In a post on my blog, a follower mentions the term “face DNA” in the context of a police officer using it. My research on this  finds only that experiments are being conducted to use DNA to reconstruct the facial appearance of a person. I’m wondering if anyone out there has any further explanation of  this term. (including perhaps the police officer in the N.H. State Police Department who is purportedly the one who used it)

The comment, by the way, is in the public domain on my website under comments to blog posts.
