Walter Simon Notheis Jr., 40, a singer from St. Peters, Missouri who performed as Walter Scott with the 1960s band Bob Kuban and The In-Men, vanished in late December 1983 after being last seen the evening before he was reported missing on December 28. For years his disappearance remained unresolved.

In April 1987 his body was found in a cistern on property that had belonged to James Howard Williams Sr. Investigators determined Notheis had been bound with a rope and shot in the back; his death was treated as a homicide. Authorities arrested and charged his wife, Joann Marie Notheis, and her boyfriend, Williams, in connection with the killing. Williams was convicted on two counts of capital murder and later sentenced to life without parole; Joann pleaded guilty to hindering prosecution and received a five-year sentence. Williams later died in prison and Joann died in 2019.
