Although Amelia, the last survivor of Hacienda Buena Vista, seemed to have consulted with the German consul of the time, Julius Lesse, about writing a document stating that her last wish was to have her body cremated and the ashes thrown into the sea; the same doctor Lesse and Carlos Enrique Reverón went up to Buena Vista, and injected the dose prepared for her 20 years before by Knoche himself, closing the door of the mausoleum afterwards and throwing the keys into the sea.
Three years later, in 1929, an expedition to the Knoche's family Mausoleum found that many of the mummies had been removed from their niches and were scattered on the ground.
Ever since, the Knoche's homestead has been slowly engulfed by vegetation and pillaged by vandals, looters and medical students, either seeking the secret of the embalming fluid or attracted by the myth of this dark work.
Some of the exterior walls, doorframes of the main entrance, stables, a tank, the laboratory and oven are all that remain of the place. To this day, the exact composition of the substance used by Knoche to preserve his corpses has never been discovered
