Fitzco card (reference swatch from Simpson's blood)

Fitzco blood reference card prepared by Colin Yamauchi on June 14, 1994 from approximately 1cc of Simpson's reference blood tube. Sampled last in the DNA extraction sequence, after coin envelopes and the Rockingham glove. Used as a high-DNA-content exemplar; its proximity to evidentiary samples on the same workspace was challenged as a potential contamination source.
