I am currently a college student in a small town (pop 40,000) and a college with a population of 5,000. It is not difficult to find out where a certain person lives through asking around my college. 

On my colleges garage sale facebook group I had commented on a post that Person A submitted and Person B, the comment right above me, had commented something to piss off Person A. Person B's comment really pissed off Person A. Person A privately messages me threatening violence against me, property damage, and wanting for us to meet up to fight; I ask him why the hostility and he references Person B's comment. He thinks that I posted the comment. I inform him in a neutral manner that he has the wrong person but that doesnt stop or slow the attacks against me, I am assuming he never checked to confirm the identity since he keeps on repeating how I posted and should delete the comment. Person A stopped messaging and threatening me after he realized that I would not reply to him. I am personally afraid that he will go good on his threat on me. Should I file a police report on this? Person A and I have never physically met each other and this was out very first interaction with each other (no clue he existed at my school).
