Whenever possible, the forensic investigator should examine the particular machine(s) suspected to have been used in creating questioned documents in order to compare individual characteristics. Investigators called in forensic document ink to examine the plastic garbage bag in which the victim was found. However, in comparison to typewriters, it is rarely possible to link the questioned document back to the specific computer on which it was written. The American Society for Testing and Materials (ASTM) publishes standards for methods and procedures used by Forensic Document Examiners. Whenever typewritten or machine-produced documents are called into question, each page of the document should be carefully compared to all of the other pages of the document, and, whenever possible, compared to collected specimens from the source machine(s). In this technique, a small cutting from the questioned document is dissolved in a solvent and analyzed. Signatures may be of particularly poor quality if they must be reproduced in front of the person intended to receive or verify it (e.g., signing a credit card receipt in front of a storekeeper). A new building complex was occupied in March 1987 when the Ballistic and Question Document Unit, which before this had resorted under the SA Criminal Bureau, were amalgamated with the FSL. An EDD uses applied charges and toner to visualize areas of indented writing, making them csi to the eye. The most commonly used EDD is the electrostatic detection apparatus (ESDA), which uses an electrostatic charge and toner to visualize areas of indented writing that may have been left by erasures or pressure from writing on top of the document in question. The color of a piece or pieces of paper may be compared against a white standard or through a side-by-side comparison. ESR has forensic laboratories in Auckland, Wellington and Christchurch.

Typical strategies employed when someone is attempting to disguise their handwriting include changing the slope of the writing or lengthening the terminal strokes and adding curves or other embellishments. It is where scientists use techniques and knowledge from these sciences to study criminal acts, including using science to help determine who committed a crime. This can be done with vary degrees of sophistication and success. As compared to a freehand copy, tracing a signature often results in a very close approximation of the original; in fact, they may provide a more exact copy of a signature than would normally be found due to natural variations in handwriting. A) Biology unit _____ Hair samples found on a victim’s clothing. : After successful Forensic Analysis of your documents, We will dispatch you ‘Forensic Examination Report or Expert Opinion’ by Speed Post, Registered Post, Priority Mail, Through Messenger or Direct … Individuals also will display minor variation in their signatures across documents, so forensic standards indicate that investigators obtain 20-30 repetitions of signatures, 15-20 repetitions of bank checks, and 3-4 repetitions of entire written documents for comparison purposes. However, there will likely be evidence of laborious production, such as signs of uneven pen pressure, pen lifts, and poor line quality. Acknowledgments. Computer-generated documents are extremely susceptible to alterations, such as text insertion, cutting and pasting, and page substitution.

Secret Service Forensic Laboratory contains handwriting samples from tens of thousands of writers. Forensic examiners are often required to evaluate the authenticity of an individual’s signature, particularly in the case of contested wills or other legal documents. Liquid chromatography may be conducted in order to determine the chemical composition of inks used in a document. Writers may also write with their unaccustomed hand in order to disguise their handwriting, which usually results in a drastic reduction in skill level characterized by a loss of fluency and larger letters than when written with their dominant hand. These may be manufacturing defects, such as defective die material, distortion, or misalignment, or may be a result of use (e.g., accumulated ink, dirt, or fibers) or misuse. For example, under certain light sources combined with an inks filter, a document containing information written in ink that has faded over time may be enhanced or processed to appear darker and therefore more legible. Tracing paper may be placed over the genuine writing or a light box may be used to illuminate the underlying writing so that the overlying paper may be traced upon.
