Every year thousands of migrants risk their lives crossing the Mexican desert with the goal of entering the United States. Today's edition of "Rear Window" looks at the saga of one migrant, Dayani Cristal who embarked on such a journey, through an interview with filmmaker and director Marc Silver. His documentary "Who is Dayani Cristal?", featuring renowned Mexican actor Gael Garcia Bernal, starts with the discover of a body in the Arizona desert whose only identifiable mark was a tattoo saying "Dayani Cristal" and follows the investigation from the migrant's hometown in Honduras to the place where his dead body was discovered. teleSUR
