Abstract
A patent has been filed through the Canadian Police Research Centre to cover a development made by the Royal Canadian Mounted Police Forensic Identification Support Section. This development allows one to detect cyanoacrylate developed latent fingerprints. D.A. Wilkinson, A.H. Misner and J.E. Watkin collaborated their efforts to develop this TEC dye. The dye is created when three molecules of thenoyltrifluoroacetone bind to one atom of europium in the solution. The TEC dye is applied to fingerprints after exposure to CA under vacuum. There are two different methods to develop the prints the first is for hard surfaces and skin and the other is for large surface areas, which includes plastic bags. One of the problems with using cyanoacrylate on its own to develop fingerprints is that it cannot develop weak prints to a stage where they are visible to the naked eye. Presently permission is given to accredited police agencies only, to make up and use the solutions for theirs investigative purposes. In the future the material may be supplied commercially as a package.
