This is the earliest case I've found that even mentions forensic genealogy.

One of the affidavits in the case states, quote,

On March 27, 2015, investigator Robert Janes, a retired Seminole County Sheriff's Office Investigator,

utilized the private forensic genealogist service Identifinders International,

and submitted the DNA profile recovered from the hip portion of Pamela's underwear to a forensic genealogist for evaluation.

On that date, the forensic genealogist Dr. Colleen Fitzpatrick and her partners at Identifinders advised the DNA belong to an individual with ancestry from sub-Saharan Africa, where the frequency

of this heritage reaches over 80%. Generally, the presence of this ancestry in the Americas

is primarily due to the transatlantic slave trade." End quote.

Listeners have heard me interviewed Dr. Fitzpatrick before on The Boy in the Box episode.

She's considered the inventor of modern forensic genealogy.

And thanks to identifiers, now the investigators knew that the suspect was likely a black male.

Three decades of looking exclusively at white suspects were for nothing.

In 2017, Detective Jennifer Spears heard about Parabon's

phenotyping service and sent the Reston Virginia Company a sample of the semen from Pam's

underwear. This from Detective Spears' affidavit, quote, they were able to extract 34.83 nanograms of

DNA from the swab with the suspect semen and subsequently sent

that sample to a kisogen for genotyping. The overall genotyping call was 97.4, which indicates that

the sample was from a single source. Parabon nanolab supported the previous evaluation by Identifonders International, that the sample was from a single source. Parabon Nanolab supported the previous evaluation by

Identifonders International that the unknown DNA, developed from Pamela's underwear, belonged to a

male with African heritage with over 80% confidence. Parabon's profile has brown or dark brown

skin color with 95.8% confidence, brown or hazel eye color

with 87.5% confidence, and black hair with 99.99% confidence. End quote. This report from Parabon
