GRAZE WOUNDS WERE MADE BY HANDGUNS ON THE HEAD AND ABDOMEN OF WHITE SWINE. WOUNDS WERE THEN EXAMINED VISUALLY AND MICROSCOPICALLY. IN ALL WOUNDS, ELONGATED TISSUE FRAGMENTS (SKIN TAGS) WERE PRODUCED CONNECTED TO THE WOUND'S MARGIN BUT PROJECTING INTO THE CENTER. EXAMPLES OF WOUNDS FROM .22 AND .38 CALIBER GUNS SHOW SKIN TAGS POINTING IN THE DIRECTION OF FIRE. FURTHER, UNDER THE MICROSCOPE, THE SKIN TAG NEAREST THE WEAPON APPEARS AS A LACERATION WITH IRREGULAR MARGINS AND TISSUE BRIDGED BY NERVES, VESSELS, AND SKIN STRANDS, WHILE THE SKIN TAG BORDER FARTHEST FROM THE WEAPON HAS A SIMPLE, ABRADED EDGE. IT IS MISLEADING TO SIMPLY STATE, AS SOME AUTHORITIES HAVE, THAT SKIN TAGS IN GRAZE WOUNDS POINT IN THE DIRECTION OF THE WEAPON, OR OPPOSITE THE BULLET'S PATH, SINCE SKIN TAGS CAN BE EASILY REORIENTED. HOWEVER, THE DIRECTION OF FIRE CAN BE DEPENDABLY DETERMINED IN A GRAZE WOUND BY EXAMINING SKIN TAGS BY HAND LENS OR DISSECTING SCOPE FOR THE LACERATED BORDER, WHICH IS EXPERIMENTALLY SHOWN TO BE TOWARD THE WEAPON. EXAMPLES OF ACTUAL GUNSHOT WOUNDS IN WHICH THE DIRECTION OF THE WEAPON WAS KNOWN BY A BYSTANDER SUPPORT THIS CONCLUSION. BULLET RESIDUE PATTERNS OR POWDER STIPPLING MAY BE USED IN SOME CASES TO CONFIRM THE DIRECTION OF FIRE. ILLUSTRATIONS AND FOOTNOTES ARE INCLUDED. (PAP)
