Spencer was a pilot who operated out of Nightmute, Alaska. When detectives Will Dormer and Hap Eckhart were brought in from Los Angeles to investigate the murder of Kay Connell, Spencer flew them in. On the way, he warned them that it would get bumpy several times.
When Randy Stetz was arrested for the murder and Dormer was to return home, Fred Duggar joked that it was conditional on Spencer remembering where he parked the plane.
