Does superglue fuming destroy DNA?

In the May-June 2008 issue of Evidence Technology, the article “Can You Find It?” made reference to the fact that it could be worth your time to send an item of evidence to the laboratory for DNA testing—even after it has been processed for latent prints using cyanoacrylate (superglue) fuming. This statement raised eyebrows for some readers who had gotten the opposite impression through word of mouth or from talking with their own forensic laboratory. It is always best to communicate with your laboratory and follow their guidelines and standard operating procedures. To clear up any confusion, however, here are some references that may be useful:

If you have had any luck—good or bad—getting DNA profiles from evidence processed with superglue fuming (or any other fingerprint development technique), we would love to hear about it so we could share your experiences with the rest of our readers. Send your comments to our editor, Kristi Mayo:
