Police believe the suspect was not known to Childs.

We all hope Jeanne’s family can finally find peace.

Through DNA left behind at the crime scene, genetic genealogy was used to investigate and eventually identify the suspect, the Minneapolis Police Department said in a Tuesday statement.

Spokesmen for the Minneapolis police and the FBI declined to specify where DNA was left at the crime scene, how the suspect’s family tree was investigated and how his DNA was obtained.

The novel investigative technique of genetic genealogy takes an unknown killer's DNA from a crime scene and identifies the suspect through his or her family members, who voluntarily submit their DNA to genealogy databases.

The first major public arrest through genetic genealogy was the April 2018 arrest of the suspected "Golden State Killer." Since then, genetic genealogy has helped identify more than 20 other suspects.
