This article analyses how a new audio-visual format, the webdocumentary, deals with a problem related to drug trafficking in Mexico (disappearances and murders of women in Ciudad Juarez), in order to map the city and its criminality much alike a puzzle that can be freely interlocked. The idea is to provide meaning to a series of events considered from the perspective of catastrophe: tremendous, and lacking of significance. Based on traditional sources, the webdocumentary deals with unpublished material provided by a journalistic fieldwork that also gave birth to a book and a documentary. It is a triple investigation and revelation of a hidden reality whose violence spreads in the whole society. The troubling atmosphere of the webdocumentary appears to be an appropriate tool to report on this phenomenon.
