Jeremy confirmed to be the bite victim?

I was looking at TFF sample book and saw something I found interesting.. on the 3rd page of the sample for TFF the 3rd thing we learned from phone guy was that "someone had a daytime run-in with a animatronic and lost his or her frontal lobe, but survived." The "Jeremy was the bite victim" is as old as fnaf 2 it's self. I've believed in it for a while but this seems (to me) to give a direct hint that it was Jeremy. We hear phone guy tell us on night 5 of fnaf 2 that they're closing down and we'll be working the dad-shift because they have one last event, a birthday. I could totally be looking to far into this but to me this is a little bit more of a hint that it was Jeremy. What are your thoughts?
