THE PURPOSE OF THIS LECTURE l l l l IT IS FIREARM WOUNDS OR NOT ENTRY WOUNDS OR EXITS WOUNDS THE RANGE AND DIRECTION OF FIREWOUNDS YOU EXPECTED TO SAY WHETHER A GIVEN WEAPON COULD HAVE THE CAUSE OF THE WOUNDS HE FOUND YOU MUST KNOW SOMETHING OF THE COMMON TYPES OF FIREARM AND BE ROUGHLY FAMILIAR WITH THEIR MECHANISM AND FIRE POWER COULD IT HAVE BEEN SUICIDE, ACCIDENT, MURDER. CHARACTERISTIC FEATURES OF SUICIDES

WHAT IS FIRE ARM WOUNDS LOSS OF CONTINUITY OF TISSUE BY THE BULLET OF FIRE ARM OR EXPLOSIONS

The doctor must know something of the common types of firearm and be roughly familiar with their mechanism and fire-power

The study of firearms and ammunition – ballistics is sufficiently complex

TYPES OF FIREARMS l l l RIFLED SMOOTHBORED WEAPONS RIFLED WEAPONS BARRELLED SHORT- BARRELLED LONG - BARRELLED CALIBRE OR GAUGE INTERNAL DIMENSION OF THE BARREL BRITAIN ( IN DECIMALS OF AN INCH. 22, . 303, . 45) METRIC SYSTEM (6. 35, 8, 0, 9. 3 MM)

RIM BOTTLE NECK CYLINDER LONG BARRELLED

REVOLVER SHORT BARRELED AUTOMATIC

RIFLED WEAPONS l l l THE BORE IS SCORED INTERNALLY WITH A NUMBER OF SPIRAL GROOVES WHICH RUN PARALLEL TO EACH OTHER, BUT TWISTED SPIRALLY FROM BREECH TO MUZZLE THE PROJECTING RIDGES BETWEEN GROOVES ARE CALLED LANDS MAY BE EITHER LONG-BARRELED (RIFLES) OR SHORT-BARRELED (PISTOLS)

SMOOTH-BORED WEAPONS THE BORE OR INSIDE OF THE BARREL IS PERPECTLY SMOOTH FROM END TO END. l THE DIAMETER OF THE BORE MAY BECOME NARROWER OR CHOCKED TOWARDS THE MUZZLE. l

CARTRIDGES l l Made of brass or brass base and plastic tube. Consist of a cartridge case with a central firing cap at the base. The base of the cartridge project as a rim, to ensure that it does not moved forward barrel. The cap contains small amount priming powder ignited by the heat generated by sudden blow of the trigger hummer.

SUICIDE ACCIDENT MURDER

SOME USEFUL RULES l l l WOMEN RARELY SHOOT THEMSELVES SUICIDALLY “SHOT WOMAN IS A MURDERED WOMAN” THERE ARE DEFINITE SITES OF PREDILECTION IN SUICIDAL SHOOTING IT IS VERY RARE A SUICIDE TO SHOOT HIMSELF THROUGH THE ABDOMEN, EYE AND INACESSIBLE SITES SUCH US THE BACK OF THE HEAD, NECK OR BACK OF THE TRUNK THE RANGE IS IMPORTANT, AS BEYOND ARM’S REACH OF THE TRIGGER SUICIDES ARE ABLE TO FIRE REPEATED SHOTS INTO THEMSELVES EVEN THOUGH PATHOLOGICALLY EACH ONE TO APPEARS TO BE RAPIDLY FATAL.

SUICIDE ACCIDENT MURDER

SUICIDE FIREARMS WOUND l l l ALMOST ALWAYS CONTACT OR VIRTUALLY CONTACT CERTAIN CLASSIC SITES OF ELECTION: THE RIGHT TEMPLE OR LEFT INLEFT HANDED PERSONS CENTRE BROW THE ROOF OF THE MOUTH OVER THE HEART THE GUN MUST BE ARM’S REACH EASY TO REACH NOT THE BACK OF THE BODY, OR THE LEG THE FACE
