[White blood stains?]

Following to bullet wounds of the upper maxillary region and of the lungs great quantities of blood were expectorated by the victim soiling the clothes of the perpetrator. (These cloth consisted of a mixture of wool and synthetic fibers producing a rough surface.) The suit was washed out in cold water and dried. The only macroscopic findings were intensively stained white to grey spots missing any brown or red color portion. These were identified to consist of fibrin. Extensive examination proved the existence of blood spots of group A. Experimental stains applied to the same cloth showed identical changes after washing out.
