e-mails looking for help, as well. these investigations that we re working on, sometimes they ve been cold for decades. in these cold cases, they re cold because there are no leads. and in a lot of cases that s because there s no witness description, and we re able to give them that just with the dna. from a single dna sample, parabon can make an estimation of someone s hair-color, eye-color and complexion. we hired parabon to test a sample of my dna. but we didn t tell them it was from me until this interview. i sent in my dna as a blind that was yours. that was mine, as a blind sample. you did not know whose dna we were sending in. no. we did not. parabon built a profile of me as if i were a random criminal suspect. so all we received was a dna vial labeled tr19411, and so these are the predictions that we produced just from that dna. this actually was a pretty interesting eye color prediction, one we don t see
previously, parabon created an image from my dna to show how it works. why am i anxious right now? like, i feel like i am the criminal or something? [laughs] let s see it. all right, okay. oh, wow. i felt like after i got my composite sketch from parabon, but if i had committed a crime and left my dna, i would ve been completely busted. absolutely, you would have been at the top of the suspect list. and now, the lancaster dm is hoping company can help with christie s case. they analyzed the dna left by her killer, trait by trait. hair and eye color, facial structure, even ancestry. we found that he was partially of european descent but, also partially of latino descent, he is a mix of those two ancestry s. they came up with three composite to reflect how he might have aged over the years. he could look a lot like this. right. this might have approximately been what he looked like when the crime was
dna from a crime scene to a database used by thousands looking for lost relatives. their search turned people up whose dna had distant matches to the killer. from there, investigators constructed a family tree, and narrowed it down to their man. when you read about it and see it, you say to yourself, why did i not think about this? i mean, it is completely brilliant. parabon s genetic geologists to the same thing in the hunt for the man who murdered christy. sure enough, they found relatives who shared dna with her killer. in a couple of days, they were able to take these few people, who shared dna with our unknown killer, and build up to that person could have been. remember, they knew the killer had european and latino ancestry. one man in the family tree stood out. he matched the ancestry, and lived near christy when she was murdered. but that didn t mean
It’s a major tool used in law enforcement investigations: DNA, the genetic data collected at crime scenes. It can lead to a suspect or identify a victim, when it’s matched to DNA in a database. But what if there are no matches? Companies have found new ways to use DNA to paint a picture of a person.
