Who Killed Pasolini?

Synopsis

November 2, 1975: Pier Paolo Pasolini is murdered in the outskirts of Rome. The suspect, a 17-year-old hustler, pleads to have acted in self-defense, citing Pasolini's notorious sexual habits as proof. However, many inconsistencies start to undermine his version, pointing to him not having acted alone or even being assaulted in the first place. Was Pasolini also killed for another reason?
