What does wal-mart do with backpacks or bags they find stolen stuff in?

[TLow]

i was stealing at wal-mart at 12am and i had my backpack with the stuff i was stealing in it and i had to slide under the dressing room doors to put more stuff in and i heard an employee coming so i just walked out and left my backpack in there still open and when he left the dressing room desk my backpack was gone. What do they do with it and is there any way to get it back
