Authorities seized 92 pounds of heroin valued at more than $870,000 from an 81-year-old woman attempting to smuggle the drugs across the U.S.-Mexico border. KABC-TV reports a U.S. Customs and Border Protection detector dog Wednesday at the Tecate border crossing alerted officers to the driver-side rocker panel of the 2011 Chrysler 200 the woman, an American citizen, was driving.
