About this Case:
Thomas Riha was a Czech born U.S. citizen who taught Russian history at CU Boulder in the 1960s.On the night of March 14, 1969, Riha went to a birthday party in Boulder, Colorado, where he told the host he thought he was being followed, but refused an offer to stay the night. After he left that night, his family and colleagues never saw or heard from him again. His passport and other personal effects were later found in the home of a person of interest, an ex-wife, who committed suicide in 1971. Following Riha's disappearance, there was speculation whether he might have been involved in espionage due to his background. Despite Riha being declared legally dead in 1978, he has never been found. Anyone with any information about this case is asked to please contact the Boulder Police Department.
