The biostatistical analysis conducted by geneticist Denise Albani of the forensic police office, and expert appointed by the preliminary investigations judge of Pavia Daniela Garlaschelli in the evidentiary incident in the investigation into Andrea Sempio for the murder of Chiara Poggi , indicates that there is "full concordance" between the Y haplotype detected in 2007 on two of the victim's nails and the paternal line of the biological profile of the suspect : a population of very few people that is reduced to relatives in the male line.
This was reported by "Il Corriere della Sera", "La Repubblica" and Il Messaggero" according to which the certified email sent by the expert Denise Albani arrived late yesterday morning in the email inboxes of the parties' consultants and the public prosecutor's office.
A conclusion that, according to the newspapers, by investigative logic, leads directly to Sempio, 38, a youthful friend of Marco Poggi, the victim's brother.
The advance will be crystallized in the final report that Albani will submit at the beginning of December and which will be discussed at a hearing in Pavia on the 18th.
The result overturns what geneticist Francesco De Stefano, an expert witness for the second Court of Appeal that convicted Stasi eleven years ago, had established: the professor analyzed and discarded the same DNA because it was "not consolidated," also providing the scientific basis for the initial dismissal of Andrea Sempio's case, requested in 2017 by then-adjunct prosecutor Mario Venditti, now under investigation for corruption in judicial documents.
Albani's investigations established that De Stefano's laboratory tests were conducted with non-homogeneous samples, but "in the 5 microliter session a mixed partial haplotype emerged for a total of twelve" markers.
Albani emphasizes that "the haplotype is not in itself identifying, therefore it is a Y chromosome, it is shared by all subjects related on the paternal line, therefore it cannot be uniquely attributed to a single person", rather "it is a family context of belonging".
