So surprised to read this. Why is this the case? I believe many of the victims' families are not aware of this support. Federal government needs to do a better job of communicating what's available.

Even with advances in computer software and drawing techniques, Forensic Sketching has earned a pop culture reputation for being much more useful than it truly is. Computer generated images of a possible suspect boast only a 5% success rate, while artist-drawn sketches find only 9%. Research suggests that witness prejudices about a person's appearance, whether intentional or not, can skew their recollection of a suspect's features and can even generate an image of the wrong face: https://www.youtube.com/watch?v=x4L9hgdcyno

When Lynda White's body was discovered with one arm missing five years after her disappearance, investigators might have considered the possibility of ritual activity. Ritualistic killings can be separated into two categories: killing for religious or spiritual purposes and the ritualistic behaviours of serial killers, and can involve the taking of 'trophies' or 'souvenirs' from a victim. While ritualistic killings are extremely rare, Mike Arntfield believes investigators should consult with experts in ritual activity to better analyze certain cases: https://www.youtube.com/watch?v=v8s3q5WUfZk

There are many small details within a crime that can reveal whether an attack was planned or spontaneous. One indicator is a killer's "Dumpsite", the place they leave a victim's body. If the site is easy to find, it often means the killer was disorganized and acting impulsively. If it is hidden, it is typically a sign that a killer had preselected a location, and even a victim. https://www.youtube.com/watch?v=kKpCuUAJONc

In the first 48 hours of a crime, investigators must move quickly and intelligently to piece a case together. One of the most valuable tools to use is a "Victimology", a profile created to detail a victim's history and bevahiours. It helps investigators discover why and how a killer might have attacked, as killers often develop similar profiles in order to trap their victims: https://www.youtube.com/watch?v=pKTFe2REFRw

Another previously unaired extra is up on Youtube. In this clip, Mike Arntfield explains how the compliance of a witness can make or break an investigation: intelligent questioning can often be the key to getting information from a reluctant source. But though many effective interrogation techniques exist, sometimes the most important skills just can't be taught: https://www.youtube.com/watch?v=YM08rGyoqCo

Bloodstain Pattern Analysis is one of the most specialized and sought-after areas of forensic investigation. It involves complex applications of biology, physics, and chemistry, and can reveal how and where an attack occurred by examining a sample's pattern, colour, and angle. While bloodstain pattern analysis is not necessarily new, it has become much more sophisticated over the last ten years: DNA analysis has matured and has demonstrated how the blood found at a crime scene can tell a story, whether through movement of the blood itself or the cells contained therein. Mike Arntfield explains more about how it works, and how it was important for the team to consider in the case of Clyde Frost: https://www.youtube.com/watch?v=SLdNPi8qdl4

The National DNA Databank was created in the year 2000, and was the first technology to allow scientists to compare DNA collected from a crime scene to the DNA samples of convicted offenders. This and other advances in DNA collection have played a significant role in discovering new evidence in cold cases, though challenges still remain: https://www.youtube.com/watch?v=YSMTJd7FtYw
