I posted a diary here about Dr. Jose Manuel Mireles here in July: Michoacán Autodefensa leader arrested and charged.
He is still incarcerated, and has health problems. Some polls taken in August showed that, if Mexico's next Presidential election was held now, Mireles would win with 80% of the vote.
There is now a petition on change.org to the UN Human Rights Commissioner calling for the release of Dr. Mireles. You can view and sign it here.
Facebook page for Unidos por Michoacán USA, one of many groups in support of Dr. Mireles.
