ATLANTA — Police say that an Emory student, arrested for threatening to carry out a mass shooting at Emory’s Oxford College, told the arresting officer she meant it as a joke.

Other Emory University students told 11Alive’s Blayne Alexander the threat was posted to Yik Yak, an anonymous messaging service. Students screen-captured the threat – later attributed to Emily Hikari Sakamoto – and called 911.  The message said, “I’m shooting up the school. Tomorrow. Stay in your rooms.
