Stéphane Bourgoin

Stéphane Bourgoin (born 14 March 1953), also known as Etienne Jallieu, is a French author specializing in true crime.

Between 1990 and 2020, he presented himself as an expert in offender profiling and criminology and was considered as such by the French media. In 2020, after various sources revealed improbability in his biography, he was forced to admit that he lied about several elements of his past that credited his purported expertise.
