I'm looking for a black and white movie this is what I remember:
2 men and a woman find a gun playfully one of the men is shot in the eye, its an accident, and they hide the body in a dumbwaiter, blood of the body drips on the floor and the woman sees it and asked the other man to remove the blood, when he comes the blood is gone, the cat licked up the blood, they don't know that, and she is becoming more hysterical..
