New forensic evidence in the 2007 murder of Chiara Poggi has complicated rather than resolved the long-standing investigation. DNA analysis of cloth swabs used to collect samples from the victim’s palate, tongue, and oral cavity has revealed a male genetic profile that remains unidentified—yet falls short of proving multiple perpetrators were involved.
The discovery emerged from an evidentiary hearing ordered by Pavia prosecutors, refocusing attention on Andrea Sempio—a friend of the victim’s brother—who stands accused of complicity. This development could potentially overturn years of legal proceedings that resulted in the conviction of Chiara’s then-boyfriend, Alberto Stasi, who is completing a 16-year prison sentence.
Genetic testing conducted by court-appointed expert Denise Albani confirmed prior results: three of five swabs yielded no usable evidence, while two revealed distinct Y chromosomes. One matched Ernesto Gabriele Ferrari, assistant to autopsy pathologist Dario Ballardini. The second, attributed to “Unknown Male 3,” excludes both Sempio and Stasi as sources.
Forensic consultants remain sharply divided on interpreting this genetic trace. Some describe the profile as “clear, complete, robust with 22 markers” and genuinely unidentified. Others, including defense consultant Luciano Garofano (former head of Italy’s Carabinieri Scientific Investigation Unit), argue it represents minimal contamination blending Ferrari’s DNA with another unknown individual.
Garofano asserted the “logical, non-partisan explanation” involves contamination occurring before sample collection via mishandling of the cloth swab—a theory he claims invalidates the “second man” hypothesis as “chasing a phantom.”
In her latest report, Albani indicated she will demand explanations from Ballardini regarding his use of potentially non-sterile fabric instead of standard swabs, plus detailed records of personnel present during the autopsy and subsequent body handling.
If the unknown profile remains unidentified, investigators may retest previously excluded individuals. With no matches to Poggi family associates, potential subjects range from funeral home staff to Red Cross responders present on August 13, 2007, and forensic photographers.
Separately, an ex-officer’s attempt to sell crime scene photos online has sparked public outrage. Italy’s privacy regulator blocked distribution, marking another painful violation against the murdered woman and her family 18 years after the crime—with potential legal action pending.
