On August 20, 1986, 33-year-old Paul Michael Rockne was one of fourteen people killed in the mass shooting at the Edmond, Oklahoma post office. Rockne worked there as a letter carrier for the United States Postal Service. The gunman was a 44-year-old coworker, Patrick Sherrill.

The next morning he entered the post office shortly after 7:00 a.m. armed with three pistols and a mailbag full of ammunition. He first shot one supervisor, then searched for the second supervisor, Bill Bland, who was not at work because he had overslept. Sherrill encountered and fatally shot Paul Rockne and continued through the building for about fifteen minutes, killing fourteen people and wounding six others before shooting himself in the head as police were entering.

Paul Rockne was the grandson of Notre Dame coach Knute Rockne. The shooter’s suicide meant there was no criminal trial in the case. Did anyone who worked at or lived near the Edmond post office remember unusual behavior from Sherrill or anything that morning?
