This is horrific. (And, no, I'm not just talking about the tactless headline.) As soon as I notice any new news on who this guy was and why he decided to shoot over 20 people, I'll put it here.
EDIT: 3:45pm EST: The Star has updated their article. Estimates are now up to 31 or 32 dead, including the gunman. Still no indication of why he did it. Apparently, early in the morning they locked down the campus, after an initial round of shooting. Once the lockdown was lifted, at around 8am, another round ensued. So, at least some of the deaths are partially due to ineptitude. Nice.
EDIT: 6:20pm EST: Updated again. Estimates are up to 33 dead, including the gunman, and 26 wounded. Still no indication as to a motive.
