Maria Santos holds a picture of her son Dervin Gomez, who went missing on March 2010 while making his way from Mexico to the U.S., in a shelter for immigrants "La 72", named in honour of 72 migrants killed in 2010 in San Fernando, north of Mexico, in Tenosique, Tabasco, in the south border of Mexico, December 2, 2013. The group, made up of relatives of people who went missing while making their way to the U.S., marched from Guatemala to Mexico to demand that the governments of Mexico and Central America stop kidnappings and crimes committed by organised criminal groups against migrants, according to the organisers.
