Totally agree with Oscar. This whole thing has ALWAYS been over thought by too many people, including Hubbard, dukerdog, SOKLR, and even the writer who did the interview.
The sleuthing that went on to find photos and over whelming evidence that he did cheat was some very good work by about a dozen or so people. But the how and why stuff is ridiculous.
Why did Ruiz cheat? To brag that she ran faster than she could but unfortunately she went too far. For this guy Litton to do it all over the country is not hard to figure out. Who knew him in Florida and other states that he ran in? In Michigan he would have eventually ran out of races as someone would see him at the start, who knew him or of him, and then also see him at the finish in a different outfit. Pretty soon it would get to be "unexplainable".
He has money so he does it out of state. He then gets an article written about him and his running a few years ago in Michigan and pop goes the ego. Believe me, whoever works for him has access to google and knows that he cheated.
What really nailed him was technology, from LR to YouTube to actual race websites with photos and splits. Without those things he would have had fewer suspicious races.
