Greek authorities have uncovered new evidence in the investigation of a double murder at a campsite in the coastal area of Finikounda in the Peloponnese, as police turn their attention to a possible third accomplice connected to the two suspects already in custody.

Officers conducted searches at several shops in central Athens where a 22-year-old man—now considered a potential collaborator—was employed. The businesses belong to a close friend of the nephew of one of the victims, a 68-year-old man who was killed in the attack and whose nephew is the only eyewitness.

During the raid, investigators seized documents and one or more computers that could contain critical information. According to sources, the 32-year-old shop owner had professional ties to one of the two jailed suspects and maintained a close friendship with the victim’s nephew, raising questions about possible links to the crime.

A journalist reporting on the case stated that the shop owner was asked to surrender his mobile phone to police in Thessaloniki, where he had been staying in recent days. Authorities are now analyzing all seized electronic devices.

Investigators are exploring whether the digital material includes social media content that could shed light on any connection between the new individual under scrutiny and the double homicide. The ongoing inquiry also extends to information originating from a village in northwestern Greece, which may hold relevance to the case.

Police and judicial authorities continue to piece together potential relationships among the suspects and witnesses as they seek to determine the full scope of involvement in the deadly attack.
