Milan, 27 November (LaPresse) – Biostatistical calculations on the possibility of a match between the genetic traces on Chiara Poggi's fingernails and Andrea Sempio's Y profile were carried out on a database of over 39,000 haplotypes in the Western European population. This is what LaPresse has learned from the tables sent yesterday by the expert witness, Denise Albani, to the defence counsels of the 37-year-old, Marina Baldi and Armando Palmegiani, of the Pavia Public Prosecutor's Office, Carlo Previderè and Pierangela Grignani, of the Poggi family, Marzio Capra, and to the defence geneticist Stasi, Ugo Ricci. To calculate the highest probability of origin of the profile identifying a partial and mixed male paternal line found on the fifth finger of the right hand and the first finger of the left hand of the 26-year-old woman killed in Garlasco on 13 August 2007, the expert used the reference database for haplogroup research in the forensic field called YHRD (Y-STR Haplotype Reference Database), which is the most comprehensive archive in existence. Worldwide, it contains 349,750 profiles, while the national “Italy” database consists of “only” 5,638 profiles. This number was considered too low – even by the consultants of the Pavia public prosecutors Napoleone-Civardi – to carry out the statistical investigation. The forensic expert carried out the probability calculation on the database called “Western European Metapopulation”, consisting of 39,150 profiles from Western European citizens. Using this system, it was deemed more likely that the traces on Chiara Poggi's fingernails were generated by Sempio and a second unknown male subject, rather than by two other unknown subjects with no links or connections to Sempio. With regard to the tables and calculations forwarded yesterday to the parties and not accompanied by comments or conclusions, the investigating magistrate of Pavia, Daniela Garlaschelli, wrote an email to the defence lawyers of the new investigation into the Garlasco murder to inform them of their right to submit “written reports” or “observations” in view of the final hearing on 18 December. Albani, on the other hand, will file her final report, including her conclusions, by 5 December. “I can never say, and I want to emphasise this, that that profile belongs to Mr X, because it is conceptually wrong, being an haplotype, regardless of the specific case,” the expert had already explained at the last hearing on 26 September.
