Manhunt intensifies in US after lawmaker killed, another wounded

As the search stretched into its second day, police appeared to close in on the shooter, finding a car described as related to him, but not the man himself. America reeled from its latest spasm of political violence as lawmakers called for a return to civility in political discourse that has been overheated and angry for years. Authorities searched for a man identified as Vance Boelter, 57, who also allegedly shot and wounded another lawmaker and his wife early Saturday in the northern state bordering Canada.
