Campus police said in a statement that 19-year-old Alexander Song of Fulton, Md., has been identified as the person who posted on a website plans for a rampage that would "kill enough people to make it to national news." The message also warned people to "stay away from the mall." Police did not elaborate.
Song was taken to a hospital for a psychiatric evaluation after his arrest Sunday. Song, who was not armed when he was arrested, faces a misdemeanor charge of disturbing school activities.
A police spokesman says it's unclear if Song has an attorney.
The university website describes Song as a member of a campus research program for select honors students who explore how science and technology relates with society. The Gemstone Program lists Song as scheduled to graduate in 2014. Police
say the university administration has moved to immediately suspend Song and ban him from campus pending a review.
