Dark Matter is an experimental exercise based on an excavation of the 54,000 pages divided into 85 volumes and 13 appendices of the "Iguala case," made public by the Attorney General's Office (PGR) in 2015. The set of documents presented in PDF format, illegible files, crossed out, photocopied, scanned, and photocopied several times. Until the disappearance becomes integrated into the document itself. The disappearance of the image. The disappearance of the text. Generations of images dissolved to the point of losing their status as images.
