Mitt Romney’s brother looked despondent as he strolled through the Southern California rain, days after his estranged wife was found dead at a nearby parking garage. George Scott Romney, 81, kept his head down and his face wrapped in a hood as the raindrops fell on his head Tuesday. He was going for a walk in the Valencia neighborhood where he lives in a $700,000 condo, and where neighbors say his late wife — 64-year-old Carrie — was often seen before they split back in June.
