BACKGROUND

 

I joined the Waterloo Regional Police in 1982 and began work in the Patrol Branch, working in Waterloo and in 1984 transferring to Cambridge.  I was trained in January of 1984, as an Emergency Response Officer.  In May of 1986, I was trained as a Dog Handler with the Canine Unit.  In February of 1991, I transferred to the Forensic Identification Branch and remained there until retirement after 21 years.

 

 

 

 

DUTIES PERFORMED WHILE EMPLOYED

 


FORENSIC IDENTIFICATION DUTIES

 

I received orientation training in the Forensic Identification Branch under the direction of a senior identification officer.  In May/June of 1991, I attended the Scenes-of-Crime Officer course at the Ontario Police College.  The course content consisted of :

 


- scenes of crime photography

- interpretation of fingerprint patterns

- examination of the crime scene for fingerprints

- examination of the crime scene for impressions of footwear, tools, vehicle tires and gloves

- collection and preservation of physical evidence including evidence for submission to the forensic lab

- take measurements of a crime scene, properly record the measurements and produce a flat plan drawing   

 

In November/December 1991, I attended the Ontario Police College for the accredited identification course, Forensic Identification.  The course content consisted of :

 

- comparison and identification of fingerprints

- comparison and identification of physical matches

- studio and laboratory photography

- scale plan drawing

- chemical development of fingerprints

- dye enhancement of developed fingerprint impressions

 

 

In January of 1996, I was trained in DNA sample collection by the Centre of Forensic Science and was certified to collect blood, buccal and hair DNA warrant samples as per the Criminal Code of Canada.

 

 

In May of 2000, I was trained in DNA Sample Collection and was certified to collect DNA samples ordered as per the DNA Identification Act.

 

 

FIREARM/SHOOTING INCIDENT ANALYSIS DUTIES

 

I have had a keen interest and have studied the science of firearms and ballistics for more than 40 years.  In February of 1999, I was trained by the R.C.M.P. as an Approved Verifier within the meaning of the Firearms Act.  This training involved the identification of firearms for the purpose of firearm registration.  I hold certificates as both an Individual and Police Verifier.  In March of 2000, I was trained as an Instructor/Examiner for the Canadian Firearms Safety Courses (both Restricted and Non-Restricted).  In May of 2001, I received training in Shooting Incident Reconstruction.  This involved ballistics, trajectory and angle of impact determinations, gunshot wound characteristics and firearm function testing.  In June of 2003 this training was expanded with an Advance Shooting Incident Reconstruction Course.  This included more, indepth study of the above, as well as bloodstain pattern analysis at shooting scenes.  In January 2008 I completed a Firearm Examiners Course with the Toronto Police Service that included Canadian firearms law, firearm tracing, firearm identification, test firing and submission of firearms and cartridge cases to the Centre of Forensic Science.  I have attended workshops on the topics of wound ballistics and gunshot residue collection.  I have presented firearm evidence in court and have been accepted as an expert witness in the Ontario Court of Justice and the Superior Court of Justice.

 

 


 

 

BLOODSTAIN ANALYSIS DUTIES

 

Bloodstain Pattern Analysis is the study of the size, shape and location of bloodstains, in order to provide an interpretation of the physical events which gave rise to their origin.

 

 


In October of 1999, I began the course of study to become an expert in the field of Bloodstain Pattern Analysis.  This began with the 40 hour Bloodstain Pattern Recognition Course and continued with the 40 hour Math, Physics and Bloodstain Pattern Analysis Course.  In May of 2003 I completed an Advanced Bloodstain Analysis course. In December of 2003 I completed a Bloodstain Understudy Program under the direction of the Ontario Police College and my mentor, Senior Constable Craig Stewart, Ontario Provincial Police.  On December 12, 2003 I successfully completed an oral board examination at the Ontario Police College and was designated as a qualified bloodstain pattern analyst.  I have attended numerous blood letting scenes and have written analysis reports of these.  I have presented bloodstain evidence in court and have been accepted as an expert witness.

I trained the first Bloodstain Pattern Analysts for both the Hamilton Police Service and Toronto Police Service (Ontario, Canada).

  

A Bloodstain Pattern Analyst is trained to :

 

                                - examine crime scenes and/or exhibits.

                                - provide information to investigators.

                                - provide expert testimony to the courts.

                                - satisfy questions.
