International Forensic Automotive Paint Data Query (PDQ) Paint, Automobile Identification Royal Canadian Mounted Police (RCMP)-- Forensic Laboratory Services The International Forensic Automotive Paint Data Query (PDQ) database is a centralized, searchable database of chemical and color information of original automotive paints. Search results provide make/model/year information. PDQ contains foreign and domestic automotive paint samples from ~13,000 vehicles and ~50,000 layers of paint. Most paint samples consist of four layers typically used for an automotive job. Contains majority of post-1973 vehicles marketed in the US. Access is granted through a program updated and released by RCMP annually through a CD release. Law enforcement agencies interested in PDQ who are not already members can contact PDQ directly by email. Partnering agencies also have access to physical samples by request. Use of the PDQ is for bona fide law enforcement agencies only that perform forensic paint examinations as part of criminal investigations. "Payment" for access to the database is the submission of 60 samples to PDQ each year. In addition, users must sign a non-disclosure agreement. Every accessing institution must submit 60 paint samples per year, these usually come from vehicles at body shops or junk yards or manufacturers. Samples are also collected directly from some automotive companies. Samples are analyzed for their identifying chemical properties, and this information is stored digitally. Physical samples are available by request (see more information). Email PDQ:

National Automotive Paint File (NAPF) Paint, Automobile Identification Federal Bureau of Investigations (FBI) -- FBI Laboratory A physical collection of automotive paint panels acquired and maintained by the FBI's Chemistry Unit for use in casework. NAPF is a physical collection of paint color standards and/or full system paint panels (as a vehicle would be painted, not just the top coats). It contains approximately 14,000 automotive paint panels. NAPF is used in an investigation to make a physical comparison of evidentiary paint chips to known paint colors to aid in identifying possible vehicle makes and models in hit-and-run investigations. The FBI Lab may be able to provide small samples of specific vehicle colors to other law enforcement agencies if that agency has some knowledge of the specific color or model they are seeking. Automotive manufacturers provide these physical samples free of charge to the FBI Lab for all vehicles available for purchase in North America. This does not include commercial vehicles such as trucks, buses, motorcycles or RVs. NAPF is not a database; physical samples are available. Diana Wright

National Forensic Tape File (NFTF) Tape Federal Bureau of Investigations (FBI) -- FBI Laboratory The National Forensic Tape File is used for determining the manufacturer and/or product for duct tape sourcing requests and is also a repository for samples used in the FBI duct tape and electrical tape discrimination studies. ~500 tape samples stored in-house in plastic bags and plastic bins in a storage cabinet. Physical properties and/or chemical composition can be searched in SLICE software to determine potential manufacturer/product candidates, and then those candidates can be pulled out of NFTF for a direct comparison to the unknown sample. The Florida Department of Law Enforcement (FDLE) and FBI both use SLICE software to interact with digital tape records. - FDLE and FBI are willing to share their digital records with other forensic scientists that have SLICE and are willing to share/exchange samples.- For a laboratory without the SLICE software, the FBI can conduct the analysis for them as long as it adheres to the case acceptance policy. Case Acceptance Policy: Usually if it's a case that has FBI jurisdiction, they will accept it and perform the analysis. If the lab has its own capabilities, then it must do the analysis itself (but FBI and FDLE will share/exchange data and samples). Manufacturers provide rolls free of charge (majority of samples) or samples are purchased. A new roll is assigned a sequential number, put into a storage cabinet, its paperwork is filed, and then it is analyzed and data is put into SLICE. Digital records can be shared through the SLICE software. Physical samples are maintained in-house. Andria Mehltretter

Polyethylene Repository & Information Database for Evdience (PRIDE) Plastic Bags Federal Bureau of Investigations (FBI) -- FBI Laboratory Repository of polyethylene reference samples. Examples include trash bags and sandwich bags. Database can be used to determine the possible manufacturer of a bag used at a crime scene. Collection includes approximately 1,000 samples of polyethylene bags. There is a standalone system at the FBI Laboratory Questioned Documents Unit. The QDU will search the system to fulfill outside requests. Outside agencies submit the questioned specimen for QDU to do analysis. No cost to access; outside law enforcement agencies can submit requests to the FBI. Samples were obtained as part of a research project for development of the database. Additional samples are provided by the program manager. Submitted samples are not added to PRIDE because manufacturer information is unknown. Digital records and physical samples.

SoleMate Impressions Foster + Freeman (commercial) SoleMate footwear records include brand, model, footwear type (e.g. trainer / athletic shoe, boot, shoe, sandal, wellington / gumboot), availability, a print of the sole unit, a photograph of the sole unit and photographs of a range of uppers, where applicable. Each record is coded with searchable shapes, logos and text found on the print. As of today, SoleMate contains approximately 32,000 shoes and 1,100 brands of sports, work, and casual footwear. Footwear from different brands using the same sole unit, or from the same brand with small differences such as a change of logo, are linked together to allow the user to immediately see variations of that sole unit. The user specifies shapes, logos and text that match the questioned print and searches these against the coded records in SoleMate. The archive is provided on a memory stick, not a DVD, and there is no online purchase available. Foster & Freeman liaise with manufacturers and distributors to collect footwear data up to 12 months before the beginning of each new season, thus allowing time to enter it into SoleMate and distribute it to users in time for the start of each new footwear season.

TSWG Sponsored FIU Glass Database Glass, Elemental Analysis Florida International University, sponsored by the Technical Support Working Group The database assesses the relative frequency that two glass samples from different sources would have the same elemental profile. The purpose of this database is to provide glass examiners a view of the frequency of occurrence of elemental composition for ~700 different glass samples originating from different sources. The database contains elemental analysis data for 12 elements for ~ 700 glass samples from manufacturers, distributors, and vehicle junkyards. Samples include: containers, float, headlamp, and vehicle glasses. The database is not designed to be searched for casework in the way that other forensic databases (i.e. PDQ) but rather, it is to be used by researchers to estimate the probability of a random occurrence of elemental composition for different glass sources. Two plasma mass spectrometers are used to perform an elemental analysis of glass. Freely available to agencies and researchers with a reasonable cause. Samples are collected from manufacturers, distributors, and vehicle junkyards. The data was collected from a single laboratory (FIU) as part of a research project. Digital data records.
