Following closely on the news of the arrest of alleged Golden State Killer Joseph James DeAngelo based on the use of a genetic genealogy database, police in Pennsylvania have made an arrest in the 1992 rape and murder of Christy Mirack, an elementary school teacher in Lancaster.

The Washington Post reports that the arrest of Raymond Rowe — a “49-year-old, a popular wedding and event DJ in central Pennsylvania who goes by DJ Freez” — was determined to have a genealogical connection to the unidentified suspect.

Upon learning of Rowe’s potential connection to the scene, investigators surreptitiously collected samples of his DNA, which was quickly matched to DNA (semen) left at the crime scene.

According to the district attorney’s office, there is a 1 in 200 octillion chance the match is to another member of the Caucasian population who is not Rowe.
