BOSTON (CBS) The highly-specialized technology that police used to create a profile of Vanessa Marcottes killer, could mean the difference between solving a crime and a cold case. <\/p>\n
Marcotte was 27 when she was killed while jogging near her parents Princeton home on August 8, 2016. <\/p>\n
The technology has the potential to show police the killers face and give them desperately needed clues. <\/p>\n
Worcester County District Attorney Joseph Early said Thursday that the person of interest is described as a Hispanic or Latino man with an athletic build, light or medium skin, and shaved or very short hair. <\/p>\n
Scientists at the Parabon NanoLab are able to predict what the suspect looks like by using a small amount of DNA taken from the crime scene. <\/p>\n
Dr. Ellen McRae Greytak, the director of the Virginia lab, explained how the technology works. <\/p>\n
Greytak said, We focus on things that dont change with the environment, so we do pigmentation which is eye, hair, and skin color, as well as freckling. <\/p>\n

She says the lab also focuses on the face and persons ancestry. <\/p>\n
When investigators run out of options, Greytak says they contact her lab, where a majority of these cases become cold cases. <\/p>\n
And what we do is we tell them of those 400 people in the area, you can eliminate 90-95 percent because they dont match this profile, Greytak said. And now you can focus in a manageable number of people. <\/p>\n
From there, the investigators have more information to work with and become more hopeful of solving the case. <\/p>\n
The technology is being used in a Springfield cold case, where investigators say it has helped invigorate interest. <\/p>\n
It is not yet possible to predict height and weight using the technology. <\/p>\n
