Insta user, @escty, 40,000 followers. Apparently also a popular 4chan user who went by the handle Oxychan, so one of us maybe?
Killer posted pics of her slashed open throat to his insta (which have since been removed, obviously). Tried to suicide by slashing his own throat as well, but failed and was eventually talked out by police.
Girl was only 17. Tragic really, but murdering an insta thot and posting pics of her mangled corpse to insta is technically the most ultimate form of thot patrol someone could muster. The only way you could top what this guy did would be to post the pics to her insta instead of your own.
