1.Post In Discussion Board in the area topics from Week 2 after viewing the video clip �General�s Daughter�. As first officer on the scene how would protect the immediate and outer scene. (you find the body while on patrol). you will watch this video clip on you tube and then answer the above question, second question is, this is a scenario
As a police officer you are required to investigate crime, see Canlii as one of the duties of a police officer.
You have just investigated a break and enter into a house were the suspect smashed a rear window to gain access into the house. You find blood on the glass indicating the suspect has cut himself and the premise has been ransanked which could mean fingerprints have been left behind by the suspect. A television has been stolen. On leaving the scene, two blocks away, you observe a male carrying a television which matches the description of the one stolen from the crime scene. You stop and question the male. You observe cuts on his hands. The television�s serial number matches the one stolen.
You place the accused under arrest (notice the status change). Under common law you may search for identification and evidence. In this case you find a pry bar in the accused�s possession. You could seize the pry bar as evidence. What if you did not have reasonable grounds to arrest the male? What could you do?
Check It Out
Read and be familiar with Criminal Code of Canada section #489
What about the fingerprints at the scene? Read and be familiar with The Identification of Criminals Act
what you would do if you did not arrest the male in the above scenario and what could you do about the fingerprints left at the scene.
The third question is, In this lesson we will discuss the value of evidence and the proper techniques in collecting trace evidence.
�Understanding evidence continuity.
�Preparing evidence labels.
�Collecting and packaging blood, hair and fibers, semen, saliva, cigarette butts, paint, gases, and fingerprint evidence.
Please view the video clip taken from �Exhibit A� the link is found below. How Do you think this crime scene was protected? What evidence was collected and would that the evidence contribute to the solving of the case?
Evidence Manual
There are two important considerations in evidence collection:
1.Proper packaging of the evidence to maximize integrity.
2.Ensuring evidence continuity.
Evidence continuity is defined as �unbroken succession�.
For example if you were to collect the underwear as seen in Exhibit A and keep them in your possession until court, it would be unbroken succession of that piece of evidence or excellent evidence continuity. However in most cases evidence has to be passed on to other persons, experts for further examination.
This is where problems occur as evidence does get lost or tampered with. The original piece of evidence should be the evidence introduced into court.
Best Evidence Rule
The original piece of evidence should be introduced or be present in court.
Some basic rules need to be followed.
1.Initial all evidence
2.Use evidence labels.
3.Use evidence seals.
A permanent marker can be used to initial any type of surfaces. If the piece of evidence is too small package the evidence and initial the container. Initial everything in order to later identify the item in court as it is the item that you located at the scene. Initial the object in a location which will not interfere with the evidence it may contain.
Evidence labels are used to explain what is inside the evidence package. An evidence label includes the time, date, what evidence is inside the package and who collected the evidence originally.
An evidence seal is a piece of tape with a serial number on it to distinguish it from other pieces of evidence. The seal is placed on the evidence package to ensure no one tampers with the evidence and that you can attest to that fact that is the evidence seal is intact.
Protect Your Self
It is important to wear latex gloves when handling evidence:
1.It ensures you do not transfer any trace evidence onto the item you are collecting, such as your fingerprints.
2.The gloves protect you from bodily fluids such as blood which may contain hepatitis �A� or AIDS.
Anything may be used to package evidence, a film container, paper bag or plastic bag.
A simple way to package evidence is to use a �fourfold�
Take a 8 x 10 sheet of 1st fold it in half, place the evidence inside the fold, 2nd fold the left third of the sheet to the centre, then 3rd fold the right to the
centre and last a 4th fold across the top. Place the fourfold into an envelope and label the envelope and place an evidence seal on the envelope.

Please read the text in relationship to collecting and packaging of blood, hair and fibers, semen, saliva, cigarette butts, paint, gases and soil.
A word about fingerprints, fingerprints are very fragile. Latent (invisible) fingerprints can be rubbed off an object easily.
Collecting Objects For Fingerprint Examination
1. Hard surface objects such as beer bottles or pop can should not be packaged. Hand deliver the object to the expert without packaging. Handle the object in a
location were there it is unlikely to be fingerprints such as the lip of the beer bottle.
2. Soft surface objects such as paper should be packaged in an envelope
answer this question for the third one, 1.Describe how you would protect this crime scene
2.Describe what evidence was present and how might that evidence contribute to the solving of the case?
3.How would you collect and package any "two" peices of evidence
