On Aug. 4, 1997, Fiona Yu, 21, was sexually assaulted and strangled by an attacker at her apartment in Tempe.
Yu, who was an Arizona State University senior studying accounting, was last seen by her neighbor about 4:30 p.m., when she was riding a bicycle around her residence, police said.
About 90 minutes after, her roommate found Yu barely alive on the second floor. She later died of her injuries.
Tempe police detectives tracked down a few possible suspects but soon realized their DNA testing did not match a DNA sample collected at Yu's apartment.
