(AP) - Students say his sacrifice saved lives.
E-mails to the widow of an Israeli engineering professor killed in Monday's shootings at Virginia Tech describe how Liviu Librescu blocked the doorway of his classroom with his body and asked students to flee. They started opening windows and jumping out.
Also among the victims was a 51-year-old engineering professor from India. His brother says their elderly parents have completely broken down. He says "it was like an electric shock. We've totally collapsed."
