A gunman murdered two women in a Delaware courthouse Monday before police shot him dead, officials said. "A lone gunman walked into the lobby area and opened fire. Two civilian females were killed in the shooting," a police spokesman in the town of Wilmington, Delaware, told a televised news conference, AFP reported. Police officers on duty engaged the shooter and two were wounded before the shoot-out, involving "multiples" of bullets, at the New Castle county court building ended.
