Scott Peterson was charged with the murder of his pregnant wife Laci Denise Peterson and their unborn son Conner Peterson who disappeared sometime between Dec. 23 and Dec. 24, 2002. The badly decomposed remains of Laci Peterson and the couple's fetus washed ashore in April 2003, not far from where Peterson said he went on a solo fishing trip the day she vanished.
Laci Peterson, 27, of Modesto, Calif., was eight months pregnant when her husband reported her missing on Dec. 24. Scott Peterson, 30, was arrested April 18 and is being held without bail on two counts of murder. He could face the death penalty if convicted.
