IOWA CITY, Iowa (AP) - Miya Rodolfo-Sioson, the only survivor of a shooting rampage at the University of Iowa in 1991, has died of breast cancer.

She died on Wednesday at a hospital in Oakland, Calif. She was 40.

A spokeswoman for the Alameda County Medical Center-Highland Hospital says Rodolfo-Sioson was being treated for stage four breast cancer, the most serious stage.
