A man linked to a cold case through DNA and genetic genealogy is now in custody, 26 years after allegedly killing a Minneapolis woman, according to local police.

Jeanne Ann Childs, 35, was found dead in the bedroom of her Minneapolis apartment on June 13, 1993, according to police. Authorities declined to say how she was killed.

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.
