Captain Walter Lee Peterson, a guard at Western Penitentiary, was killed by inmate Stanley Hoss in a racially-motivated attack on December 10, 1973.
Hoss, a former death row inmate whose sentence had been commuted to life imprisonment, was convicted of first-degree murder for killing Peterson and received a second life sentence. Hoss was originally sentenced to death for killing Verona Police Officer Joseph Zanella on September 19, 1969.
Stanley Hoss hanged himself in prison on December 6, 1978.
