Long lost shotgun

I got a stranage call today, from the OKC police department. Apparently they found the shotgun of mine that was stolen during the burglary of my house in November 2004. He says they've had it since May, but this is the first I've heard of it. So I'm to pick it up sometime this week, though I must admit I'm a little torn about it. What if the thing was used in another crime?
