Possible, but highly unlikely. There have been instances in which a procedure using small-particle reagent (SPR) has developed latent prints on surfaces that have been exposed to water contamination. Perhaps not after that length of time, but the source of the latent residue would be the prime consideration in development. However, and perhaps unfortunate in your case, it is recommended that items found underwater be kept underwater and only removed when the latent processing procedure can be started. Of course, the old adage in latent print processing is "You do not know unless you try."

A steel or iron pipe 8" in diameter is believed to have been submerged in a Wisconsin lake for less than one year but longer than 30 days. It was removed from the lake within the last couple of days. If there are fingerprints on the pipe, they could be extremely helpful in proving defendant's involvement in a potentially criminal act that certainly creates substantial civil liability.
Can anyone tell me whether it is possible - or likely - fingerprints (if originally present on the pipe) would still be recoverable in such a circumstance? Are there specific techniques - beyond the ordinary - that would enhance the possibility of recovery that could, or should, be employed?
