Fingerprint Concealment Technique?
My department has encountered several vehicle burglaries where it appears that the suspect(s) have sprayed a powder type aerosol to the surfaces that they planned to touch (door handles, glove box handle, area surrounding the stereo, ect). Obviously, the powder fills the ridges on their fingertips - preventing any ridge detail in the print. One would think that gloves would be easier to use to conceal their prints, but would be quite obvious if the suspect(s) were stopped on foot in the area while possessing gloves in a warm climate.
Is this a new trend? Anybody heard of this method?
