What do thieves do with art once they've stolen it? This is one of the key questions asked in this CNN interview with Chris Marinello from The Art Loss Register. Marinello states these are frequently crimes of opportunity and usually are not done with a specific buyer in mind.
Those who purchase stolen art are frequently unaware, whether willfully ignorant or innocently oblivious. This is why Marinello argues the importance of registering stolen artworks and suggests collectors check the database before purchasing works as well. Many artworks are not entered into the database, which is why as little as 1-5% of stolen art is ever recovered.
