 After the death of Dillema, a forensic test on body cells obtained from her clothing found that there was a Y-chromosome in Dillema's DNA, which indicated she was possibly a genetic mosaic or a true hermaphrodite.Most of the other women on the team at the time suspect it was an attempt by Blankers and Blankers-Koen to eliminate an opponent, although this has never been confirmed.The same year, Blankers-Koen almost repeated her Olympic performance at the European Championships in Brussels.
