Mrs. Negishi, from Japan, is married to the Nobel Chemistry laureate Ei-ichi Negishi.
A Japanese Nobel-winning chemist has been found wandering in rural IL and his wife found dead nearby, some nine hours after they had been reported missing from their home 320km away.
When Ei-ichi was taken to a local hospital, police learned the couple's family had reported them missing the day before. His wife, Sumire Negishi, was also missing.
Deputies later found the couple's vehicle and the body of his wife, Sumire Negishi, at the nearby Ochard Hills Landfill, the sheriff's department said. Consulate officials say they have not been contacted by Negishi's family.More news: Rally 4 Tears Up The Track On Nintendo Switch
The sheriff's department says foul play is not suspected, but wouldn't discuss autopsy results. Local authorities in IL are now leading the investigation.
Negishi and another Japanese scientist Akira Suzuki, along with American chemist Richard Heck, professor emeritus at the University of DE, shared the 2010 Nobel Prize in chemistry for their work on reactions to create complex organic compounds. Eiichi was reportedly dehydrated and confused when he was transported to a hospital for treatment.
We will continue to follow this investigation as details develop.
