Sixteen hours after she was reported missing, the body of the American woman Christine Logan was discovered early Sunday, Dec. 19, between Mattan and Beit Shemesh southwest of Jerusalem, bound and bearing marks of extreme violence. Police have cordoned off the area and imposed a blackout on the investigation. Saturday afternoon an Israeli tourist guide, Kaye Susan Wilson, reported they had both been attacked by two Arabs, presumed Palestinians, deep inside the Green line near Mattan. The search now switches to the perpetrators.
