So what about Oswalds keys to his boarding house front door, his close-able partition room, his P.O. Box, and what about his bracelet, ring, wallet with 13$ cash ( about $100 in 2021), and his fake ID. In the wallet.?
Either he must been doing his lifting moving and wrapping job with all these items in his loose pants with only T-shirt on, or he put some or all, in his brown shirt and or jacket pockets which shirt/jacket were left elsewhere either Domino room or some storage room.
