30 a.m.
The 14 RVs destroyed were worth at least $150,000 each, KTLA reported.
The flames from Mike Thompson’s RV Superstore on Firestone Boulevard were visible for several miles.
The investigation is continuing.
