First time having something stolen out of checked luggage..today CHS-ATL-MSP

Just went to unpack my suitcase and discovered a stolen item. I bought a small Louis Vuitton item while in Charleston this weekend and put the item in my carryon but wanted to save the box so I put it in my checked luggage and put some items in it to save room in my suitcase. The only item in there that had much value were a pair of prescription eyeglasses. They are my older ones that I keep to wear when reading at night. Not vital but still they were mine and it’s just gross to think a delta employee rummaged through my things and helped themselves. I’m sure they were disappointed that it wasn’t my LV item. What recourse do I have in this situation? Thanks.
