Basweti was suspended in early 2013 (retroactive to July of 2012) after testing positive for performance enhancing drugs:

. His ban ended this past July. Before his ban, he was a prolific marathoner.
Results from the McAllen race (which surely doesn't have drug-testing) are here:

. (It defaults to the half marathon results, so you'll have to change the division and run another search).
He only ran 2:40, but per the event website, he took home a $750 first-place prize:

. (Where were you, LetsRunners?)
Looks like he's cherry-picking low-hanging races without testing. He seems like a great guy for some targeted testing (although there are admittedly bigger fish to fry).
