They paused, to remember and say thank you.
Last year, there were 105 state troopers killed in the United States while working in the line of duty. As of May 16, there have been 45 this year.
In 1988, one of the troopers killed was Johnny Edrington of Campbellsville. And each Memorial Day, KSP Post 15 officials organize a service to remember Edrington.
KSP Public Affairs Officer Billy Gregory said the purpose of Friday's ceremony was to pause and remember Edrington's life and say thanks for his service.
