In July 1984, Rosenkranz' wife Edith was kidnapped at the summer North American Bridge Championships in Washington, D.C., by Glenn I. Wright and Dennis Moss, and ransomed for one million dollars. The FBI and the District of Columbia police captured Wright and Moss, and she was returned safely. The ransom money was later recovered and the two kidnappers were later convicted and sentenced, as was a third defendant, Orland D. Tolden. Wright was released in 1999, Moss in 1994, and Tolden in 1989.
