On joining the cadets in 1959 after five years at high school, never in my wildest dreams did I think I would become a ballistic expert. In fact I had never even fired an air rifle let alone a rifle before then.
When I was transferred to the then Technical Section in March 1960 to replace Cadet Frank Wagner who became a probationary, did I even know anything about what was to lay ahead of me. My boss DSS Les Bardwell outlined what my future would hold if I wanted to pursue it.
First I had to attended The Central Technical College (now QUT) to study for a Diploma in Industrial Chemistry a five year course then I would work my way towards becoming a forensic scientist, a ballistic expert and also a handwriting expert, the first two appealed to me but being a handwriting expert left me a bit cold.
Les Bardwell then gave me three books to read, one by Kirk on criminalistics (an early name for forensic science), one by Hatcher on ballistics and a third by Osbourne on handwriting. The first two books were read with much enthusiasm, the handwriting book I put to one side and never read it.
How does one become a ballistic expert? Three years of intense study, working beside my boss. Learning about firearms, attending shooting related crime scenes, firing the many different types of firearms and working with the comparison microscope to compare rifling marks on fired projectiles and discharged cartridge cases.
I visited the Lithgow Small Arms Factory for two weeks to study the manufacture of the semi automatic 7.62cal SLR rifle which had taken over from the .303cal SMLE bolt action rifle. I test fired 10 consecutive rifles taken off the production line and examined the cartridge cases and projectiles which showed that no two rifles produce the same rifling marks.
I also visited the NSW Ballistics Section to work with their staff. This section was recognised as being leading section in Australian. In every other state the ballistic sections were stand alone in Qld we were also forensic scientists. Now in Qld, ballistic experts have their own section.
It is important to become involved with the firearms community. Getting to know local firearm dealers and gunsmiths. I also joined the Police Pistol Club and a shotgun club. Hunting with firearms was not in my DNA.
My first major shooting murder investigation occurred when my boss was on holidays, in the first week after being sworn in. I attended a shooting at Marburg where a 12 year old boy shot his father in the head with a .303cal rifle as he slept. His reason being his mother and he were the victims of DV.
I learnt that examining a crime scene with competence and confidence and consulting with investigators to ensure that they are happy with what you have done is the key to success.
Part 2 outlines the work of the ballistic expert.
Ballistics is a fascinating world with so many questions to a answer:-
1. Did the exhibit rifle fire the exhibit projectile and discharged cartridge?
2. From what range was the firearm/shotgun discharged?
3. How safe was the rifle?
4. Had the suspect recently discharged a firearm?
5. Was it murder or suicide?
6. Was it murder or an accident?
7. Identification of the the make of firearm that discharged the exhibit projectile and discharged cartridge case.
8. What size shot was fired in a shotgun and identification of brand of cartridge from wadding found at scene.
9. How recently had the firearm been discharged?
10. Determination as to whether a weapon was a concealable firearm.
11. Preparation of statements and giving evidence in court as an expert witness.
In my 35 years at Scientific Section I gave sworn expert evidence on over 1,000 occasions not including hand up briefs or guilty pleads, 500 of these appearance where in relation to ballistic evidence. I always kept records of my court appearance together with defendant's name.
Cross examination was varied and often centred around the possibility of a weapon to accidentally discharge and with crimes involving larger calibre firearms and shotguns the issue of recoil was frequently raised.
Other duties included:-
*Safety testing of imported firearms
*Teaching and supervising police recruits at the pistol range.
*Instructing members of the Police Emergency Squad.
*Lecturing police and recruits on ballistics.
Ballistics was a fascinating and challenging forensic discipline and I loved my involvement with it.
