Vehicle theft is often facilitated when an offender alters the vehicle identification number (VIN), in most cases by grinding off the identification number and restamping a new number over the same area and in a few other cases by fixing false identification plates over the original VIN plate.
Abstract
Front-end portions of vehicles usually contain VINs stamped into the metal. The entire front end of a legitimate vehicle can be welded to the rear portion of a stolen vehicle to give the new hybrid a new identity that is very hard to dispute. Vehicles are also re-identified by simply welding a new VIN plate over the original plate to give a genuine appearance. Experiments were conducted to assess the usefulness of x-rays in solving problems associated with stolen vehicle identification. Field trials using a Mitsubishi Lancer sedan, a Ford Falcon sedan, a Honda Civic hatchback, and a Honda Civic sedan showed the positioning of the x-ray source determined the quality of the image obtained and the exposure time required. Results showed that the x-ray equipment detected weld joins and false VIN plates and that x-ray methods were cost-effective and easy to use and obviated the need to remove large areas of paint from expensive vehicles. The authors recommend that x-ray methods be adopted by investigative bodies, vehicle registration authorities, and insurance companies as part of the arsenal for fighting vehicle theft. 13 figures
