This interview is 4 years old but I only saw it today. Victor Conte was talking about this 'Memo' guy on Twitter. After a bit of googling I found this interview with Angel 'Memo' Heredia
A lot of people have probably seen this already but anyways...
Heredia was a 'dealer' who supplied athletes with what they wanted. During the time of this article she was under investigation and entangled in the court system with various allegations.
Angel Heredia, once a doping dealer and now a chief witness for the U.S. Justice Department, talks about the powerlessness of the investigators, the motives of athletes who cheat and the drugs of the future.
He had been in hiding under an assumed name in a hotel in Laredo, Texas, for two years when the FBI finally caught up with him. The agents wanted to know from Angel Heredia if he knew a coach by the name of Trevor Graham, whether he carried the nickname “Memo”, and what he knew about doping. "No", "no", "nothing" – those were his replies. But then the agents laid the transcripts of 160 wiretapped telephone conversations on the table, as well as the e-mails and the bank statements. That’s when Angel "Memo" Heredia knew that he had lost. He decided to cooperate, and he also knew that he would only have a chance if he didn’t lie – not a single time. “He’s telling the truth,” the investigators say about Heredia today.
SPIEGEL: Mr. Heredia, will you watch the 100 meter final in Beijing?
Heredia: Of course. But the winner will not be clean. Not even any of the contestants will be clean.
SPIEGEL: Of eight runners ...
Heredia: ... eight will be doped.
SPIEGEL: There is no way to prove that.
Heredia: There is no doubt about it. The difference between 10.0 and 9.7 seconds is the drugs.
