(FOX NEWS) - Two retired California detectives are returning to duty to solve a case that has haunted them for two decades: the savage rape and murder of a 22-year-old college student days before her graduation.
Debbie Dorian, an econonics students at Fresno State University, was found gagged, raped and murdered inside her north Fresno apartment in 1996. DNA collected at the scene was later linked to similar crimes in the Visalia area -- which occurred between July 1999 and August 2002 -- but no arrests have ever been made in Dorian's killing.
Now, 20 years later, Bob Schiotis and Vince Zavala, the two detectives who worked the case from the beginning, will review old leads and consider new ones, with the assistance of advances in DNA technology, the Fresno Bee reported.
The announcement was made at a news conference Friday by Fresno police Chief Jerry Dyer, who was joined by the two detectives and Dorian’s mother, Sara Loven.
Dorian's life "was cut short by evil people who caused her much pain," Loven said.
"The person or persons who killed my daughter are still free and continue to harm young women," she told reporters, according to the newspaper.
