I couldn't find his reconstruction (did see the jacket photos though, thanks!) I may have missed this link in this thread previously but it does show photos of his belt, belt buckle, and phone as well:

The jacket isn't a true biker's jacket, it's sort of a lower end clothing item from the 90s even though it's made in Italy (the brand was marketed and sold here in the U.S. in department stores) so although he may have been a biker, he wasn't wearing riding clothes specifically. This passage leads me to believe he was homeless though, because these are the kinds of items someone with no fixed address would be likely to carry: (except for the phone which we've been debating)
"The sheriff's office said the deceased man was wearing Wrangler jeans 29x30, an alligator skin belt with a distinctive belt buckle, a medium Gianni Velente leather jacket and Timberland boots. He also was carrying a Motorola flip phone, lighters, Mennen Speed Stick deodorant, nail clippers and two small black combs."
