We have no idea what’s going on. Here’s typically contradictory information:

Virginia Tech’s Web site earlier said one shooter was in custody and officials searched for a second shooter as “part of routine police procedure,” but during the press conference Monday, police said they believe there was only one shooter.

Police also said there is no evidence that the two shootings at opposite ends of campus were related.

Which is it?

One killer or two?

If these two shootings are unrelated, doesn’t that mean one of the killers is still on the loose?
