No, organ harvesting has never been linked to missing Black Americans.
Not because organ sales aren't a market, but because the victims of organ harvesting are the same people who are already hyper-exploited throughout the Global South. The same people who are already labor and sex trafficked.
Killing and harvesting organs from middle-class Black people in the U.S. doesn't make sense from a logistical standpoint at all.
Kendrick Johnson mostly likely had his organs removed to hide the cause of death - not to try and sell them.
Jelani Day wasn't missing any organs, nikkas online started saying that to try and make his death "spookier" - but his mom came out and said it was a lie.
There's a desire to link it to missing Black people because simple answers aren't what news consumers want.
