The suspects — the 33-year-old nephew of the campground’s owner and a businessman friend from Athens – were arrested on charges of moral complicity, meaning they are accused of planning and directing the killings rather than carrying them out themselves.

According to the indictment, the nephew allegedly worked with his friend, who employed the two men believed to be the gunmen, to arrange the murders in order to gain control of the victim’s assets. Authorities estimate the value of the campground owner’s property at around €30 million.

Investigators believe the plan targeted both the 68-year-old owner and a 60-year-old employee of the business. The two victims were fatally shot inside the campground earlier this year.

The case is continuing to expand. Two women — the nephew’s partner and another close female relative — have been drawn into the investigation, with authorities examining what role, if any, they may have played in the events leading up to the killings.

An arrest warrant has also been issued for a third man, described as a 33-year-old associate of the businessman, who is currently abroad on vacation. Investigators note that the man recently sold his share of a business venture to his mother and brother, receiving approximately €900,000, a transaction now under scrutiny.

Authorities say the suspects are expected to present their defenses before the judge as the inquiry continues. Further charges are not ruled out as investigators work to determine whether additional accomplices were involved in the planning or execution of the crime.
