There are three specific areas where having ancestry information from DNA can assist investigators. It can identify the physical characteristics of an unknown DNA contributor, identify the physical characteristics of a skeletonized unknown victim, and narrow the pool of "persons of interest" based on the physical characteristics of the offender determined from DNA at the crime scene. This article briefly describes three cases in which these capabilities of ancestry DNA assisted in solving the case. In addition to determining ethnicity and associated physical features, ancestry DNA shows promise in providing information on other physical features of a DNA contributor, such as skin, hair, and eye color. http://www.ncjrs.gov/App/publications/Abstract.aspx?id=241771
