New DNA technology can generate better profiles from small and degraded samples, separate mixtures, and produce profiles to compare to public DNA databases in addition to the regular criminal database (CODIS). Most government crime labs currently do not have this technology. Here are some private labs that might be able to help.
Intermountain Forensics (our lab) has advanced, scientifically validated technology that produces court-admissible DNA profiles. Our Lab Director/Technical Leader and our DNA Analyst are forensic DNA experts who have testified in courts throughout the U.S. The lab generates traditional (STR) profiles, genetic genealogy profiles for public database (GEDmatch) comparison, and Next Generation Sequencing (NGS) that produces sharper profiles from smaller and degraded samples plus "phenotypes" (estimates of the suspect's race, eye and hair color). IMF has interpretation compatible with both STR and NGS profiles, the M-Vac System (confirmed by the FBI to extract up to 12 times the amount of DNA versus conventional methods), the Tissuelyser II for extraction from teeth and bones, and other state-of-the-art technology. IMF offers free 1-hour consultations. After that, the lab's charges are cost+15% for cold cases.
Parabon Nanolabs is a master of using genealogical DNA profiles to identify unknown subjects by comparing the profiles to public DNA databases. It also has proprietary software that produces estimates of an unknown suspect's appearance. (Parabon is not an accredited laboratory and does not testify in court, but it is not required to be in order to provide law enforcement with the names of suspects. After potential identification by Parabon, law enforcement obtains forensic DNA profiles from the subject and then a forensic lab compare them to crime scene DNA.)
Othram is another laboratory that has identified several Jane and John Does and can generate genealogical profiles for purposes of identifying unknown suspects. Othram is not an accredited laboratory and does not testify in court, but is not required to in order to provide information that law enforcement can later confirm through an accredited forensic laboratory.
