Oh yeah he probably had a load of stuff he didn’t like, but there’s a lot of stuff he could’ve done with the extras- donate it, sell it, gift it to friends.
There’s been more than 1 serial killer, for example, who gave their wives, girlfriends or female friends items of jewellery they’d stolen from the bodies of victims. It gave them a thrill to see their families unknowingly wearing items belonging to the women they’d killed. I’m of course not saying that Brinton is a serial killer but it’s possible that he’d get a similar kick out of seeing other people wear the clothes or jewellery he’d stolen as he had from wearing it and being photographed.
