One of the most overlooked forms of physical evidence at the crime scene is impression evidence. This is largely due to a lack of specific training in the proper search, collection and preservation techniques and procedures.

Locating and recovering obvious impressions from mud, dirt or blood are usually accomplished, but dust prints found in many indoor crime scenes are ofter overlooked and many times damaged or obliterated.

By using the Electrostatic Dust Print Lifter Kit, prints left in the dust of a floor, light soil from a criminal's shoes, or impressions made on overlooked areas such as dusty walls or doors can be recovered.

The ESP900 Electrostatic Dust Print Lifter consists of a high voltage power supply/control unit, a nickel-plated steel ground plane and a metalized lifting medium. Older electrostatic models required the use of two lifting mats—one positively charged and one negatively charged. Our latest electrostatic lifter uses only one metalized plastic sheet and a metal ground plane. As high voltage is applied to the lifting mat, it takes on a negative charge and the ground plane becomes positive. Any dust present under the mat will take on a positive charge and will then be attracted to the negatively charged collection mat. A dust print that is transferred to the lifting mat will appear as a precise mirror image of the original print and lifts made from rough-surfaced floor tile or irregular flooring of any kind are facilitated using this method.
