I think you better check shelters in the area in case someone dropped him at one.And I'd knock on doors in the area.Stay a few feet away when they open the door.To ease them and you.Daytime only.Check neighbors within a few blocks random in case they picked him up or knew their own neighbor has a NEW cat that looks like him.And I would call to see if a cat was found on the road hit and picked up that looked like him.Good Luck and prayers on the way.
