Overview
- Judge-appointed geneticist Denise Albani reports two nail traces showing correspondence with the Y-haplotype of Andrea Sempio or his paternal-line relatives, rated from moderately strong to strong on one hand and moderate on the other.
- Albani says the profiles are partial, mixed and degraded, making it impossible to determine which fingers they came from, whether DNA was under or on the nails, or how and when it was deposited.
- The report excludes other profiled men of interest, including Alberto Stasi, and quantifies support with likelihood ratios of roughly 476–2,153 for one trace and 17–51 for the other, based on non-local reference databases.
- Albani criticizes 2014 testing choices—no DNA quantification and differing eluate volumes—as limiting reliability of earlier evaluations and conditioning later analyses.
- An incidente probatorio is set for Dec. 18 in Pavia to question Albani and other experts; Sempio’s defense frames the findings as consistent with indirect transfer and investigators have also acquired newly surfaced 2007 photographs whose relevance remains uncertain.
