The deadliest school attack in U.S. history took place this morning at Virginia Tech. At the time of this writing 22 are dead, but it sounds like that number will rise.
We don't yet know the name of the shooter, but I'm going to jump to the conclusion it's a male and he left digital clues as to his mindset. When Kimveer Gill opened fire on students at Montreal's Dawson College last September, he left clues all over his online Vampire Freaks page. I'm guessing we'll learn something similar about today's shooter.
In 2007, when a young person feels the hate and bitterness required to plan something of this nature, it always spills onto the web before blood is spilt in the hallways. There's likely a blog, bulletin board postings or some form of online discussion that will reveal his state of mind. We'll likely wonder why we missed the clues when he was digitally screaming for help.
This is all speculation at this point and I only know the scant details available at CNN.com, but I'm fairly certain he left cyber bread crumbs on his road to infamy.
