A suspected gunman fired shots inside a library at the University of Texas at Austin on Tuesday morning before shooting himself, university spokeswoman Rhonda Weldon told CNN.
The gunman died, Weldon said. No one else was hurt.
On its Facebook page, the university police said they were searching for a possible second suspect.
Weldon said it was not known whether that second suspect was armed.
Students and others on campus were advised to remain indoors with their doors locked.
