The tweet that led to the arrest of Kent State student William Koberna contained profanity, President Lester Lefton’s name, and threatened to “shoot up” the university, according to Eric Mansfield, the executive director of media relations for the university.

It was posted in public view on Wednesday, July 25; it was noticed by an unidentified Kent State employee Friday evening, at which time Kent State University police were notified.

The Kent State officers contacted Twitter to determine the owner of the account, then interviewed Koberna Saturday evening.

Charges were filed Sunday and Koberna was arrested without incident at his parents’ home in Brunswick that afternoon.
