Difficulty understanding the following sentence 穴？ 一体何を証拠に…


So usually when there is an omitted part of a sentence its pretty
straightforward to know what the rest of the sentence way going to say.
However in this case its really confusing me.

This is a scene from an anime where the person speaking is being accused of
digging holes on a race track to prevent the other person from winning:

穴？ 一体何を証拠に…

Not only am I unsure of what the renaming part of the sentence could be, but
the を particle is also throwing me off, something keeps irking me that it
should be が.

I did some googling and 何が証拠になるのか seems to be a commonly reoccurring phrase,
but nothing comes up with を.

Any help or clarification is much appreciated.




This 何を証拠に is a `AをBに` ("with A as B", "using A as B") construction, which
forms an adverbial phrase.

  * [Two を in a single sentence - how to understand it?](https://japanese.stackexchange.com/q/16288/5010)

The literal translation is "With what as the evidence...?" or "Using what as
the evidence...?" Something like そんな事を言うんだ or 俺を犯人扱いするんだ is omitted after
this.

He could have said 何が証拠だ or 証拠は何だ instead, which is a complete sentence on its
own.
