There wouldn't be much left to identify. That was the idea of using the press rather than just shooting him or something.

Often in such gory murders where the person is unrecognizable save for like the scar on the leg, itss very obvious that he was killed by the press.

Depending on the story she would have given them, admit or not admit to the crime what they might have done was analyze a blood sample to see if maybe a narcotic that may have rendered him helpless and befuddled and allowed her to easily manipulate him to come to the factory and the press and then maybe knock him out in a way that he would fall on the press as he would have been pretty heavy for her to prop up on her own.

The press was set to zero for the purposes of crushing an object to non existence although in reality no press could do that.

Actually, a far bigger plot hole is that in exchanging heads with a fly, the scientist would have traded a brain with about 86 billion neurons, for one with only about 135,000. The scientist's head was gone, replaced with a fly head, equipped with a fly brain. He would not have been capable of any of the things we see him do in the movie, like trying to conceal from his wife what had happened to him, burning his notes, and killing himself in despair when he realizes there's no hope of reversing what's happened to him. Even assuming the clumsily produced hybrid organism could have survived for more than a few seconds (unlikely), he simply wouldn't have had the human-level intelligence he continued to display after the incident.
