I know the Wrath T-shirt and Dylans trench and I believe hat were given back to his family.
I don't know what happened to his ring, earring and necklace. I assume that went back to to them too. I venture a guess and say the Wrath shirt was probably burned or discarded... the ring and necklace are one thing and even his beloved hat but I doubt they'd want to keep that shirt. Just my opinion.
