Delete a facebook account that has no admin?

[chickenwing]

So theres this problem but to cut to the chase I really need to know how to delete a facebook account that has no admin or creater. Is there a way to make myself admin and then delete it? Any help to get rid of the group would be appreciated.
and I do have to account of the person who created it and the password, the thing is it was a fake account that the group was made on, and then i deactivated the account. After i decided i wanted to delete the account i logged back on but now it says that there is no admin.
