REDWOOD CITY, Calif. -- The woman who introduced Scott Peterson to his mistress testified yesterday that when she first met him, Peterson never mentioned that he was married and told her he had ''lost" his first love.
Peterson then turned the conversation to sex, Shawn Sibley testified.
''We'd be talking about something else and he'd bring up sex," she said. ''He did ask me my sexual preferences . . . sexual positions . . . but he was kind of joking."
She later introduced Peterson to his mistress, massage therapist Amber Frey.
Prosecutors say it was that affair that drove him to murder his pregnant wife, Laci, around Christmas Eve 2002.
Sibley said that when she met Peterson at an agriculture conference about two months earlier, he told her he was looking for a long-term relationship.
She said that after she learned he was married, Peterson initially denied it but later told her: ''I had been married. I lost my wife."
The trial was recessed shortly before lunch yesterday and will resume on Tuesday.
Sibley's testimony followed three days of cross-examination of detective Allen Brocchini by defense attorney Mark Geragos that methodically picked apart the police investigation into Laci Peterson's disappearance. Geragos attempted to show that police rushed to arrest Peterson while ignoring other leads.
Prosecutors allege that Peterson, 31, killed Laci, then weighted her body down with concrete anchors and dumped her body in San Francisco Bay. Scott Peterson was arrested four months after she vanished, when the partial remains of Laci Peterson and her fetus washed ashore 2 miles from where he said he was fishing.
