At 64 years old, Richard Benson is positive that he has already lived through the worst day of his life.
It was April 16, 2007, and Benson was in Puerto Rico for a conference of university engineering deans. He started the day excited to spend some time away from his office at Virginia Tech University. Then at 9:27 a.m., he received an e-mail that jostled him out of his good mood: “A shooting incident occurred at West Ambler Johnston earlier this morning. Police are on the scene and are investigating.”
