Oh, and get this--he entered the European Union into Greece after departing Syria.
From the BBC:
The suspected ringleader of the Paris attacks, Abdelhamid Abaaoud, was among those killed in a French police raid on Wednesday, prosecutors say.
They confirmed the Islamic State (IS) militant had died in a flat in the Paris suburb of Saint Denis.
His body was found riddled with bullets and shrapnel in the apartment.
Interior Minister Bernard Cazeneuve said he had received intelligence that Abaaoud passed through Greece on his return from Syria.
