Police officers in Bannockburn, Ill., have charged a black female student at Trinity International University with sending the threatening notes that led the institution to evacuate its minority students last week.

The student will be charged with disorderly conduct and a hate crime. Her name has not been released.

According to the police, the student confessed that she had sent the notes because she wanted to convince her parents that she should leave the university, which is located outside of Chicago. Law enforcement and Trinity International officials now believe that the university's minority students were never in danger.

The notes made specific threats of violence toward minority students and prompted the university to send all of its minority students to off-campus hotels. The evacuation attracted nationwide attention from the news media.

The president of Trinity International, Greg Waybright, has closed the campus to reporters, citing concerns about the impact of all of the publicity. But he issued a statement in which he called the arrest "an agonizing moment for Trinity," saying "we are heartbroken by this revelation because we consider each student a member of our family."
