Testimony is set to resume Friday in what is expected to be the last day of the preliminary hearing for a Northern California serial killing suspect.
During the seventh day of testimony on Thursday, the ex-wife of a Joseph Naso, Judith Naso, told the court that she may have twice been drugged unconscious during her marriage so she could be sexually assaulted by strange men.
Judith Naso said she remembered two nights in 1976 when she mysteriously passed out after taking "vitamin pills" given to her by her husband, defendant Joseph Naso, who is representing himself in the murder case.
He has pleaded not guilty to murdering four women — Roxene Roggasch, Carmen Colon, Pamela Parsons and Tracy Tafoya — in the 1970s and 1990s and dumping their bodies in rural areas.
At the conclusion of the preliminary hearing, the judge in the case will decide whether there is enough evidence to try Naso on the four counts of murder.
Judith Naso, 73, testified that on one occasion, she woke up in her Piedmont home with a strange man on top of her and later learned the stranger had been a hitchhiker picked up by her spouse.
"He would give me what he told me were vitamin pills," she said. "He said they would help my headache."
She said on another occasion after a night out in San Francisco, she awoke in a hotel room with two strange men hovering near the bed.
"It was almost dreamlike," said Judith Naso, who divorced her husband in 1980. The couple had two sons.
Marin County prosecutors sought to present evidence that Joseph Naso drugged his victims, sometimes photographing them in pictures where they appear dead or unconscious.
In previous testimony, investigators said they found DNA that matched Judith Naso's profile on a pair of nylon stockings used to strangle Roggasch in 1977.
Judith Naso told the court that her ex-husband tried to get her to lie about the nylons, sending a letter last year telling her to say she might have left her pantyhose in a public place or at work.
Joseph Naso objected to his ex-wife's remembrances of the possible drugging.
"The events of our marriage are sacred and private and have nothing to do with this case," he said.
