This message is for you, my students, and anyone else reading this page. At the start of 2021, I offered a challenge to all my students, and who anyone else who was listening. The challenge was simple - perform a random act of kindness, of any kind, and then share the act on social media with me and the world. I think far too often, with the best of intentions, we all do kind things for others, but then stay quiet about it. It seems wrong to share or speak about it, as it feels like that takes away from the act. However, my challenge is to go against that thought, to know it is not being shared for self promotion, but rather to help make demonstrations of kindness more prevalent in our world. They often happen, but we don't see them, instead we see when the opposite occurs far too often. Now, as we come to the end of 2021, and a new school term begins, I wish to know how many would like to see the challenge continued? Last time, I offered to throw myself in a snow bank wearing nothing but a swimsuit, if the challenge was met. And, it was, in amazing ways, so into the snow bank I went on Feb 28, 2021 (and yes, it was cold - you can hear that at the end of the video - at the bottom of the page). So please, respond to this post, let me know if you'd like to see the kindness challenge? And, if you wish suggest what the stakes should be... do I throw myself into the snow again, do I build a larger snow bank and stay in it longer ... what do you think the stakes should be for accepting the challenge I offer you? I hope to hear from you, as the challenge is nothing, without you! If you wish to read more about the #KindnessChallenge, you can find it by clicking here: #KindnessChallenge

Welcome to Forensium, a forum to talk about Forensics, where you can ask about anything you want to learn, or share what you know. The idea here is simple: Forensics is a merging of disciplines, and any field of study may be forensic depending on the circumstances. So, the more a person appreciates how other fields of study may aid their investigations, the better their investigations will be. Here is where you may ask any questions relating to forensics, or where you may share your understanding, from experience or studies, to help others in their search for forensic knowledge. Please remember, forensics requires critical reasoning, and as such any investigator must maintain both an open and a critical perspective. Consequently, at times we may find ourselves in a disagreement, or in a situation where a challenge to certain ideas or concepts must be made, and this is essential. Above all else, in any discussion or question -- it is equally, if not more important to be respectful and kind -- and nothing to the contrary will be tolerated in this forum! In these positive interactions where we focus on both the task, which is the information we wish to learn or share, and the relationship -- respectful and kind interactions with another person -- we can expand our knowledge of what forensics can truly be and aid each other in our understandings.

Have you ever heard of Forensic Interviewing? It sounds almost ominous doesn't it! Many when they hear the words forensic interviewing, think it must be great, but don't really know what it is, or who does it. However, forensic interviewing is significant for investigations involving some of the most vulnerable members of our world - kids. It is important for investigators to understand what forensic interviewing is, and how it may look, if you involve it in your investigation or are supporting a victim through it. Now I am not an expert in this field, but have found and reviewed an amazing resource to point out, which was created by experts, and those who can help you learn more about it. This is only one are of forensic interviewing, so please do not take it as the only source you should explore. But this is a great place to begin!

For students, do you need help properly citing your sources, or having them in the correct format? Here are some amazing guides to proper referencing, which can be amazingly useful as you are creating your written submissions: Purdue University - a spectacular website that provides the most comprehensive citation guide, as well as a sample paper for students or academics to refer to! Definitely Check It Out! https://owl.purdue.edu/owl/research_and_citation/apa_style/apa_formatting_and_style_guide/general_format.html Aside from the previous, one of the only things that guide does not provide is how to cite legal references (e.g. statutes). There are a few different websites for this, but I would highly recommend the website provided by Douglas College Library, for legal citation. https://guides.douglascollege.ca/APA-7/LegalCitation Here is another offered by Durham College for APA 7th Edition and a link provided by Durham College for McGill 9th Ed - Legal Citation (which is the ultimate Canadian legal citation guide) If those don't work for you, please let me know. If you know of sources better, or equally as good as these, please let me know and I can add it to the list. Writing citations is at times one of the most challenging things for young students, and hopefully these can help get over that barrier! Take care, stay safe, and have a great day.

This message for all the students, or parents of students who are just trying to learn more about forensics. May I ask for you to please let me know what else you would like to see on the site? This website is a passion of mine, and one I do for free, as I enjoy helping others learn more about forensics. I will slowly update the content, and go into more depth in all the current categories. But if there is anything else you would like to see, or different types of resources you would like me to focus on sharing, please send a message here and let me know. I am happy to do whatever I can to help, and make this website work better for you to learn more about forensics. Take care, stay safe, and have a great day! - Scott Mark

We are often taught that fingerprints are permanent, persistent, and everyone has them. They are undeniably used for individualization, and one of the most fundamental disciplines in forensics. However, did you know that not everyone has them! This is often thought of as an urban myth, or part of some Hollywood crime drama, however, the truth is, not everyone has them. There are only a small number of families in the world, who are known to have a genetic mutation that results in the condition Adermatoglyphia. With this condition the friction ridges, which make up fingerprints, do not develop at all. Not on the tip of the fingers, not on the palms of the hands, and not on the soles of the feet. If this has caught your interest, here is an article worth reading that can be the beginning of your research on this unique condition! The family with no fingerprints

On the internet you often come across many sites, which seem interesting, but you are never sure about the reliability, or if the site is about the information or had other other motivations. As such, it is truly a gem when you find a site that offers great information for the purpose of just sharing what they know. Here is a great YouTube Channel -- I highly recommend -- if you are interested in Forensic Entomology. As it is that gem! Crimes and Forensic Team - You Tube Channel

In forensics, there is one main thing that many overlook, and that is the limitations it has. There is a saying that many add when they are skeptical: to take the information with a grain of salt. Now I always thought this had to do with something not being as sweet as it sounded, but the phrase actually stems from a much darker etiology. To very generally summarize (and please forgive me linguistic historians, as this may not be to the level of detail you prefer), salt was once thought to be a cure for some poisons, and so if you were to take a poison with some salt, you would not be adversely affected by it. Now the science behind this, isn't quite there, but the analogy fits. With each piece of information we take in, we must do so with a critical perspective of it, to prevent it from poisoning our minds or our reasoning. In forensics, everything must be taken with a grain of salt, including the critiques of it. On that note, here is a great article I recently read, which led to this post, and I think is one worth taking the time to reading.

Ever wonder, if you wanted to examine an item for fingerprints, what processes may be used, or what path to take? A long while ago (last revised in 2000) the FBI created a processing guide. Although the information is dated, it may be great place to begin your search, if you wish to explore some ideas, which are supported by academic and practical experience.

A while ago, The Canadian Society of Forensic Science created a resource entitled: ALL YOU EVER WANTED TO KNOW ABOUT FORENSIC SCIENCE IN CANADA BUT DIDN’T KNOW WHO TO ASK! I know that sounds like a lot, but in 2017 they provide a second edition of this, and it is an amazing reference resource. Check it out, and it can help you answer any questions you may have.

Recently one of my students asked me a question about some of the forensics behind Drowning Investigations. So, I thought I would make that the next post. This is just a summary, to act as an introduction to the idea of a drowning investigation, from a forensic perspective. To begin, please know the lead expert in a case like this will likely be the local Medical Examiner or Coroner. This can be one of the most diverse investigations, involving experts in anthropology, botany, entomology, toxicology, pathology, etc. But the lead will most likely be the Medical Examiner or Coroner, and they will need all the information you can provide. Overall in cases like this, it is the circumstances and context which are of extreme importance. Just because the body is in water, doesn't mean they drowned. And, even if drowning was the cause of death. Understanding the mechanism of death, to determine if it is an accidental death, suicide, or homicide can be a challenge; especially if you wish to prove it, beyond a reasonable doubt. But here are a few of the questions to explore in the investigation 1. Was the person alive or deceased when they entered the water? 2. Was drowning the cause of death? 3. What caused the person, or body to enter the water? And, here are a few of the things to look at when examining these questions, in addition to determining details for the circumstances leading up to the discovery: 1. Is there foam in the airway? - a whitish foam in the mouth, nose, etc. This may suggest drowning as a cause of death, but it can be present for other reasons too. 2. Amount of water in the lungs, and stomach? - if a person is deceased when they enter the water, it is less likely to find large amount of water or other debris from the water in the lungs or stomach? 3. Diatoms? - if there is water in the lungs and stomach, they may have diatoms present in their lungs, stomach, or bloodstream and tissues. These are single celled algae that exist in water, and may be compared to the water where the body was found. This can help to confirm location of the drowning, or determine if it was elsewhere. However, there is more to this, and this is where a forensic botanist may be a great resource! 4. Cadaveric Spasm? - This is an instantaneous rigor or stiffening that occurs at the time of death, and is not uncommon in drowning. The hands of the deceased may possess debris from the water, weeds, or other items and provide more circumstantial information. 5. Lividity? - Can indicate the position the body was in after death, as lividity set. Drowning victims can have a very characteristic lividity. These are only a few of the things to explore, if you wish to know more about drowning investigations. And, these largely pertain to the body. But it will be extremely important for the investigation to be as thorough as it can be, which means you had better examine the scene the body was found in, to determine if any other traces were left behind. This is a challenging and arduous task, for which help is always required! If you are unsure what a scene exam may look like ... imagine a grid beneath the water, and you job is to search it grid by grid, to the full extent of your abilities! Its a unique experience, and you never know what you may find!

We often see much about hair and fibre evidence on TV and in the movies. But ever wonder what the reality was for this type of evidence? Here are some amazing resources if you ever wanted to learn more than the very basics, and begin digging into the some of the details! Forensic Science Communications (FBI) - Jan 2004, Volume 6, Number 1: Microscopy of Hair Part 1(human) - July 2004, Volume 6, Number 3: Microscopy of Hair Part 2 (animal) - April 2009, Volume 11, Number 2: Forensic Hair Comparison If after reviewing those articles, you are interested to know more. I would highly recommend researching the limitations of the this type of evidence next. It is important with any type of forensic evidence, that you challenge and examine critically the strength of it. Hair can be a very controversial type of evidence, but it can also have a significant amount of value, if you understand it for what it may be!

On sites like this, or in investigation/forensic courses. There is always talk about case studies, where such forensic techniques were involved, and often these stories only explore the role that Forensics or the investigation played. However, there is so much more. If forensics and investigation is all you see, you've missed the bigger picture! To appreciate why forensic specialists and investigators do what they do, and why it needs to be done well, there is another perspective you need to see! Hear real life cases explored from another perspective, by an amazing investigative reporter: Nancy Hixt. https://curiouscast.ca/podcast/398/crime-beat/ Know I do not know Nancy, and have no reason to make this recommendation. Except to say, those I trust and respect, believe this is well done and is something everyone should hear, if they can handle it! Check it out, share it with others ... its a perspective, we can all learn from!

In the world of Forensics, like any legal topic, you must also have a great understanding of the legal environment in exists within. Here in Canada, like anywhere, that can be a daunting task. But there are a few exceptional resources out there for lay persons, police, or anyone really. Here are two out of my favourites list: 1. www.HenryWaldock.ca - Henry is an exceptional legal reference with an impressive CV. He scans case law on an almost daily basis, and shares cases with a summary of significant areas of interest. His ability to clearly summarize and highlight important case law decisions, is a great way to stay up to date, and ensure you understand the legal concepts involved. The information available on his site is beyond description. If you have any legal interests, bookmark this site, and visit it daily! 2. www.CriminalNotebook.ca - This is a website created by Peter Dostal, who Like Henry, is another of the exceptional legal minds of our time. His site provides a wealth of information on Criminal Law, which has a great search function to find your way through all the details. Again, this is another site to bookmark and visit daily. Between these two sites, you will likely always find what you are looking for! Now please know, I have spoken to both Henry and Peter, before. But neither would know me, and I am not recommending these sites for any other reason than they have been, and continue to be, an exceptional resource to know.

There is always much talk about the Polygraph in the world of policing. Although this is not commonly referred to as a forensic topic. It is a clear indication where a scientific principle, or idea, is applied to an investigation. That being said, there are more questions than you may be aware of for the science behind the Polygraph. To explore this further, there are many sources of information out there. But here are two you may wish to begin with: - The Polygraph and the Detection of Deception (Meijer, Ewout & Verschuere, Bruno. (2010). The Polygraph and the Detection of Deception. Journal of Forensic Psychology Practice. 10. 325-338. 10.1080/15228932.2010.481237) - The Polygraph and Employee Selection: A review of the literature. (this one is an older source, but gives a great history and insights into what the idea was behind it in the past)

Ever want to know more about how more about Forensic Handwriting? A great place to begin may be a comprehensive report offered by NIST: Forensic Handwriting Examination and Human Factors: Improving the Practice Through a Systems Approach. Note: It is a comprehensive 246 page report and recently published (Feb 2020). However, even if only looking for an introduction, it may offer some great insights about the conventional process in Chapter 1 alone. Summary here: https://www.nist.gov/programs-projects/forensic-handwriting-examination-and-human-factors Full Paper here: https://nvlpubs.nist.gov/nistpubs/ir/2020/NIST.IR.8282.pdf
