POLICE will today continue the search for the missing babies born out of an alleged incestuous relationship between Delmas brother and sister Heibrecht and Robert Fedder, after finding nothing on the farm Witklipbank near Delmas yesterday. The excavations at two sites on the farm formed part of the investigations in the case, in which police arrested the Fedder siblings and their parents, Robert, 65 and Elsina, 60, after being tipped off by a family member. All four are out on bail, and stood in front of their house and watched as the police dug at the sites.
