Samenvatting
Dit boek bevat bijdragen van wetenschappers uit het vakgebied van forensisch onderzoek. Zij geven u informatie over de huidige stand van de technologieën die gebruikt worden bij sporenonderzoek. Dit materiaal is vaak het bewijs dat de vermoedelijke dader op de plaats delict is geweest. Met veel cases uit de praktijk illustreert dit boek zowel de traditionele als nieuwe vormen van het onderzoek naar bewijsmateriaal.
Het boek behandelt:
- diverse methodieken, zoals massa spectrometrie, Raman microspectrometrie, statistische onderbouwing en nog veel meer;
- het analyseren van onder andere inkt, spermaresten, vezels, gebroken glas, contacten met airbags;
- Chemische opsporing van in eerste instantie onzichtbaar bewijsmateriaal, zoals bloedvlekken, vingerafdrukken en pepper spray.
Dit boek is vooral bedoeld voor wetenschappers werkzaam in forensische laboratoria over de hele wereld. Daarnaast is het fascinerende literatuur voor onder andere misdaadauteurs, advocaten, misdaadjournalisten.
