Here is another report about this case:
Moore’s team used the DNA to “reverse engineer” Lindahl’s family tree.
Parabon loaded the DNA sample from the Maurer crime to a website called GEDmatch and began a form of genetic treasure hunting. GEDMatch is a site where users can upload their genetic testing results, done by companies like 23AndMe and Ancestry.
Typically, Moore said, they find similar DNA from distant cousins of a suspect and build back from there.
“We are looking just for people who are second, third, fourth, fifth cousins and beyond,” Moore said. “Typically we are not getting close matches to close family members.”
Basically, Parabon is “reverse engineering the family tree of the suspect based on who they are sharing DNA with,” Moore said.
Moore said she found multiple distant cousins that led to Lindahl, up to 20 matches and “put those puzzle pieces together.“
It is almost never a single match that leads to an identity. It’s a group of matches to see how they all connect to each other.
“My work, and my team’s work is really about providing answers to these families for years and decades,” Moore said.
