The 25,000 missing persons in Mexico's war on organized crime remains "an open wound" for their families that the government must heal, Alicia Calderon, director of a documentary on the subject, said.

"A truth commission would be a first step toward solving all these cases. We have to fight to make the government come up with specific policies, because it has the obligation to heal the wounds it inflicted," the journalist said in an interview with Efe.

"Retratos de una Busqueda" (Portraits of a Search) shows the battle of mothers trying to discover the whereabouts of sons and daughters who went missing in the war on organized crime.

During the six years of his 2006-2012 term in office, ex-President Felipe Calderon of the National Action Party, or PAN, waged an all-out war against the drug cartels in which some 65,000 people died and another 25,000 are still missing.

That being the case, the film director considers that current President Enrique Peña Nieto of the Institutional Revolutionary Party, or PRI, should take action to compensate for the harm the government caused during that war over the past six years, regardless of which party is running the government.

"We're obliged to do so because the problem doesn't go away with the departure of Felipe Calderon - we've hardly begun to account for what happened," Alicia Calderon said.

The director is seeking financing to wrap up production of "Retratos de una Busqueda," which she hopes to premiere during the second half of 2013 and which will compete in the next Morelia International Film Festival.
