The as of yet unexplained fatal shooting of a newscaster and a cameraman in Virginia has led to a lockdown of schools in three counties, according to a tweet this morning:
Bedford, Botetourt and Roanoke County schools are all on partial lockdown (students not allowed outdoors).

The suspected gunman has yet to be apprehended by police.
It remains unclear how the isolated incident endangers thousands of school students.
