Shreveport police have released this video of a man peering into a jewelry store window just minutes before the place was burglarized.  He's later seen breaking into the store in the 4800 block of Line Avenue and making off with the goods.  The thief evidently was injured during the break-in...and blood evidence has been recovered from the scene.  If you can help in the meantime, call Shreveport detectives or Crime Stoppers (673-7373).
