In August of 2019, Detective Decker made arrangements to transfer the SNIP profile Parabond had used for the phenotype to Dr. Fitzpatrick at Identifinders International and requested that her team perform an IGG analysis.

The upload to Jedmatch took place on August 8, 2019. There, the genealogists found the top match shared 141 centumorgans with Sarah's killer.

A second good match shared 82 centumorgans of DNA with the suspect.

These matches had last names Cockrell and Applegate, but the most common name in the family

tree was Campbell. Spoiler, the suspect's last name was none of those.

Identifieders'alogist Gretchen Stack and Holly Turk started building family trees,

using the top two matches and lower-level matches. Things were complicated because they came

to believe the top match's father was the result of an NPE, a non-paternity event, meaning that the

father he had in his family tree was not consistent with the DNA matches. They had to conduct an

adoption search to identify the biodad. It turned out the connection to the killer was on this

top match's maternal side, so the unknown father was irrelevant. But of course, until the genealogists

built out the trees for the top two matches and lower matches and figured out where they all

intersected, they had no idea what the relationships were. Once they built out all the trees,

the genealogists focused on two brothers who fit the bill. They were second cousins to the

top match along their maternal line,

sharing great-grandparents, and fourth cousins to the second top match along their paternal line,

sharing great-great-great-grandparents. The genealogists were able to identify three sets of

grandparents of these brothers. The fourth grandfather was believed to be adopted, his biological

father's name, unknown.

On September 26, 2019, identifiers provided the names of these two brothers to Detective Becker.

The brothers were equally viable suspects. They both lived in the area. Both brothers had dirty blonde hair and blue eyes, and neither was ever mentioned in the case file.

The older brother was a registered sex offender with a conviction for first-degree rape.
