Really, I have never heard of anything like that and I work in Blacksburg. My thoughts was something from high school, several of the victims and the shooter went to Centreville High in NOVA.
Cho’s sister worked for the State Department. There was a message in his rambling rant for her too. If you work in Blacksburg and never heard this, it doesn’t really surprise me. The investigation did literally everything in its power, (including releasing info by drips over a long period of time,) to keep people from realizong this was a terrorist attack.
It was a blatant coverup.
