Gregorio "Greg" Sánchez, remember him? He was gubernatorial candidate in Quintana Roo in 2010, but was arrested by federal authorities on accusations of links to organized crime and for illicit enrichment.
Last August he was released from prison, though charges have apparently still not been dropped.
He notably spent the time writing 125 hymns to the lord - why of course, Greg is also a preacher and a born-again christian.
And now.. he wants to be a senator from Quintana Roo, running on the label of the Workers Party, the PT, which apparently backs his bid, as does AMLO.
Indeed the lord does move in mysterious ways.
