How and why was the crime committed? I allow them to discuss their ideas at their table group and then call on volunteers to share their thoughts.
When a group thinks they have a match, I show them the samples and they determine whether or not they are correct. He discusses the steps that a forensic document examiner follows, including analysis, comparison, and evaluation. For example many architect students are taught to write using only block, all capital letters.
Probable Identification - still a strong conclusion, combination of similarities points strongly to one writer with no fundamental differences, leaves only theoretical possibility of another writer.
The principle of identification is that two or more writings are the product of one writer, IF the similarities, taken in combination, are sufficiently individual and there are no fundamental differences.
Investigators use many types of clues together to narrow down the potential pool of suspects. The line quality is the appearance of forensic handwriting analysis lesson written stroke, caused by basic movements and the manner of manipulating the writing instrument.
Ina parcel exploded as it was being opened at campus security at a North-western University. Is the document genuine? Example The handwriting examples below are from two different writers.
In the world of forensic analysis, which includes crime scene investigationDNA testingfiber analysis, fingerprint analysis, voice identification and narcotics analysis, to name just a few of the disciplines, handwriting analysis fits into the area of questioned documents.
Positive findings can be made in most examinations, given that sufficient questioned material and known samples are available.
Explore 30 minutes Next, I ask the students to list anything they know - or think they know - about the field of forensics. Before learning about the procedures that investigators use to solve a crime, we must first learn about WHO works on these teams and conducts these procedures. Hand or shoe prints can be analyzed to provide the approximate height and stride of the suspect.
If you have a questioned document and have a suspect, but have to request a handwriting sample from the suspect, they may obviously try to alter their writing. Before we discuss how the documents are examined, there are five different conclusions that an examiner can reach that we must learn about.
I explain to the students that in addition to the type of paper and ink being used as well as the content, spelling, phrasing, punctuation, and grammar, investigators look closely at several other characteristics when they are examining handwriting for clues.
The examiner must make a judgment in each case by evaluating the totality of the documents. Like fingerprinting, there are no known statistical frequencies for handwriting analysis.
There are variations in angularity, slope, speed, pressure, letter and word spacings, relative dimensions of letters, connections, pen movement, writing skill, and finger dexterity.
Of the two cases discussed in this lesson, in which do you think document analysis was the most useful? This is a shorter read and should not take more than 10 minutes to complete.
The Science of Handwriting Analysis The science of handwriting analysis is based on the premise that no two individuals can produce exactly the same writing and that an individual cannot exactly reproduce his own handwriting, otherwise known as variation.
This can be anything from written letters, drivers' licenses, contracts, wills, passports or lottery tickets! Like fingerprinting, there are no known statistical frequencies for handwriting analysis.
Handwriting Analysis Practice Sheet. Writer should be sitting comfortably at a desk.
Web Sites Tracking the White Salamander - Chapter 5 Scroll down to page 3 of this book chapter, which makes reference to Irving's forgery. The bomb typically had the initials "FC" punched into it. To do this, I pair students up again and have them access the CSI: Do you think the forgery was well done?The partners study the samples and analyze each one, using the Handwriting Analysis Practice Sheet as a guide.
After analyzing the samples, I collect them again, leaving the students only with their analysis.
Counterfeit Video Response Currency Pre-Test. The Scientific Foundation for Handwriting Analysis The FBI Laboratory’s Questioned Documents Unit uses the following conclusions in handwriting comparisons: The implications of kinesthetic factors in forensic handwriting comparisons, Doctoral thesis, University of California at Berkeley.
MODULE 3: Handwriting Analysis This is the third lesson for the Forensic Science 4-U crime scene: The Case of the Ransom Note. This is Module 3 out of Students will discover how to use the scientific method to perform a criminal investigation, as well as, how to use math and science skills as a crime scene investigator.

HANDWRITING ANALYSIS. Do you have what it takes to be a document. Lesson 4 - Handwriting Analysis Many people have this belief that a person's hand writing can reveal personality traits about the person; little circles above an 'i' means they're very open or sharp edges and angles mean they have a temper.Download
