Latif turns his focus to Sudan, where his namesake spent time working on a sunflower farm. What could be suspicious about that?  Latif scrutinizes the evidence to try to discover whether - as Abdul Latif’s lawyer insists - it was just an innocent clerical job, or - as the government alleges - it was where he decided to become an extremist fighter.   This episode was produced by Suzie Lechtenberg, Sarah Qari, and Latif Nasser. With help from Niza Nondo and Maaki Monem. Fact checking by Diane Kelly and Margot Williams. Editing by Jad Abumrad and Soren Wheeler. Original music by Jad Abumrad, Alex Overington, Jeremy Bloom, and Amino Belyamani.  Support Radiolab today at Radiolab.org/donate.
