BALTIMORE — A Maryland woman whose death last year was blamed on an attack by a panhandler was actually killed by her husband and his adult daughter, police said Sunday. Keith Smith, 52, had told police that his wife, Jacquelyn, an engineer from Harford County, was trying to give money to a panhandler at a traffic light when she was robbed and fatally stabbed. Both were arrested in Harlingen, Texas, near the Mexico border. Harrison said the two were preparing to leave the country.
