Waller, 58, was arrested Thursday when he arrived for work at U.C. Berkeley.

"The answer has always been in the DNA," said Sacramento County District Attorney Anne Marie Schubert. "For 27 years there has been one common thread, his DNA. I have often said in my career that DNA is the silent witness to the truth."

Investigators say they obtained two samples of Waller's DNA and matched it with samples left at various crime scenes, including during a 1997 attack in Chico.

A Sacramento rape victim sacrificed her privacy in hopes it will help catch a sexual predator.


"The DNA in our case comes from her stabbing the defendant in the arm," explained Michael Ramsey, the Butte County District Attorney," and the man that tried to clean up the crime scene was unsuccessful."

"It was a typical Halloween night with a person handing out candy," recalled Contra Costa County District Attorney Diana Becton, gratified that the charges against Waller include a 1996 attack in Martinez. "It is a very good day for law enforcement and for the victims of crime when we can finally hold someone accountable."

Waller is married and has held the same job at U.C. Berkeley for 25 years.

He's now being held at the Sacramento County jail without bail.
