Mirack was found by a colleague on December 21, 1992, when she failed to come to school that day. She had been beaten with a wooden cutting board found near the body and strangled to death; she had also been sexually assaulted.

According to ABC News, the case went unsolved for 25 years until DNA found at the scene was used to create a DNA phenotype, which is a composite of the killer’s physical attributes like hair color, eye color, and skin tone. Prosecutors told ABC News that the DNA lab created visual composites of what the killer would have looked like at various ages and they then uploaded the file to a public genetic genealogy database. It led to matches to relatives of Raymond Rowe.

Investigators later obtained DNA from gum and a water bottle Rowe had used while DJing at a local elementary school. It was a match to the DNA found on Mirack’s body.

Rowe was arrested in June 2018. At the time, Lancaster County District Attorney Craig Stedman said in a statement, ” We know that this defendant raped and brutally murdered Christy Mirack,” Lancaster County District Attorney Craig Stedman said in Monday’s statement. “It is a huge step toward providing long-overdue closure for Christy’s family and friends who have spent decades wondering who brutally murdered their loved one. We really cannot give enough credit to Parabon NanoLabs for the work they did which proved absolutely crucial to filing this charge. Without their work and expertise, quite frankly, we would not be standing here today with the alleged killer of Christy Mirack charged and in custody.”


Rowe Eventually Pleaded Guilty to Mirack’s Murder

In January 2019, Rowe pleaded guilty to first-degree murder, rape and related counts in exchange for life in prison without the possibility of parole, prosecutors told ABC News at the time. There was no motive ever cited by prosecutors, but a minor connection between Rowe and Mirack was found during the trial — she had a pass in her wallet for the Chameleon Club, which is where Rowe worked as “DJ Freez” at the time of her murder.

“We are not at a point where we are discussing or speculating about a motive. Considering the time that has past, some specific questions about motive might never be answered publicly,” District Attorney Stedman said in a statement (via Crime Watch PA). “I can say, in consideration of all the information and evidence – to include the DNA found at the scene – we know that this defendant raped and brutally murdered Christy Mirack.”

Dateline airs Fridays and Saturdays on NBC.
