Ferndale Senior Center residents debated new Channel 27 Action News anchorwoman Sonya Luntz's ethnicity for a fifth straight day Friday, with Edward Bloch, 81, steadfastly holding to his 'Mexican' theory and Muriel Simmons, 83, leaning toward Hawaiian or Indian. 'If you ask me, she looks Oriental,' said Jack McCallum, 79, watching Luntz on the 6 p.m. newscast. 'Orientals have that shape to their faceI saw it in the war.' Luntz's ethnicity will be put to an official senior-center vote this Thursday.
