Where can a defendant be reported to who knowingly lied about their assets when being sued for a dog bite

A gentleman filed suit against an owner of a Rottweiler for injuries he sustained by being bit by the dog. The defendant owns a home but was over a year on arrears on payments therefore the homeowners policy was lapsed. The plaintiff won his case but the defendant claimed he had no size able assets. When he did this he had a pending lawsuit against an insurance company for being injured while attending a fire because he was a local volunteer firefighter . He did not disclose this pending lawsuit. Now the case he had settled and he received a size able amount of money. He's now bragging about getting this settlement and is goin hog wild with buying all sorts of things. Trip to Mexico, a brand New Harley Davidson motorcycle, etc. If someone knew he falsified his info at the time he was sued who can they report this person to for purgery? In the meantime he's blowing all this money while the plaintiff has permanganate scars and damage from the defendant' negligence.
