There were no known eyewitnesses to the murder of a young woman and her 3-year-old daughter four years ago. No security cameras caught a figure coming or going.
Nonetheless, the police in Columbia, S.C., last month released a sketch of a possible suspect. Rather than an artists rendering based on witness descriptions, the face was generated by a computer relying solely on DNA found at the scene of the crime.
It may be the first time a suspects face has been put before the public in this way, but it will not be the last. Investigators are increasingly able to determine the physical characteristics of crime suspects from the DNA they leave behind, providing what could become a powerful new tool for law enforcement.
Already genetic sleuths can determine a suspects eye and hair color fairly accurately. It is also possible, or might soon be, to predict skin color, freckling, baldness, hair curliness, tooth shape and age.
Computers may eventually be able to match faces generated from DNA to those in a database of mug shots. Even if it does not immediately find the culprit, the genetic witness, so to speak, can be useful, researchers say.
That at least narrows down the suspects, said Susan Walsh, an assistant professor of biology at Indiana University-Purdue University Indianapolis who recently won a $1.1 million grant from the Department of Justice to develop such tools.
But forensic DNA phenotyping, as it is called, is also raising concerns. Some scientists question the accuracy of the technology, especially its ability to recreate facial images. Others say use of these techniques could exacerbate racial profiling among law enforcement agencies and infringe on privacy.

I knew it....another renegade Mennonite from northern Indiana, probably on a cross country crime spree.
I anxiously await the results of double blind testing, in which the DNA of random individuals of many different ages is submitted for face synthesis, and then random third parties try to match the synthetic faces with the actual faces of the people from whom the samples were taken.
It will be interesting to see those scores.
“Others say use of these techniques could exacerbate racial profiling among law enforcement agencies and infringe on privacy.”
How, if ones innate characteristics are unique, is racial profiling going to be a problem?
That Mennonite is probably from Inola, Oklahoma. ..
A black male with dark eyes and hair. That really narrows it down, to 10 or 20 million.
How can they get an idea of approximate age from DNA??
Not surprised at the pictures. Not surprised at all.
But now we have a problem.
Racist computers.
‘Predicting a suspects age is not out of the question, either by analyzing markers that shut off certain genes as people grow older, he said.’
