The Associated Press reports that William Kordsmeier, a economics professor at the University of Central Arkansas, will be retiring after a classroom incident in which he threw a marker at an allegedly disuptive student:

According to a university police report, 20-year-old Cesar Francisco Orea said he was quietly taking notes in class when Kordsmeier threw a marker, similar to a highlighter, that struck him in the face and told him to leave. Kordsmeier told police that Orea was disrupting class and that he’d tried to start his lecture several times. Kordsmeier says he was trying to get Orea’s attention.
