Walt Staton is an activist who volunteers with No More Deaths, a humanitarian group that helps migrants who are in trouble in the desert just north of the U.S./Mexico border. He was cited for littering by the US Fish and Wildlife agency when agents found him placing water jugs for migrants in the desert. He was convicted by a jury in July 2009 and sentenced in August.
13 more volunteers have since been cited with the same charge. Their trial is set for January 2010.
