CRIME:
The word crime is defined as an act punishable by law
Latin “Crimen.” meaning offence or charge
CRIME SCENE:
Defined as any place where an act has taken place that is contrary to the law
POLICE FORCE:
A police force is a constituted body of persons empowered by the state to enforce the law, protect property, and limit civil disorder. Their powers include the legitimized use of force; the term is most commonly associated with police services of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility.
DAY 1:
HISTORY OF POLICING
Modern police forces:
- The first organized police force was with king Louis XIV in 1667 to police the city of Paris
Purpose of Police force:
- ensuring the peace and quiet of the public and private individuals, purging the city of what may cause disturbances, procuring abundance, and having each and everyone live according to their station and duties
Modern police forces:
- City of Glasgow police (1800)
- Surete in paris (1810)
- Metropolitan police in London (1829)
- Royal Irish Constabulary (1822)
These forces were charged with a preventable Rolle patrolling the streets for the first time, maintaining a public presence. And investigating the crime as part of a professional service
Sir Robert Peel:
- 1809 - became a member of parliament
- Introduced the constabulary act in 1822
- 2 terms prime minister in Great Britain
- Municipal region of peel named after him
- Brought about metropolitan police act in 1829
- Popularized term “bobbies”
“The police are the public and the public are the police; the police being only members of the public who are paid to give full-time attention to duties which are incumbent on every citizen in the interests of community welfare and existence” -Robert Peel
POLICE FORCES: NORTH AMERICA
Benefits and duties:
- Keeping law and order, maintaining a ‘presence’
- Railroad security
- Labour strikes
- Horse thieving
- Rioting
Beginnings
- Began as a volunteer organization
- Recognized the need for more permanent authority
- Developed into a paid policeman position complete with formal training (gender specific)
When was the first municipal police force in North America: TORONTO
Watchmen in New York City in 16 hundreds, wasn’t recognized, ragtag
First signs of Canadian legal traditions in Quebec, 1651. Ontario was inspired and created its own after 1759
Expansion of police forces in NA:
- Toronto police
- Montreal and Boston police
- Quebec City police
- new York city police
- Philadelphia police
1834, the muddy town of “York” or “Muddy York” was renamed Toronto
The focus of police activity was on the business district of Yonge street
Following confederation, (1867), provincial police forces were established for rural areas In eastern Canada
HOW THE LEGAL PROFESSION HAS EVOLVED DURING THE CENTURY
The NWMP (northwest mounted police) pioneered the enforcement of federal law in the west, and the arctic, from 1873 until 1920.
It was amalgamated with the dominion police at that time to form the RCMP.
- In 2015 there were 176 stand-alone municipal police services serving 64% of the population of Canada.
- Provincial police services, limited to Newfoundland and Labrador, Quebec, and Ontario, policed 14% of the population of Canada.
- The RCMP provided municipal and provincial contact policing to 22% population of Canada in addition to its national and international programs
OPP:
- Provide rural policing needs for the province
- Provide urban policing needs where no there municipal/regional police service exists
- Provide support for all police agencies as required
Standards for policing services:
- The standards that police services must meet are set out in the police services act and regulations such as the adequacy and effectiveness of police services regulation
- The Ontario Ministry of community and correctional services provides the policing stands manual which contains guidelines to help municipalities and police services, understand and know how to follow the police services acts and regulations.
- Explains the minister’s position on policy issues
- Gives information and advice on how to manage and operate a police service
- Makes recommendations for local policies, procedures and programs
- Helps police services coordinate their activities
- Encourages community-oriented police services
- Promotes professional police practices, standards and training
Policing in Ontario
- Prevent crime
- Enforce our laws
- Help victims
- Keep public order
- Respond to emergencies
Two contradictory philosophies pertaining to the criminal mind dating back to the 1880s:
- Atavism: criminals were born to commit crimes due to biological deviance
- Positivism: crime was the product of social causes
PIONEERS IN FORENSICS
Cesare Lombroso (1839 - 1909)
- Advocate for Atavism, measured skeletons to determine criminals
Alexandre Lacassaagne (1843 - 1924)
- Advocate for positivism, professor of legal medicine, measured crime statistics in France and biographies of criminals to link crime rates with geography. “Father of forensic medicine”
BOTH methods were popular and formed the basis for gathering empirical data on crimes and the people who committed them
Alphonse Bertillon:
- Popularized headshots, and mugshots, taking physical aspects of a person to better narrow down suspects. Cataloging those and creating a database
- Criminal anthropologist - Anthropological techniques for identifying prisoners
- Realized a waste of time - criminals could change their names
- Created Bertillonage - anthropometry
- Took eleven measurements of head and body, including shapes of the ear, mouth and eye, limbs, scars, tattoos, and personal traits
Edmond Locard:
- Lacassagne’s assistant in Lyon, France
- Physician, but interest was with trace evidence, known as “dust”
- Early part of the 20th century studied all things contained in trace evidence
- Developed a methodology for examining causes of death ad any associated physical evidence
- Popularized the idea that, evidence is left when a crime is committed always. “When something is taken, something is left.”
- Every contact leaves a trace
- Established the exchange principle named after him.
- Established first crime lab in the world
Hans Gross:
- Austria professor of criminal law
- Wrote the book “Handbook for examining magistrates as a system in criminology” (in German)
- Popularized and created the term “criminalistics”
- Criminalistics became the term forensic science, the change occurring n the 1970s
- Integrating criminalistics into the justice system was the only way of riddling the legal system with “bias and misunderstanding”
DAY 2:
CRIME SCENE MANAGEMENT
Crime scene management
Are all “scenes” crime scenes?
Chief coroner for the province of Ontario: Death investigation of some sort
office of the fire marshal: A scene where a fire is involved
Ministry of labour: Something related to workplace crime or labour
Special investigations unit
So NO, not all scenes are crime scenes
Why do we need to manage crime scenes?
- Allow full investigation
- Proper documentation of evidence
- Collection of physical evidence
- Admissibility in court
Initial response/receipts of information: arriving at the scene; prioritization of efforts
- One of the most important aspects of securing the crime scene is to preserve the scene with minimal contamination and disturbance of physical evidence. The initial response to an incident shall be expeditious and methodical. Upon arrival, the officers shall assess the scene and treat the incident as a crime scene
- The initial responding officers shall promptly, yet cautiously, approach and enter crude scenes, remaining observant of any persons, vehicles, events, potential evidence, and environmental conditions
Safety procedures
- The safety and physical well-being of officers and other individuals, in and around the crime scene, are the intimate responding officer’s first priority.
- The initial responding officers arriving at the scene shall identify and control any dangerous situations or persons
Emergency care
- After controlling any dangerous situations or persons, the initial responding officers’ next responsibility is to ensure that medical attention is provided to injured persons while minimizing contamination of the scene.
- The initial responding officers shall ensure that medical attention is provided with minimal contamination of the scene
Secure and control persons at the scene
- Controlling, identifying and removing persons at the crime scene and limiting the number of persons who enter the crime scene and the movement of such persons is an important function of the initial responding officers in protecting the crime scene
- The initial responding officer shall identify persons at the crime scene and control their movement
Boundaries: identity, establish, protect and serve:
- Defining and controlling boundaries provide a means for protecting and securing crime scenes. The number of crime scenes and their boundaries is determined by their locations and the type of crime. Boundaries shall be established beyond the initial scope of the crime scene with the understanding that the boundaries can be reduced in size if necessary but cannot be easily expanded.
- The initial responding officers at the scene shall conduct an initial assessment to establish and control the crime scene and its boundaries
Documents actions and observations:
- All activities conducted and observations made at the crime scene, just one documented as soon as possible after the event to preserve information
- Documentation must be maintained as a permanent record
Conduct scene assessment
- Assessment of the scene but the investigators in charge allows for the determination of the type of incident to be investigated and the level of investigation to be conducted
- The investigators in charge shall identify specific responsibilities, share preliminary information, and develop investigative plans in accordance with departmental policy and local police.
Conduct scene, “Walkthrough” and initial documentation
- the scene walk-through provides an overview of the entire scene, identifies any threats to scene integrity, and ensures protection of physical evidence. Written and photographic documentation provide a permanent record
- The investigators in charge shall conduct a walk-through of the scene. The walkthrough shall be conducted with individuals
Determine team composition:
- Based on the type of incident and complexity of the scene, the investigators in charge shall determine team composition. Trained personnel shall perform scene processing
- The investigators in charge shall assess the scene to determine the specialized resources required.
Turn over control of the scene and brief the investigators in charge:
- Briefing the investigators taking charge assists in controlling the crime scene and helps establish further investigative responsibilities
- The initial responding officers at the scene shall provide a detailed crime scene briefing to the investigators in charge of the scene
Prioritize collection of evidence:
- Prioritize the collection of evidence to prevent loss, destruction, or contamination.
- The investigators shall ensure the effective collection, preservation, packaging and transport of evidence
L.O.S.E.R.
- Listen (listen to people or witnesses)
- Observe (observe broken or tampered with material, observe damage)
- Searching (searching for evidence, potential victims, suspects
- Evaluate (does it all add up?)
- Recording (record information through video, writing, whatever)
Primary (hot zone):
Greatest investigative interest and most often where events took place. Physical and trace evidence most likely compromised by non-forensic personnel
Secondary (warm zone):
Larger perimeter surrounding primary zone. Generally where line tape is located as a barrier to signify the crime scene perimeter
How do you maintain security?
Physical presence: police officers gauging the scene
Police line tape: barricading perimeter
Police evidence/security seals (tamper proof)
Locks and barriers: preventing public access, theft and unauthorized entry
Evidence logs
Securing and protecting: the scene security officer
Horrific scenes: problems with civilians, media and other police officers
“Keep your hands in your pockets”
Protect scene until forensic investigator arrives (exceptions: safety, destruction or degradation of evidence, public interest)
Path of contamination (route in, route out)
Give an accurate representation of the scene as FIS finds it
Changes prior to FIS arrival must be explained and justified
Articulation is key
How can we protect against change?
Scene security
Minimize contact
Follow LOSER principle
Be creative - be cognizant of how your efforts may protect or compromise evidence
Treat the same as any scene
Consider the path to the vehicle
Vehicle towed to a police garage for expert exam under seal
Vehicles must be dry before commencing the examination
May be held for hours, days, or weeks
Breakdown of scene determined by a case manager
Ensure proper cleanup
DAY 3:
CRIMINAL CODE OF CANADA
•A law that codifies most criminal offences and procedures in Canada. Officially known as "An Act respecting the criminal law"
•Section 91(27) of the Constitution Act - 1867, establishes the sole jurisdiction of Parliament over criminal law in Canada
•Criminal Code contains some defences, but most are part of the common law rather than statute.
•Criminal Code of Canada was first enacted by Parliament in 1892.
•One of the conveniences of the Criminal Code was that it constituted the principle that no person would be able to be convicted of a crime unless otherwise specifically outlined and stated in a statute. This legal document has played a major part in Canada's history and has also helped form other legal acts and laws, for example, the Controlled Drugs and Substances Act
What's the difference between an indictable and a summary conviction offence in Canadian law?
Under the Criminal Code of Canada, there are three types of offences: summary conviction offences, indictable offences, and those offences where the Crown may elect to proceed by summary conviction or by indictment. Crown-electable offences are often referred to as
"hybrid offences". The simplest explanation of the difference between summary conviction offences and indictable offences is that the former is less serious than the latter.
Summary Conviction Offences:
Less serious
Few are pure summary
6-month limitation for a charge
No fingerprints required
Generally maximum of 6 months of jail time
Indictable Offences:
- More serious
- Often life imprisonment is the maximum sentence Usually have the right of election (judge, judge and jury)
- No limitation for a charge
Hybrid Offences (dual procedure):
Crown has the option to proceed via indictment or summarily
ROLE OF FIRST RESPONDER
- Safety and physical well-being of officers and others at or near the scene are the responsibility of the initial officer and should be first priority
- First officers identify and initiate the appropriate response to dangerous situations or persons
- Once deemed safe, the next priority…
- Preservation of Life - Even at expense of damaging, degrading or destroying evidence
- Preservation of evidence and crime scene examination practices remain secondary considerations
- Even by first responders as training varies and scene priorities
- No problem changing scene (well can be mitigated) - but relay information to forensic personnel
- The duties of emergency first responders vary in complexity and are continuously evolving
- Government policies, societal demands
- Commonly three-tiered response
- Must act in sync with one another
- All incidents may have a criminal origin and must be taken seriously in this regard: can be downgraded as necessary and with more information being made available
Scenes will change - why and how?
Procedures to consider:
- Respond promptly, while exercising caution
- Remain observant - of surroundings
- Note dispatcher information
- Note persons and vehicles
- Cognizant of possible secondary scenes
- Initial observations (look, listen and smell)
- Ensure safety (officer/victim etc.)
- Ensure no immediate threats and mitigate
- Remain alert - assume crime is still in progress until determined otherwise
- Treat the scene as a crime scene unless determined otherwise
- Scan area (sights, sounds or smells) indicating danger - for CBRNE calls notify appropriate authorities
- Approach cautiously - in a way that will reduce risk while maximizing safety "no blue canaries"
- Survey for dangerous persons and take control of the situation
- Notify and update supervisory or investigative personnel and call for assistance or backup as required
Securing the scene:
- Determine parameters if possible and secure - limitations?
- Oversize if necessary
- One opportunity to do it right
Fall out?
Primary/secondary zones
- Primary (Hot Zone) - greatest investigative interest and most often where the event took place. Physical and trace evidence most likely compromised by non-forensic personnel
- Secondary (Warm Zone) - larger perimeter surrounding primary zone. Generally where line tape is located as a barrier to signify the crime scene perimeter
FORMS OF EVIDENCE
evidence defined:
The term evidence refers to anything that can give or substantiate the information in a legal investigation. Derived from the Latin "evidentia" (to be visible)
Therefore, the evidence must be visible to be acceptable and provide information that may prove or disprove a point in question
Testimonial evidence:
Witnesses who testify, provide knowledge or information concerning the case.
Testimonial evidence can be direct or indirect.
- Indirect: beyond the scene, did not witness the crime. Examples?
- Direct: witnessed the crime or are the victim of a crime.
Physical evidence:
Evidence that can be seen, touched, extracted and exhibited constitutes physical evidence.
Can be manufactured or found in nature.
Class: evidence that requires classification into a more narrow range.
Latent: any evidence that is not visible without the use of chemical, photographic or electronic development/enhancement.
Trace: evidence that has to be extracted from another substance and is in very small amounts, often invisible to the naked eye.
Circumstantial: facts, observations, or activities from which the culpability of an individual may be inferred.
Direct evidence is evidence that, if believed, proves a fact or resolves a matter in issue. The only inference involved in direct evidence is that the testimony is true.
Circumstantial evidence on the other hand finds its probative value in the inferences to be drawn from the facts. In other words, circumstantial evidence, if believed, allows a fact to be inferred. However, a jury must be cautioned about "jumping to conclusions" or
"filling in the blanks" with circumstantial evidence.
Distinguish between inference and speculation:
•Traditionally, inferences had to be taken from direct evidence of facts.
•The Supreme Court of Canada ruled that it is acceptable to pull inferences from circumstanial evidence.
- The inference is something that is reasonable.
- Speculation can lead to erroneous, flawed and faulty inferences.
The Supreme Court of Canada indicated that when it comes to circumstantial evidence, any inferences based on circumstantial evidence must be reasonable, and not speculative. The danger is that speculative inferences can cause a trier of fact to make a leap of logic, unsupported by the evidence.
——————————————
Physical evidence shows
- That a crime has been committed
- Key elements of the crime
- Link suspects with scene and/or victim
- Corroborate statements
- Exonerate the Innocent
Physical evidence:
- Fingerprints
- Footwear
- Firearms, other weapons
- Tool mark impressions
- Trace evidence: Blood, hair and fibres
Conducting scene assessment
Scene assessment allows for the development of a plan for the coordinated identification, collection, and preservation of physical* evidence and identification of witnesses. It also allows for the exchange of information among law enforcement personnel and the development of investigative strategies.
Conducting a scene walk-through and initial documentation:
Conducting a scene walk-through provides the investigator(s) in charge with an overview of the entire scene. The walk-through provides the first opportunity to identify valuable and/or fragile evidence and determine initial investigative procedures, providing for a systematic examination and documentation of the scene.
Written and photographic documentation records the condition of the scene as first observed, providing a permanent record.
Processing the crime scene:
- Assess the need for additional personnel. Be aware of the need for additional personnel in cases of multiple scenes, multiple victims, numerous witnesses, or other circumstances.
- Assess forensic needs and call forensic specialists to the scene for the expertise and/or equipment.
- Ensure that scene security and the entry/exit documentation are continued.
- Select qualified person(s) to perform specialized tasks (e.g., photography, sketching, latent prints, evidence collection).
- Document team members and assignments.
The scene(s) assessment determines the number of personnel and how responsibilities will be assigned.
DOCUMENTATION
The investigator(s) in charge and team members shall determine the order in which evidence is collected.
The team member(s) should:
Recording transient evidence and conditions
Documenting circumstances that require departures from usual procedures.
Review assessment of the scene to determine the type of documentation needed.
Coordinate photographs, video, sketches, measurements, and notes.
Photograph:
- Scene utilizing overall, medium, and close-up coverage.
- Evidence to be collected
- Victims, suspects, witnesses, crowd, and vehicles.
Additional perspectives (e.g., aerial photographs, witness' view, area underbody once the body is removed).
Videotape as an optional supplement to photos.
Prepare preliminary sketch(es) and measure:
- The immediate area of the scene, noting case identifiers and indicating north on the sketch.
- Relative location of items of evidence and correlate evidence items with evidence records.
The evidence prior to movement.
Rooms, furniture, or other objects.
Distance to adjacent buildings or other landmarks.
Generate notes at the scene:
- Documenting the location of the scene, time of arrival, and time of departure.
- Describing the scene as it appears.
- A well-documented scene ensures the integrity of the investigation and provides a permanent record for later evaluation.

Who can call?
The investigating coroner on call is notified and speaks with the reporting person to decide:
Is this a coroner's case?
If yes, the coroner will attend the scene of the death, examine the environment, examine the body, and interview family members or other relevant parties
The coroner will work with:
The police
Forensic Identification Services*
Criminal Investigation Bureau*
