Overview

• Tenente colonnello Andrea Berti filed a 300-page Bloodstain Pattern Analysis based on a 3D reconstruction that concludes there is no evidence of a second active assailant.
• The consultancy remains in the Procura di Pavia’s investigative file and is reportedly not shared with defense or civil parties, a handling described in coverage as unusual.
• Investigators note that BPA detects active participants only, so the finding does not exclude the possibility that another person was present without taking part in the attack.
• A separate appointment tasks Prof.ssa Cristina Cattaneo with determining the likely weapon, the number of wounds, and whether one or more perpetrators acted.
• The incident probatorio continues with eight digitized partial fingerprints for analysis by court expert Domenico Marchegiani, while disputed fingernail DNA profiles remain unresolved and a September 26 hearing will address the path of further testing.
