The Netflix documentary, Son of Sam, exposes that a Satanic cult was involved with the Son of Sam killings. It shows that the law enforcement would not look at this connection once they got their guy. They even ignored evidence that pointed to these accomplices. However, this documentary goes deeper than this one case. It explores how the journalist who discovered this connection, later found that this cult was involved with other Satanic groups that were involved with other serial murders and events throughout the country. The documentary shows how his discoveries led him to write a book which got him famous, however many people in power refused to take him seriously and ignored him. It's an interesting documentary if one wants to watch it.
