I think back to the line "MF DOOM, he's like D.B. Cooper" off of Hoe Cakes on the album MM..FOOD. He always was an enigma, and I guess having your passing be a secret for that long, for someone that influential, in the age of social media, just goes to show that it wasn't just an act.

Seems like very suitable for his character. Anyway, this is a big loss...
