Texas State University police are searching for a student accused of making death threats.

The school's website warns that the student could be armed and near campus.

Nathaniel Joseph Doyle, 22, is accused of making comments about killing people. He recently sold his vehicle and bought a pistol, the Texas State University Police Department said.

He lives near campus and could be on school grounds at any time, the website says.

Anyone who sees Doyle is urged not to make contact and is asked to immediately call 911.

Doyle hasn't been charged with a crime.
