This seems to be pulled from the EPD blog, probably simply because of the cutesy news angle because the attacker is named Peace: https://www.eugene-or.gov/CivicAlerts.aspx?AID=2490.  Not that it excuses the attack, but it would be nice to know if this was a random attack or if the two knew each other, perhaps the victim incited him somehow. Camping on his usual spot? We don't even know if the victim was male or female.
