Sharon Rocha, mother of Laci Peterson, leaves the San Mateo Courthouse during the lunchbreak in the Scott Peterson murder trial in Redwood City, California, August 10, 2004. Peterson's mistress testified on Tuesday the accused wife killer seduced her with champagne and slow dancing just weeks before his pregnant wife was murdered and dumped in the ocean. In her long-awaited testimony, Amber Frey said Peterson assured her he was single as he wooed her with strawberries and champagne, sang karaoke and paid extra for a private booth in a sushi bar. Peterson faces a possible death sentence if he is convicted of murdering his wife, Laci, and their unborn son. REUTERS/Lou Dematteis LD/GN
