Officials of the Mexican government appealed to three Colombian Police retired generals for assistance in the closure of issues relating to Guzmán, according to a report dated to 1 August 2015. Among them is Rosso José Serrano, a decorated officer and one of the masterminds behind the dismantling of the Cali Cartel and Medellín Cartel and Luis Enrique Montenegro, protagonist in the arrests of Miguel and Gilberto Rodríguez Orejuela. They suggested particular Colombian strategies like creation of special search units ("Bloques de Búsqueda" or Search Blocs), specialized investigation and intelligence units, like DIJIN (Directorate of Criminal Investigation and Interpol) and DIPOL (Directorate of Police Intelligence) and new laws about money laundering and asset forfeiture. After the third capture of Guzmán, it was revealed that the Government of Colombia had sent a team of 12 officials to assist the Mexican authorities on tracking down Guzmán.
