AFAIK,
AA is anonymous, thus the name "Alcoholics Anonymous."
However,
we have the example of a chronic alcoholic who died of cancer to the eye AND LIVER.
(Between the alcohol and chronic tobacco abuse, we have exposure of the liver to something
known to damage it, and something known to cause cancer.)
We have the example of someone who plagiarized everything he came across-
who seems to have plagiarized AA.
That's not an eyewitness account, but the circumstantial evidence is sufficient for most
people to connect the dots there-
except for the usual "wierwille was a giant among men and you all suck for pointing
out all his issues" crowd.
