Alfonso Portillo served as President of Guatemala from 2000 to 2004. In January of 2010 he was captured and arrested on charges of embezzlement. He is also wanted in the US for allegedly embezzling foreign donations for education projects. But under Guatemalan law, he must be tried in his own country before he can be extradited. He is currently being tried in Guatemala City.
A recent report from his trial was posted on Forbes.com this past week.
