Gambrell Hall was closed Friday morning due to a death investigation by the State Law Enforcement Division and other agencies.
USC director of public relations Jeff Stensland called it an "isolated incident" and emphasized that there was "no danger" to students.
University President Harris Pastides released that the deceased was a doctoral student in an email sent to students Friday afternoon. Pastides called the incident "tragic," and encouraged students as well as faculty and staff to reach out to counseling services.
Gambrell Hall reopened Friday, but classes remained canceled in that building only. Classes are expected to resume Monday, according to Stensland.
Students can reach USC's counseling services at 803-777-5223. Faculty and staff can speak with the Employee Assistance Program at 800-633-3353. If you or someone you know is struggling, the National Suicide Prevention Hotline can also be reached at 1-800-273-8255.
