UNDATED PHOTO: This undated photo shows Laci Peterson who has not been seen since December 24, 2002. Peterson, 27, who was eight-months pregnant, allegedly went to walk her dog in a nearby park on Christmas Eve morning and has been missing ever since. The Modesto Police published several images of her husband Scott Peterson's truck and boat on their Web site in order to "corroborate" his alibi that he had gone on a solo fishing trip.
