The body of Southern Methodist University sophomore, Hannah Catherine Moss, was found Tuesday in her off-campus apartment in Dallas.
A cause of death hasn't been determined yet, but foul play is not suspected.
The 20-year-old Austin native was a member of the SMU track and field team and Chi Omega sorority.
"It was the absolute worst thing to find out that you've lost your best friend," said Courtney Madden.
Counselors will be available to help students, faculty and staff grieving her loss.
"She was a free spirit," Madden said. "When you think of Hannah, you just think of the girl who just did what she wanted to do."
Moss is survived by her parents and two siblings.
Her funeral is Monday, March 24, at Emmaus Catholic Church in Lakeway at 1 p.m.
