The caretaker killed this old man because of his evil eye that reminded him of a vulture's eye. Now the caretaker is trying to say that he is not insane.
Maybe I shouldn't have done that.
The caretaker is going to check on the old man to see if his eye is open. If it is he will finally kill the old man.
The caretaker drops his lantern and the old man wakes up frightened.
The caretaker waited for the right time to strike. When the old man wasn't expecting anything the care taker dragged him to the floor and pulled the heavy bed over him and waited till he heard no heartbeat.
Time to hide the evidence.
The caretaker now needs to hide the body pieces he cut up from the old man.
The cops came to investigate the noises that were reported from last night. The caretaker welcomed them and they talked for a while until the caretaker started to hear noises. The noises became louder until the the caretaker finally admitted the deed of killing the old man.
