Building a Face, and a Case, on DNA<\/strong><\/em><\/a><\/p>\n

\nThe police in Columbia, S.C.,\u00a0 released this sketch of a possible suspect based on DNA left at the crime scene. Parabon NanoLabs, which made the image, has begun offering DNA phenotyping<\/a> services to law enforcement agencies.<\/small><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

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.<\/p>\n

Nonetheless, the police in Columbia, S.C.<\/a>, last month released a sketch of a possible suspect. Rather than an artist\u2019s rendering based on witness descriptions, the face was generated by a computer relying solely on DNA<\/a> found at the scene of the crime.<\/p>\n

It may be the first time a suspect\u2019s 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.<\/p>\n

Already genetic sleuths can determine a suspect\u2019s 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.<\/p>\n

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…<\/p>\n

…Law enforcement authorities say that information about physical traits derived from DNA is not permitted in court because the science is not well established. Still, the prospect of widespread DNA phenotyping<\/a> has unnerved some experts.<\/p>\n

Duana Fullwiley<\/a>, an associate professor of anthropology at Stanford, said that she worried that use of such images could contribute to racial profiling. She noted that Dr. Shriver developed his system by analyzing the DNA and faces of people with mixed West African and European ancestry.<\/p>\n

\u201cThis leads to a technology that is better able to make faces that are African-American,\u201d she said. The image produced in the South Carolina<\/a> case, Dr. Fullwiley added, \u201cwas of a generic young black man.\u201d<\/p>\n

Dr. Shriver<\/a> said he initially studied people of mixed European and African ancestry, many of them from Brazil<\/a>, because that made the analysis easier. His more recent research has involved people of many different ethnicities, he said…<\/p>\n
