Thanks for the added details, gruesome as they are. Maybe this will put to rest the absurd notion among many on this forum that the killing happened in a crowded restaurant and that everybody just sat around and let this guy hack the girl’s head off unopposed.
It is the rumour mill created by the police dept and the news services that have fostered the image of “uncaring tech students”. Locals have no respect for the kids and look for opportunities to diss them at every chance.
