Answer:
Macbeth claimed that he had found the guards covered in the blood of King Duncan.
Step-by-step explanation:
He further used this to explain how the sight drove him to a point of extreme grief and being so distraught he was overcome with the need to avenge the murder of his King. Using this false story, Macbeth was successful in diverting any suspicion from him without the need of potential suspects -meaning there would be no one to argue or prove their innocence if whoever was blamed for it was no longer living.
Hope this helps!
