Still no new leads in the search for missing 27-year-old Laci Peterson.
A state crime lab is analyzing material found during the investigation into the disappearance of the pregnant Modesto woman. Authorities would not say whether the material is blood, saliva or semen. Nearly a dozen divers scoured areas of Lake Tulloch the past two days, but their search turned up nothing.
Peterson, eight and a half months pregnant, has been missing from her Modesto neighborhood since Christmas Eve.
