US universities evacuated due to bomb scares

Campus bomb scares and perceived threats forced lock-downs and evacuations at universities in Texas, Oklahoma and Tennessee on Tuesday, a day after a Virginia Tech student's shooting rampage killed 33 people. In Austin, Texas, authorities evacuated buildings at St. Edward's University after a threatening note was found, a school official said. Police secured the perimeter around the campus and were searching the buildings, St. Edward's University spokeswoman Mischelle Amador said. She declined to say where the note was found and said its contents were "nonspecific."
