Anytime I hear of a break in where property is stolen, the police are called, they make a report, you then send that off to your insurance company as part of a homeowners claim. You then get a check, minus your deductible amount. So if this situation has played out to the point of Mr. Frost getting arrested, then Mr. Grassley should be at this point, two cues and roughly $10,000 richer. If that's the case, then he's commiting insurance fraud here.
