Documents may contain vital clues to solving a case. This section of forensic science deals mainly with fraudulent documents. Such documents may include suicide, blackmail or extortion notes to name a few. Most fraudulent documents are created to disguise the handwriting and ultimately to fool people. The documents are analyzed by eye, by hand lens and several methods including microscopy and chemical analysis of the paper and ink. The most common clue of fraudulent handwritting is the poor line quality of the handwriting (it loses the smooth lines and becomes uneven). The most common methods of trying to disguise the handwriting are using the reverse slant of writing, changing capital letters or using the opposite hand. A good way to tell if a document is disguised is by looking toward the end of a document to see if the style remains the same. Try using the methods above to conceal your handwriting in a letter. You will see at the end that it gets harder to keep the same style of writing throughout.
