The woman who introduced Scott Peterson to his mistress, Amber Frey, called him a womanizer, a liar and a cad during testimony in his double-murder trial Wednesday.
Under questioning from prosecutors, the woman, Shawn Sibley, explained that Peterson said nothing about being married when they met, insisting instead that he was looking for a long-term, serious relationship.
Peterson, 31, is on trial for allegedly murdering wife Laci and their unborn son on or around Dec. 24, 2002, and dumping the remains into San Francisco Bay. The former fertilizer salesman has pleaded not guilty to all counts.
Sibley said she met Peterson at a fertilizer industry trade show in October 2002, and told her he'd had a lot of one-night stands, "but all the women he met were bimbos with no
brains." He wanted to find someone with intelligence, and asked Sibley, who was engaged, if she had any friends he could "hook him up with."
Sibley testified that she set up the first date for Peterson and Frey, babysitting
Frey's daughter while the massage therapist stayed out all night. But then on Dec. 6, a co-worker of Sibley's mentioned to her a Scott Peterson from Modesto who had a pregnant wife.
"I freaked," Sibley told the court. "I freaked because I had set him up with Amber."
In cross-examination, defense attorney Mark Geragos tried to portray Peterson as an average married man.
"Did you ever know a married man to act idiotic?" Geragos asked Sibley.
"Yes, but I've never known a married man who lied to me about being married," Sibley parried.
Court resumes next Tuesday after a break for the holiday weekend.
