DNA analysis was performed using microsatellite DNA
methodology. It was carried out by two different laboratories that
analyse ALSO modern DNA. They are ISO 9001 certified
laboratories whose performance and quality are beyond
discussion. All the recommendations of the International Society
for Forensic Genetics have been followed, including analysis of
negative controls. A “laboratory designed for ancient DNA
manipulation” is strictly necessary in the case of mitochondrial
DNA which is particularly prone to contamination. In our case
nuclear DNA was available which was fairly well preserved.
