Conveniently, he cannot stand trial in France, which has also called for his arrest based on their own investigations, because he chose to become an international fugitive in Lebanon [1].
That said, I believe there has been prosecutorial interest around Anthony Ghosn--Carlos's son living in, to my last recollection, California--due to payments he made to the Taylors [2]. (The daughter, Maya, who is profiled in the article helping him escape is also in California, though there is no interest in charging her to my knowledge.)
