Almost a month after a pregnant Modesto woman disappeared, her husband has brought the search for Laci Peterson to Southern California. Scott Peterson and supporters opened up a volunteer search center at a West Los Angeles hotel yesterday to distribute fliers, posters, buttons and information on a reward for finding the 27-year-old woman. Although police have not labeled her husband a suspect, investigators are looking into reports he was having an affair. Scott Peterson denied the report in an interview with a television reporter Friday. In Los Angeles, Scott Peterson declined to answer any reporters´ questions about himself. He said: “The only thing to put in front of the media is her picture and description.”Peterson said he would take the search to San Diego next weekend and continue expanding it until his wife is found. Meanwhile, sheriff€™s investigators in San Luis Obispo County say Scott Peterson is not a suspect in the disappearance of a 19-year-old student seven years ago. Peterson and his future wife Laci both attended Cal Poly-San Luis Obispo at the same time that Kristin Smart disappeared.
