THE FORENSIC
PERSPECTIVE…


   Melinda Matte
CASE HISTORY
Allegations included:
 Female walking home and confronted at
 knifepoint by male
 Abducted and brought to vacant townhouse
 Sexually assaulted vaginally with heavy
 bleeding, face licked
CASE HISTORY
 No shower prior to SAEK
 SAEK collected within ~10 hours
 No last previous intercourse – complainant
 a virgin
ITEMS COLLECTED
Underwear from suspect – Exam for blood
Sexual Assault Kit – Exam for blood/semen
   Underwear
   Skin swab - face
   Toxicology samples – blood & urine
   Buccal comparison sample
   Sanitary napkin
   External genitalia swab
   Vaginal samples
   Rectal samples
ITEMS COLLECTED
Swabs from scene – washing machine and
laundry sink – Exam for blood/semen
Cloths and rags from scene – Exam for
blood/semen
Clothing from scene – Exam for
blood/semen
DOES COLLECTED = EXAMINED ???
 Not necessarily!!
 Not all items that are collected from the
 suspect, at the scene or in the sexual assault
 kit are looked at
 Items are triaged based on the case history
 provided by police, nurse exam forms etc
 and questions being asked
HYPOTHESIS BASED TESTING
HYPOTHESIS BASED TESTING
 What questions need to be answered?
 What testing will assist in addressing the question
 at hand?
 A Forensic Scientist can only determine this from
 the information provided
 Our purpose is to determine whether an individual
 can be excluded as the source of a body fluid stain
 or other bodily substance, the source of which is
 in question
 We continue to test items until we have answered
 this question
TESTING
 Underwear from accused – Blood
 Face swab from complainant – DNA
 Swab from washing machine at scene –
 Blood/Semen/DNA
 Vaginal samples from complainant – Semen/DNA
 Comparison samples from accused and
 complainant - DNA
RESULTS
Accused underwear – No blood detected
Face swab from complainant – Only her
DNA
Swab from washing machine at scene –
Blood was detected, no semen was detected
via DNA, complainant could not be
excluded as source of DNA profile
RESULTS
Vaginal samples from complainant were a
challenge in DNA due to the heavy blood
staining – needed to use both vaginal
samples to obtain a DNA profile from
semen
DIFFERENTIAL EXTRACTION

RESULTS – DNA Comparison
The accused cannot be excluded, at up to 9 STR
loci, as the contributor of the male DNA profile
from semen on the vaginal samples from the
complainant.

The probability1 that a randomly selected individual unrelated to the
accused would coincidentally share the observed DNA profile is
estimated to be 1 in 2.2 billion.
CONCLUSIONS
           Some lessons learned
May not always get result on first sampling
   • i.e.needed to use 2nd vaginal swab
May have been more valuable to look at
underwear instead of 2nd vaginal swab
   To isolate a semen stain with less blood staining
   This is typically what is done now in sexual assault
  cases
 THE CROWN
PERSPECTIVE…


  Michal Sokolski
      Criminal Trial Route
Police take witness      Possibly a bail hearing
statements and collect   Possibly a preliminary
evidence                 hearing
If they have RPG and     Trial
have established         Conviction or acquittal
identity will arrest
                         Possible appeal
Evidence collected
will be used at trial    Disclosure throughout
                         process

           Types of Evidence
  911 calls
  Witness statements
  Clothing of victim (possibly of accused)
  Weapons used
  Photographs of victim (possibly of accused) and
  scene
  Medical evidence, DNA
Evidence collected must, in general, be disclosed.
          Factors re: Bail
Seriousness of offence
Does accused have criminal record
Risk to victim/public
Risk of accused interfering with
witnesses/evidence
Risk of accused running away
Availability of suitable surety
         2 Common Scenarios
“DATE RAPE”                “STRANGER RAPE”
  Id of A known              Id of A not known
  Defence may be ‘it         Defence might be it
  never happened’            never happened
  Or ‘he/she consented’      Rarely – consent
  Usually no extra           Usually extra violence
  violence (or injuries)     (physical injuries)
  DNA to confirm it          Injuries to show force
  happened                   DNA to prove it
           Mode of Trial
Summary = Provincial   Indictment = Superior
Less serious           More serious – need
                       more than 18 months
Sentence up to 18      jail
months (for most
                       Prelim (Prov. Ct.)
sexual offences)       Trial (Sup. Ct)
Only testify once      judge and jury or
Judge alone            judge alone (accused
                       chooses)
          Medical Evidence
Usually admitted at the preliminary hearing
without need to call authors of reports
If not admitted by defence then author must be
called to have it admitted
At trial, medical reports sometimes not admitted
by defence without calling the authors
Even if admitted, Crown may still call for greater
impact and clarity
May testify as an expert or a factual witness
              Witnesses
Testify about they heard, saw, injuries seen,
demeanour, physical evidence, processes
and procedures used to gather evidence
Can be civilian, police or experts
Medical witnesses can testify about areas of
expertise and/or observations,
interpretations and procedures
         Expert Witness
Testify about the interpretation of what they
have seen; such as whether injuries are fresh,
how injury may or may not have been caused
To testify about this must be qualified as an
expert by the court – usually, they would have
produced a CV that is provided to defence in
advance (which should include whether they
have been qualified as an expert by a court in
the past – not a bar if they have not)
Sometimes admitted by the defence
      What makes an Expert??
Four criteria to admit expert evidence
1. Relevance
2. Necessity in assisting the trier of fact
3. Absence of any exclusionary rule
4. Properly qualified expert (knowledge
   beyond what the ordinary person would
   have on that subject)
          What To Do….
If you receive a subpoena, call the OIC and
find out if you will be an expert or not
If an expert – might be entitled to expert
fees, should meet with the Crown in
advance, will need more preparation for
court, should provide a CV
Have to give 30 days notice of intention to
call an expert (with c.v. and report asap)
        What To Do Cont’d
ALWAYS REVIEW NOTES IN ADVANCE
Remember, it could be anywhere from 8 months
to 3 years after speaking to a victim that you might
be called to testify
You might have to testify twice (prelim + trial)
Advise oic of any change of address, phone no.
etc.,
    Why You Are Important
Medical evidence is very persuasive
It will corroborate the victim’s story
(hopefully!)
Evidence will have been gathered close in
time to the incident (hopefully!) – will take
the judge/jury back to that time
    Things to look out for….
Some cases hinge on DNA evidence so
avoid contamination
proper continuity of samples are vital to the
case
   Recording Your Evidence
Take detailed, legible notes
Note where the source of your information is
coming from
Be very particular about description of injuries
Photos, if possible
Give entire sex assault kit to police
Your notes (medical file) are discloseable – but
usually we do not give them unless the defence
asks for them
                Memory
Chances are you might not even remember the
case…so:
Routine is important – does not matter how you do
it, just make sure you do it the exact same way
each time – if deviate from the norm, make a note
of the difference
If there are standard processes and procedures,
know them and follow them
If defence suggests you don’t have a memory, can
say that you collect samples exactly same way and
if it was different, you would have noted it
               Continuity
For evidence to be made an exhibit with
evidentiary weight, Crown must establish
continuity
i.e. This item was the item that was seized and it
has not been altered
Chain of control – you are the first link
Crucial to note who you gave item to, how sealed,
date/time
Always seal, date, sign
Forensic Nurse VS. Counselor
Conversations between victims and
counselors have some degree of
confidentiality
As a nurse, you don’t have this; anything
victim tells you could be disclosed
Make victim aware of this
Do not ask personal questions unless
relevant to the exam
        Testifying in Court
Be Patient!!
Make sure you have your notes with you
Accused will be in the Court Room
Crown – open questions (can’t lead)
Defence – cross examination (to suggest does not
make it so) – Be Patient!!
Crown can re-examine
You will not have heard other witnesses
    Testifying in Court ctd.,
Judge may ask you questions directly
Don’t argue with defence counsel
Don’t take it personally
BE PATIENT!!
Warts and All approach – tell it all, do not
edit – let the Crown deal with any problem
areas
No surprises please!!!
    Testifying in Court ctd.,
If you are called to testify and asked a direct
question, you must answer truthfully and
not in a way to assist the victim
You must not appear biased
Only say, I don’t remember, if you don’t
remember
You will not know what the evidence was
before you or what it will be after you
    Testifying In Court ctd.,


BE PATIENT!!!!!!!!!!!!!!!!
           Role of Crown
Crown is NOT the victim’s lawyer
Crown’s job is to present the evidence
Crown should not proceed if there is no
reasonable prospect of conviction
It is not the Crown’s job to ‘get’ the accused
Crown must be fair and unbiased and ensure
the proper administration of justice
    Role Of Defence Counsel
Advocate for the Accused – to protect his/her
rights
Must do whatever is necessary (within limits) to
render a result of not guilty
They advise the client, but ultimately they must
take instructions from the client
Try to bring out the weaknesses in the Crown’s
case
Defences can change without consequence
            Defence cont’d
Depending on the strength of the case, may or may
not call witnesses (including the accused) – they
don’t have to prove anything
If A tells lawyer his version of events (and these
show guilt), lawyer cannot call A to testify and lie
about it – in this case, the A won’t testify but
lawyer does not have to advise Crown or court of
reason or of A statement
Whatever A tells his lawyer, is privileged
Whatever the V tells police/Crown/you is not
               The Judge
Is the trier of fact
He/she must decide whether Crown has
proved it’s case BEYOND A
REASONABLE DOUBT
Will apply the law
Will sentence the accused after conviction
Note: a jury is the trier of fact and the judge
helps the jury apply the law
          Domestic Issues
Sometimes these victims give you a reason
for the injuries that you do not believe – if
you take notes of this, must note what you
are told
Do not try to explain or justify her account
in your notes or on the stand…you are not
an expert psychiatrist
             Finally…
YOU MUST BE AN INDEPENDENT
WITNESS, NOT AN ADVOCATE FOR
THE VICTIM
The victim’s inconsistencies may be
explained; if is felt you are not being
forthright, it cannot
