I suppose it depends if there was anyone to register it, perhaps one of our members who have an ancestry account might be able to have a look for you but I think a certain amount of time might need to pass before the info is available, might be worth a look though.
Just had a quick look on a US website (Wisconsin) and it seems you might need some identification to get a copy of a death cert and you probably won't have any of it. Other states I imagine will have their own rules.
Good luck.
