The incident was reported at about 1:20am local time, the school said in a Facebook post.
"We can confirm that there has been one fatality and one injured individual," the post said. "Both are believed to be students."
A lockdown was put on the campus 10 minutes later and remained in place for over three hours.
The gunman was described as a male, with the school calling on witnesses with any information to come forward.
Sunday's incident is the latest in a series of recent shootings on US campuses. On October 9, a gunman opened fire at Northern Arizona University, killing one and wounding three.
Services on campus to the general public are suspended today. Those who are not students, faculty or staff are asked to remain off campus.
