I encountered the following passage in a mystery manga. The detective character is explaining the evidence the "true" criminal (as opposed to the puppet killer described earlier in the book) left behind. The evidence had to do with computer data that the killer did not verify. I've done my best to reproduce it in the layout it originally appeared in
Could someone please explain the function of the bold と that doesn't seem to have a いう or equivalent after it and the bold が that doesn't seem to be functioning as a subject marker or a sentence connecting particle. Part of me suspects that the が is marking the subject of 与える and I would be satisfied with that explanation. I'm very uncertain about the と though.
