Can どれ mean plain what/who without selection?


In a comic book (犬夜叉) I found a plain

> どれ…

in a situation when a person sees that something bad happened. Somebody got
injured and the spectator apparently asks, who could have possibly done this.
I am just wondering why it’s どれ and not だれ or なに. It is a completely
unexpected event and there are no offenders to be picked from.

Is どれ used this way? The closest I could find was an example in a dictionary

> 「缶を開けて。」「どれで。」

But that didn’t satisfy me enough.

Another option is that I got the meaning completely wrong or that it’s not the
same „what“ どれ.
