I would have said the co-manager should be the new manager. Ideally the manager should have decided on someone who he thought was responsible enough for the job, so problems like this wouldnt occur, and the chances are he´d pick the co-manager. Or if not, there cant be much objections, as its managers choice.

So I dont really know if thats makes much difference, if the co-manager would return, or the manager would pick someone, but thats the way I would do it as I know the co-manager slightly and considering he is the highest position, and hes been there long enough, and I consider him a good enough manager, he´d be suited for the job.
