One week ago today, the unthinkable happened. A deeply troubled young man, armed with an array of weaponry, broke into an elementary school in Newtown, Conn.
He started shooting and didn't stop until he had killed 20 of the school's young students and six adults. Adam Lanza had murdered his mother in her bed before arriving at the school.
His final act of violence was turning the gun on himself as police and emergency workers converged.
We join millions of others across this great nation in asking, "Why?"
In the days since the killing, investigators have dug into Lanza's life and found a loner who was, as one official described, self absorbed.
He reportedly lived with his mother and largely kept to himself. There were no clear indications that he was capable of the murderous rampage that ultimately he went on.
Friends, associates and former teachers gave much the same report on Lanza:?while he was something of an odd individual, no one thought him remotely capable of mass murder.
But he was, and that's at least a part of the problem. It isn't against the law to be, and act, unusual in this or most countries.
Researchers in previous mass killings typically uncover behavior in the days and weeks leading up the killings that could have given hints that disaster was just around the corner. We suspect that's how it'll be in this tragic circumstance.
But today, the focus will be on the victims and their families and friends. And the question remains, "Why?"
