Hair, fiber and document analysis!
Frank Abagnale
We learned about one of the world's most famous prolific forgers of checks and documents. His life is profiled in the movie, "Catch Me If You Can". It is estimated that he flew over 1,000,000 miles as an airline co-pilot using forged documents between the ages 16-18. He also forged documents and pretended to be a doctor, a lawyer and professor!
Medulla!
The medulla is the innermost layer of a hair. It can only found in animal hair (including humans), but not in all animals. In very light hair, such as blonde or white, the medulla is often absent as in the middle hair in the picture.
Odd microscope "fibers"
In talking about fibers, we are often talking about analyzing them under microscopes. In this image, you see some fibers with quite an interesting look about them. This is actually used dental floss as seen under an electron microscope. Yikes!

Late work and Synchronous Chat Sessions....
Also, I would like to once again cordially invite you to our synchronous sessions on Tuesdays! I am there each week at 12pm for the Forensics AB class and 1pm for the Forensics A class. I go through powerpoints, case studies, reviews and will gladly help any of you one on one with questions or assignments as needed! Lately, I have been in the sessions with no students attending! I know that many of you are in school and busy, but if you can make it, come join me! I posted a poll question on our course page asking if it would be better to change the time or day of our sessions for you to attend. Make sure that you cast your vote on that poll (it is only ONE question!). Of course, the sessions are not mandatory, but I want to make sure that I am available to everyone who wants to attend! For those unable to attend, I always post a link to the recording on our course page in the links box. They are labeled with date and topic for your convenience and will remain there all semester. Additionally, you may email me questions or topics that you would like me to cover in the synchronous sessions!
