Tack. Håller med om din tolkning, verkar förnuftigt.
Druid (som jag jobbade med en gång i tiden när jag var liten och ung) var påläst och duktig, men ingen kiselalgsexpert då för hundra år sedan vad jag visste om. Han kan dock säkert mycket om detta idag. Frågan är om hans utsago som endast innehåller flytande uttalanden om sannolikhet (utan procentangivelser) verkligen kan användas för att fälla någon för mord utan andra bevis?
Här är det enda jag hittat om hans forskning (från KI 140324):
Diatom studies
Henrik Druid's Group
This project aims at improving the diagnosis of drowning. Certain species of diatoms in the water that enter the lungs can cross the alveolar-capillary barrier and will be distributed to, and trapped in the capillaries of, remote tissues via the blood circulation. These diatoms can then be extracted from tissue samples and analyzed microscopically. A collaboration with Stockholm University has been established, and different tissues from drowning victims, and pertinent reference water samples, collected by the police, are studied both with conventional light microscopy and with Scanning Electron Microscopy (SEM). SEM allows for a more detailed identification of different diatom species than conventional phase-contrast microscopy. A bulk of papers has in the past addressed the feasibility of diatom analysis as an ancillary method to lend support to drowning diagnosis in decomposed cases, but the exact species identification has obviously hampered firm conclusion, making the methodology subject to substantial critizism. The aims of these studies include assessment of various extraction protocols, and evaluation of the efficacy of species identification with SEM and phase-contrast microscopy, respectively. The studies also include assessment of the need for ancillary methods in the medico-legal investigation, which is conducted by reviewing all bodies found dead in waters, regardless of assigned cause of death diagnosis.
