Unit 1: Drug Evidence
The illegal drug trade has been a major concern within North America for law enforcement and the criminal justice system. It is not surprising, then, that this area also presents a major area for forensic science. Forensic scientists play an important role in investigating and solving drug cases. Not only do they help to identify whether illegal drugs are present at a crime scene, but they also help identify the particular drugs and how they may have been involved in different crimes.
What will you learn in this unit?
- Learn about some of the different types of drugs and their effects.
- Examine some of the common ways that samples can be taken from humans to test for drugs.
- Consider some of the issues in collecting and preserving drug evidence.
- Investigate screening tests and their uses in criminal investigations.
- Discuss confirmatory tests and their uses in criminal investigations.
Unit 2: Forgeries and Document Examination
During crime investigations, forensic scientists may be called upon to determine whether a paper, signature, or other created document is authentic or whether it is fake. In this unit, we will examine the area of document examination. Document examination may include comparing the handwriting of several samples, linking documents to the particular machines that created them, and identifying counterfeit papers and money. We will discuss some of the aspects that document examiners look for in comparing documents and some of the techniques they use to find alterations in documents.
What will you learn in this unit?
- Learn about questioned documents and exemplars.
- Examine some of the aspects that document examiners use to compare handwriting.
- Investigate some of the aspects that document examiners use to compare typescript.
- Discuss some of the ways that document alterations can be found.
- Learn more about how document examiners find forgeries and counterfeit materials.
Unit 3: Forensic Toxicology
Arsenic, cyanide, and strychnine have all been used to try to harm other individuals throughout the course of history. Although poisoning may not be the most common way of trying to kill someone, it does happen, and forensic scientists play an important role in determining what has occurred. In this unit, we will explore some of the poisonous substances that exist and how forensic scientists test for and identify poisons.
What will you learn in this unit?
- Learn what poisonous substances have been used in history.
- Understand how poisons are absorbed and transmitted through the body.
- Discuss techniques used by forensic scientists to identify poisons and other toxins.
- Examine the collection and preservation of blood evidence.
- Consider the role of toxicologists in criminal investigations.
Unit 4: Paint, Soil, & Trace Evidence
Trace evidence left at a crime scene can yield important clues about the victim, perpetrator, and the crime scene. In this unit, we will examine some of the trace forms of evidence that forensic scientists may use to help them solve crimes. These may include paint chips, pieces of metal, soil, and so on. In doing so, we will examine some of the techniques that forensic scientists use to identify and compare these pieces of evidence.
What will you learn in this unit?
- Learn how protons, neutrons, electrons, and other aspects are used by forensic scientists to study trace evidence.
- Learn about the nature of matter and its relationship to elements and compounds.
- Consider the usefulness of various forms of trace evidence in investigating crimes.
- Learn about different types of microscopes and how they work.
- Examine some of the tests used to identify and compare trace evidence.
Unit 5: Forensic Entomology
In some criminal investigations, forensic scientists examine insects and other arthropods. In this unit, we will explore the area of forensic entomology and its use in criminal investigations. We will learn about the history of forensic entomology and the types of insects commonly encountered in crime investigations. We will also examine some of the tests and techniques used to study the insects.
What will you learn in this unit?
- Define forensic entomology and its uses.
- Learn about the history of forensic entomology.
- Examine what insects and arthropods are common pieces of evidence in criminal investigations.
- Investigate some of the tests used in forensic entomology.
- Learn about studies into insect activity as they related to forensic science.
Unit 6: Forensic Anthropology
Bodies, bones, and teeth can provide investigators with important information about how someone died. In this unit, we will explore the areas of forensic anthropology and facial reconstruction. We will consider some of the aspects that forensic scientists look for when examining bodies and skeletons.
What will you learn in this unit?
- Learn about the areas of forensic anthropology and forensic odontology.
- Discuss the history of forensic anthropology and odontology.
- Consider some of the characteristics of bones and teeth that provide forensic scientists with information about the person.
- Examine some of the tests used in the area of forensic anthropology.
- Investigate the use of forensic anthropology in the criminal justice system.
Unit 7: Digital Evidence
Computers are increasingly playing an important role not only in our daily lives, but also in the area of criminal investigation. In this unit, we will learn about the evidence that can be gained from computers and other electronic devices. We will consider how information can be retrieved from computers and how computer evidence should be preserved.
What will you learn in this unit?
- Understand the different parts of computers.
- Discuss the areas of a computer where information can be retrieved.
- Examine how internet activity can be traced.
- Investigate how emails and other aspects can be traced and examined.
- Consider how computer evidence can be collected and preserved.
Unit 8: The Future of Forensic Science
As technology has changed and advanced so too has the area of forensic science. In this unit, we will consider how computers are being used in forensic investigations. We will look at how forensic scientists retrieve web-based information as evidence and investigate the problem of hacking. We will learn more about some of the databases that forensic scientists use in their work. We will also examine what the future of forensic science may hold and how crime investigation is likely to change.
What will you learn in this unit?
- Consider how computers are being used in forensic science.
- Discuss some of the recent advances in forensic techniques and testing.
- Learn about how advances in other disciplines impact forensic science.
- Examine some of current limitations of forensic science investigations.
- Investigate some of the possible future changes in forensic science.
