Yeah, I think trying to twist it into a race thing is complete and utter horseshit from a money-grubbing family. The sample was from a routine tissue biopsy that would be taken from patients of any race in the process of trying to diagnose their cancer. That it happened to be such a rare . maintainable line and she happened to be black were coincidences. The family should have been told to pound sand.
Also, by odd coincidence, the OP’s last post was 3 years ago today.
And of course, they did a Law & Order episode based on this.
