Recovering fingerprints from clothing
The way described below seems to be an effective one while recovering fingerprints from clothing. This method works by placing the fabric in a vacuum chamber. Then a fine layer of evaporated gold is spread over the fabric, followed by an application of heated zinc. The zinc attaches to the gold layer where there are no fingerprints, allowing the fabric where contact was made to show through.
The technique could be useful in targeting areas of clothing where a victim was grabbed or pushed.
