A professor was killed in his office at Delta State University in Mississippi, an official said Monday, and the campus remained on lockdown after reports of a shooter on the loose.
Bolivar County deputy Coroner Murray Roark said the dead man was in his mid-50s and was killed inside an office in Jobe Hall. He said officials are withholding his name for now.
University spokesperson Jennifer Farish said she was not yet able to identify the dead person, saying it was still an "active situation." It's unclear whether anyone else was wounded.
The lockdown began about 10:45 a.m. local time, with the university advising students, faculty and staff to take shelter and stay away from windows.
The university's Twitter account said the shooter was spotted near Jobe Hall.
State and local law enforcement agencies have responded.
The 3,500-student university is in Cleveland, in Mississippi's Delta region near the Arkansas-Mississippi state line.
