A woman in Pennsylvania accused of killing at least four newborns to cover up an extramarital affair and storing some of the bodies in a cooler waived her right to a preliminary hearing. Michele Kalina of Reading faces one count of murder and other charges of abusing a corpse and concealing the death of a child. Authorities determined the four babies were killed in a manner consistent with asphyxia, poisoning or neglect. Police say she hid the remains of five babies, four of them born alive, in coolers or encased in concrete in her closet.
