Jean had been living in Kato Gouves, a village about 12 miles (19km) from Heraklion, for a number of years at the time of her death.
She worked in several local bars and tavernas.
Her body was discovered on 13 March 2009, four days after she was reported missing.
The accused was questioned in January last year and was charged in November.
An initial post-mortem examination determined Jean had drowned, but a re-examination in 2019 later suggested injuries consistent with a struggle.
A fresh appeal on the Greek equivalent of Crimewatch in 2020 also failed to yield any new information.
In 2021, specialist officers working as part of a unit investigating organised crime also investigated to no avail, though did rule it was “foul play”.
The investigation was officially reopened in June 2024 after a private investigator hired by her son passed a 24-page report to Greek authorities.
