Fort St. John, B.C.- The investigation into the cause of Sunday night’s blaze at  Rosenau Transport and Unified Valve is under way.

Investigators for the RCMP, Insurance Adjustors, and Fire department were in the building today to try to find the cause of the fire that levelled the building. They were not able to access the building until today because of hot spots in the debris.

The blaze Sunday night lead to the evacuation of the Peace Country mobile home park as containers of flammables exploded and sent thick clouds of smoke into the night sky. At least one mobile home sustained heat damage.

The damage estimate is not yet available.
