They sound like items that can be traded for drugs.You will probly never recover the items.The local police will tell you that,I know.We had band equipment stolen and never found a thing.It was a good night for the crooks cause they got 3 or 4 other places on the block even the cops place across from my buddies house.But what ya gonna do?It always happens when your not around it seems.Good luck to ya,maybe look into getting a dog or 2.
