“Joe Koenig remains one of the most accomplished investigators the Michigan State Police has ever had in its ranks. This is a complicated news story dating back to November 24, 1971. Joe Koenig spent considerable time traveling throughout the country, interviewing those who knew Walt Reca. I believe that Joe, with extensive and meticulous work, has without question identified Walt Reca as D. B. Cooper.”
—Col. R. T. Davis, Retired Director, Michigan State Police
