The naked body of Giuseppina Pasqualino di Marineo, 33, known as Pippa Bacca, was found in bushes near the northern city of Gebze on Friday.
She had said she wanted to show that she could put her trust in the kindness of local people.
Ms di Marineo was hitch-hiking from Milan to Israel and the Palestinian Territories with a fellow artist on their "Brides on Tour" project.
They had separated in Istanbul, planning to reunite in Beirut.
