US Military
United States Fish and Wildlife Law Enforcement
State and local
Medical Examiners Office
Private Industry
Colleges and Universities

slide8. How do I become a forensic scientist? Bachelor’s degree (science)
Practice your speaking skills
Practice your note-taking skills
Learn how to write understandably
Have an intellectual curiosity
Have a strong stomach
Personal integrity!
Start thinking about what you’re interested in (science, art, history, etc.)
Try to get involved in anything you can related to your interests (camps, classes at school, research online if possible, internships and shadowing) Copyright © 2021, Kelly Knight , All Rights Reserved<br>
slide9. Questions? Copyright © 2021, Kelly Knight , All Rights Reserved<br>
slide10. What type of forensic evidence could you possibly find at a crime scene?<br>
slide11. Crime Scene Collection Search the scene
Look for clues
Take notes
Collect evidence
Proper packaging/storage
Take evidence to lab Copyright © 2021, Kelly Knight , All Rights Reserved<br>
slide12. Forensic Biology What is DNA?
Holds the code for every cell in your body
Like an instruction manual Copyright © 2021, Kelly Knight , All Rights Reserved<br>
slide13. Where can we find DNA?<br>
slide14. Blood testing-Sero-Stix Fast & easy to presumptively identify blood
Use these to determine if any suspected stains are blood or not
Patch on end of strip contains test reagents
Procedure:
Moisten swab with water
Swab suspected stain
Press stained swab to test patch for a few seconds
Positive=Green to deep blue color Copyright © 2021, Kelly Knight , All Rights Reserved<br>
slide15. Police Report: At approximately 0900 hours, the Suspect entered classroom and burglarized locker of Victim. Suspect proceeded to steal the Victim’s iPhone and eat their lunch. Suspect fled scene upon entry of Janitor. Process crime scene for forensic evidence. Copyright © 2021, Kelly Knight , All Rights Reserved<br>

slide22. Conclusions Now get together with your group and discuss what types of conclusions you can make in this case…
What do we know from the evidence?
Who drank from the juice?
Who left the items at the scene?
