Police say they do not plan more searches in Berkeley for a missing pregnant woman from Modesto — unless new leads take them back to the area. Police say they are still looking for Laci Peterson, but they declined to say exactly where they are searching. Peterson disappeared Christmas Eve. Her husband says he was fishing near the Berkeley Marina at the time. He reported his wife missing after he returned home. On Saturday, volunteer divers spent hours searching the bottom of San Francisco bay, but they found only an old boat anchor. Peterson was eight months pregnant when she vanished.
