Who is the murderer of shining?

The "Shining" is a novel by Stephen King and was later adapted into a film by Stanley Kubrick. There are two possible interpretations of your question:

* If you're asking about the murderer in the *book* "The Shining": Jack Torrance is the murderer. He kills his wife, Wendy, and attempts to kill his son, Danny.

* If you're asking about the murderer in the *film* "The Shining": Jack Torrance is again the murderer, but the film's portrayal is more ambiguous. While he tries to kill his son, his fate in the film is unclear.

Both the novel and film feature a complex exploration of themes like madness, family dynamics, and the dangers of isolation. The question of whether Jack was truly responsible for his actions or if he was influenced by the Overlook Hotel is left open to interpretation.
