I am not sure what the correct answer is for this or what information I should give.

It is late August in Houston, Texas, and you are investigating a fire that occurred at a facility that stores motor oils and other lubricating oils.A witness points out a man who allegedly ran from the structure about the same time that the fire started.You question the man, who turns out to be the owner of the facility.He tells you that he was checking his inventory when barrels of waste motor oil stored in an unventilated back room spontaneously burst into flames.The owner claims that the fire spread so rapidly that he had to flee the building before he could call 911.After speaking with several employees, you learn that the building had no air conditioning and that the oil had been stored for almost a year in the cramped back room.You also learn from a detective assisting on the case that the owner increased his insurance coverage on the facility within the past three months.Should you believe the owner's story, or should you suspect arson?On what do you base your conclusion.A short answer here is okay.
