ROCKFORD, Ill. (AP) — Family members say a Nobel Prize-winning Purdue University chemistry professor was confused and searching for help when his wife's body was found at a northern Illinois landfill. The relatives told WTHR-TV in Indianapolis that 80-year-old Sumire Negishi (soo-MEE'-la nah-GEE'-shee) was "near the end of her battle with Parkinson's" disease and was traveling with her husband, 82-year-old professor Ei-ichi Negishi (aich nah-GEE'-shee). The Ogle County Sheriff's Office said deputies found Sumire Negishi's body and the couple's vehicle Tuesday at Orchard Hills Landfill outside Rockford.
