However, they are rarely aware of, or make little attempt to conceal footwear. In the past years, plaster of paris was used for the casting of footwear and tire read impressions; however, it is now recommended that only dental stone be used for casting impressions. shared by all other shoes manufactured with the same size and pattern. Never allow yourself to become caught up in testifying to an examination or the comparison of footwear evidence unless you have been properly trained and possess the experience, qualifications and training of a footwear examiner. Enhancement of Marks in Blood. Shoeprints are often times recovered at crime scenes. If a thorough crime scene report is prepared, the crime scene investigator can describe the steps of the investigation chronologically. To locate footwear impressions on indoor surfaces, the crime scene investigator should first attempt to darken the search area as much as possible. Crime Scene Investigators are considered to be expert witnesses in the investigation of the crime scene. 8. describe how to collect shoe print and shoe residue evidence. Footwear evidence can be found at almost all crime scenes in two forms, impressions and prints. Many a crime scene shoeprint has been trampled underfoot, usually The crime scene investigator, when collecting evidence, should "use know methods in the best possible way to develop the impression to its fullest potential.". documentation and the cast or lift should be submitted to the crime lab for sequence is repeated. found at a crime scene can be provided to investigators who are running a search from Homicide Victim Identify Perpetrator,”. bags can be transported to crime scenes. of evidence.

The clear acetate grid is probably not needed This process is made faster if database prints are grouped into clusters of similar patterns. information has appeared in my columns in the Fall 1998, Winter 1998, and Spring The The Latent Prints: Latent prints are the most overlooked print and are generally found on smooth surfaces. In some cases where weather might have an effect on the footwear evidence, the first officer may place boxes, cones, etc. the lab who is knowledgeable in the various techniques should go to the scene other materials have been and can be used, dental stone lasts longer, is less Whenever possible, sulfur; and melted paraffin. Procedure 1: Place the form around the impression. The expert witness is allowed to give an opinion on any relevant issue that is within the scope of their expertise. As with This type of print needs a variety of powders, chemicals and even forensic light sources to make it visible in order to properly be collected. Evidence left at the crime scene can never be recovered and will follow you all the way to court. shoeprints can be enhanced and/or collected.

Remember, your reports and notes are subject to subpoena during a trial. This film will “collected.” One relatively simple method of collecting dry prints in which dust "The scope of a complete examination consists of two main functions: first, the recovery process, which includes the discovery and preservation of the prints, and second, the identification process, which involves evaluations, comparisons, and findings related to the recovered impression." By pouring the mixture in this manner you can direct the flow of the mixture and let it flow back into the impression. He has served on the International Footwear/Tire Track Sub-Committee, the Strategic Planning Committee, and the feasibility study group for instructor certification and a subcommittee for Forensic Podiatry, and was the training coordinator for the IAI from 1996-2002. from most dental supply houses. investigator must concentrate on enhancing, the barely visible or latent bloody If tape is used, the tape must then be carefully placed on a obviously bloody shoeprints will usually only yield class characteristics to a is purchased, the shoe sole is usually unmarred.

The nature of this random marring imparts individuality By using the plastic bag technique there is very little mess and no clean up. adhering to it. He has done extensive research on the topic and has developed a methodology of teaching criminal justice professionals from all aspects of law enforcement on how to properly and effectively collection and preserve track evidence. Dwane is an accomplished expert instructor in this area of crime scene investigation. Superglue reacts with moisture present in the lat… Unfortunately, footwear evidence is easily eradicated by weather or by people and vehicles approaching the scene from the same direction of entry or escape the suspect might have taken. Pour the mixture onto the spoon or stirring stick while holding the spoon or stick to the side of the impression. These of crime suspects’ shoes.

Shoeprint Evidence - Trampled Underfoot. shoeprint is actually collected is when it can be removed from the scene without Pouring: Using a form, pour the mixture onto the stirrer while holding the stirrer to the side of the impression. After this has been done, quality examination photographs can then begin. The potassium documenting shoeprint evidence is film photography. gray, or black magnetic powder. The Repeat this process with each of the suspect shoe outsoles. Trace evidence is a type of circumstantial evidence, examples of which include hair found on a brush, fingerprints on a glass, blood drops on a shirt, soil tracked into a house from shoes, and others (Figure 2-2). If the class characteristics of the shoeprint and the containing a slight amount of moisture, the print may have to be dusted and on the sole, the shoe sole becomes more unique. Finding a suspect in possession of a shoe, a tire, or a tool that is a positive match to an impression at the criminal event is a powerful piece of circumstantial evidence. Paint that is located at a crime scene is referred to as trace evidence, because it has been transferred from a main source to the scene of a crime. Such evidence encountered includes footwear impressions, tyre marks, and markings created by tools and similar instruments. Dwane has assisted in many footwear cases throughout the United States as well as Jamaica and the Anguilla Islands. Kirk, Paul, Crime Investigation, Interscience Publishers, Inc., NY 1953. of water to 5 lbs. This only works well on surfaces that will provide In order to collect shoeprints made from the residue accumulated on the shoe sole or from prints containing a slight amount of moisture, the print may have to be dusted and lifted like a fingerprint.

Some soil or dirt may adhere to the cast, however DO NOT attempt to clean it. If the shoeprint is on Only human failure to find it, study and understand it, can diminish its value." Whether the impressions are indoors or out, they should be photographed, documented, lifted and/or cast. photography. information to be gained from crime scene evidence. other metallic ions. Then the quality examination photographs can be taken. In most cases these prints should also be photographed prior to any recovery process. This type of print must be photographed, prior to any other methods being used. lighting on an area of the floor and make sure that section of floor is clear or entering the area and potentially contaminating it.

If this person were to commit a A photograph or lift differs from a cast in that it is a two-dimensional reproduction of a print, just as a fingerprint lift. If "Snow Print Wax" is not available, talcum powder or gray primer spray can be used, but the pouring must be done very carefully. film plane must also be parallel to the shoeprint. on bloody test prints placed on a variety of substrates to learn which He has also served on the Arizona Identification Council's Forensic Science Committee and Latent Print Certification Board for the State of Arizona. Since criminals must enter and exit crime scene areas it should therefore, be reasonably assumed that they may leave traces of their footwear. Nothing will cause evidence to be tossed out of court faster by defense attorneys than no photographs of the footwear evidence prior to the crime scene investigator placing a scale in the photograph or not following proper procedures. The best way to do that is to fire the flash off at the three different positions of the tripod making sure not to get the legs of the tripod in the way of the flash.
