Rosencrance and Gildenstern
Nobody, unless you count the voice that said that Macbeth had murdered sleep. He did kill the two grooms, but not until the next morning.
Macbeth figured that if the grooms were allowed to speak, they would deny any involvement in the murder of Duncan, and this would cause people to look elsewhere for his murderer. As it is, nobody (except Macduff) seriously doubts that the grooms were the killers.
He carries the daggers he has used away from Duncan's room. His wife wants him to return and plant them on the grooms, but Macbeth refuses.
Lady Macbeth made the plan. The grooms who were to be guarding the king were to be made so drunk that they would not wake. Macbeth was to go into Duncan's rooms, steal the guards' daggers, kill Duncan with them, wipe the blood on the grooms so they would look guilty and leave the daggers there, and return to Lady Macbeth after which they were to return to bed.
Macbeth [c. 1014-August 15, 1057] and his Lady [b. c. 1015] planned to blame the two royal guards for the untimely death of King Duncan I [d. August 14, 1040] of Scotland. Lady Macbeth was supposed to serve the guards drugged drinks, to keep them from protecting their sovereign. Macbeth was supposed to kill the sleeping, unarmed King and then the passed out, defenseless guards. The bloodied murder weapons were supposed to be left at the crime scene with the bloodied corpses. The crime scene was supposed to tell a tale of a king killed by his drunken guards and avenged by his outraged host. And that was what happened and how the royal guest chamber was made to look, in Act 2 Scene 2 of the Shakespearean play.

Lady Macbeth returns the bloody daggers (two of them) to the grooms in Duncan's chamber. Macbeth cannot face doing it.
Loads of people, including Macdonweald, Duncan, his grooms, Banquo, young Siward, Macbeth, Macduff's children etc.
Do you mean, "Who was accused of murdering Duncan"? The grooms in Duncan's chamber, for a start. Then Malcolm and Donalbain were accused of paying the grooms to commit the murder.
Lady Macbeth's reaction to Macbeth's confession that he had killed the grooms is one of shock and concern. She realizes that their plan to frame the grooms for King Duncan's murder has been disrupted and that their actions are beginning to spiral out of control. Lady Macbeth tries to maintain a sense of calm and composure while internally grappling with the consequences of their actions.
