Double Homicide in Aigio: Unidentified DNA and Third Forensic Examination at Crime Scene

—

in

Two weeks have passed since the bodies of a 54-year-old woman and her 26-year-old son, Olympios, were discovered inside their home in Longos, a suburb of Aigio in western Greece. Investigators continue piecing together the puzzle of this double homicide—a case that keeps revealing new, often puzzling, details.

Man in Custody Maintains Innocence

A 65-year-old Italian man—longtime partner of the deceased woman—has been remanded in custody. He is charged with both murders. Arrested two days after the crime came to light, he continues to deny involvement, claiming instead that mother and son killed each other.

Investigators Remain Convinced of His Guilt

Nonetheless, police investigators believe he is the sole perpetrator. They deem it physically implausible that the 54-year-old woman could have stabbed her son multiple times and then taken her own life with over 20 stab wounds.

Mysterious Absence of Forensic Evidence

As days pass, the case grows increasingly complex. No genetic material or fingerprints belonging to the suspect have been found at any of the crime scene locations. Initial forensic analysis by Hellenic Police labs revealed no fingerprints of the 65-year-old on the knife used in the attack. On the firearm used to shoot the 26-year-old, however, DNA from an unidentified third person was detected.

Investigators suspect the suspect cleaned the crime scene thoroughly—using bleach and alcohol—after committing the killings. They also believe he deliberately delayed reporting the deaths: he reportedly asked a neighbor to contact authorities hours after the murders, possibly to buy time for the cleanup.

Third Forensic Visit Yields New Samples

On 17 June, forensic experts from the Hellenic Police’s criminal investigation laboratories visited the house for the third time. They collected additional blood samples from newly identified traces—samples still undergoing laboratory analysis.

Defense attorneys for the suspect point to significant gaps and unanswered questions in the prosecution’s case. All forensic findings will be independently reviewed by their own expert witness before trial.
