He is well known on campus. Someone remembered seeing him around 7:15 p.m. Sunday at the social sciences building, which is connected to the library, said Rick Shell, UAA police chief.

That night, Cheseto did not return to his apartment on 42nd Avenue, police said. His roommates are fellow athletes who reported him missing Monday morning to the coach, Michael Friess, said UAA athletic director Steve Cobb. On Monday, Cheseto didn't attend class. His teammates and coach checked his home and locker and found his winter coat, car keys and cellphone.

"He hasn't been seen from or heard from," Shell said. "It became worrisome."

Officials are concerned that he may have succumbed to the elements.
