Distaso spent much of his time hitting hard on Peterson's affair with Frey - the woman whom he called "sweetie" and promised "our relationship will grow" in phone conversations recorded after she began helping police, conversations which prosecutors played Tuesday afternoon.
Distaso used a slide presentation to show numerous pictures of the two, often embracing and smiling - then interchanged those photos with pictures of Laci and Scott Peterson together, also smiling and embracing.
Peterson began his affair that fall. When Frey learned through news reports of Laci Peterson's disappearance that her boyfriend was married, she faxed a photo of her and Scott Peterson to the Modesto police.
A detective confronted Peterson with the photograph.
Peterson again denied the relationship.
"He says, 'Is that supposed to be me?"' Distaso said of Peterson's reaction.
Denial was part of Scott Peterson's style, Distaso suggested.
Earlier in December, a friend of Frey's confronted Peterson after learning he was married.
"He becomes very emotional," Distaso said. "He says, 'I lost my wife ... But I still tell some people that I'm married ... But I've lost my wife and this is going to be my first holiday season without her."
In January he contacted a realtor about selling the house, but told the realtor it had to be kept quiet(from taped conversation)
He did sell her car in January as well.
He was late to the town candle-light vigil, because he was on the phone with Amber--telling her that he was in Brussels.
