DNA based suspect composite
CARLSBAD, CA – The Cold Case Investigation Team working on the Jodine Serrin Murder has recently sought the services of Parabon NanoLabs (Parabon), a DNA technology company in Virginia that specializes in DNA phenotyping : the process of predicting physical appearance and ancestry from unidentified DNA evidence. Law enforcement agencies use the company’s Snapshot ™ DNA Phenotyping Service Snapshot) to narrow suspect lists and generate leads in criminal investigations.
Using DNA evidence from this investigation, Snapshot produced trait predictions for the associated person of interest (POI)*. Individual predictions were made for the subject’s ancestry, eye color, hair color, skin color, freckling, and face shape. By combining these attributes of appearance, a Snapshot composite was produced depicting what the POI may have looked like in 2007. Witness information was also used to estimate age and BMI because those factors cannot be determined from DNA. Snapshot predictions provide approximations of appearance, but are not expected to be perfect likenesses of the DNA source from which they are derived.
While the composite is scientifically based representation of what the killer may have looked like in 2007, the most important factors to consider are the listed genetic predictions concerning the POI’s physical characteristics.
If the above Snapshot composite resembles someone from 2007 that knew Jodine, or someone that she knew who was not previously considered a suspect, please contact us.
