In director Jonathan Lynn's 1985 comedy film CLUE, who is the actual killer / are the actual killers?

Question

The film CLUE stars Tim Curry, Christopher Lloyd, and a cast of others. There are 3 different alternate endings. This murder mystery is getting me confused.
Here are my concerns:
Who really shot Mr. Body?
Who really stabbed the cook?
Who really struck the motorist with the wrench?
Who really strangled Yvette the maid?
Who really struck the cop with the lead pipe?
Who really shot the singing telegram girl?
This is all getting me confused. Some say Ms. Scarlett strangled Yvette, some say Mrs. White strangled Yvette, and this is making it unclear who the real murderer / murderers are. Post a response and tell me what you know. Simple answers will not be rated.

Answer 1

The last ending was the correct one, where everyone killed someone.

From Wikipedia:
No one person orchestrated all six murders. Each of the guests murdered one of the victims; Professor Plum killed Mr. Boddy, Mrs. Peacock killed the cook, Colonel Mustard killed the motorist, Mrs. White killed Yvette and Ms. Scarlet killed the cop. By process of elimination the guests accuse Mr. Green of killing the singing telegram girl, although he claims he is innocent. Wadsworth pulls the revolver from his coat, revealing that it was he who shot the girl, and holds the guests at gunpoint. Wadsworth then reveals the shocking secret that he is, in fact, the real Mr. Boddy. The "Mr. Boddy" killed earlier was actually his butler, set up to take the fall.

Mr. Boddy/Wadsworth thanks the guests for getting rid of his spies, and in doing so, all the evidence against him. He suggests they stash the bodies in the cellar, leave quietly one at a time, and pretend the evening never happened. He also plans to continue blackmailing them. Mr. Green suddenly shoots and kills Mr. Boddy, revealing that he is an undercover FBI agent. Backup forces rush in and surround the five murderers. The police chief asks which is the guilty party, and, in a nod to the game, Mr. Green replies, "They all did it. But if you want to know who killed Mr. Boddy, I did. In the hall, with the revolver."

Answer 2

First of all you have to realize that tim curry was the REAL mr body. the mr. body that came to dinner was his butler. Also the last ending on the movie is what REALLY happened
Thus-
Prof Plum shot Mr. body
Prof Green shot the telegram girl
Scarlet killed the cop
Mustard killed the motorist
peacock killed the cook
yvette killed the fake mr body (the butler)
mrs. white killed yvette

So now you know

Answer 3

If I remember correctly it was mr. wadsworth that commited all the deeds. Your right, it is difficult to recall, but i loved the movie anyway.
