## Resource

This episode details the resolution of the 1989 cold case murder of Mary Kelly, a beloved 78-year-old woman in Dallas. Although investigators initially found male DNA on a ligature at the scene, the case remained unsolved for decades due to the limitations of forensic technology at the time. The investigation was eventually revitalized through investigative genetic genealogy, which utilized a family tree to identify a suspect living right next door to the victim. Following a surreptitious DNA collection from a discarded beer bottle, authorities arrested David Rojas and linked him definitively to the crime. Despite the defendant's claims of a consensual relationship, a jury convicted him of capital murder under the laws active at the time of the offense. This narrative highlights how advancements in DNA sequencing and non-profit funding can finally provide justice and closure for families of long-unsolved crimes. This episode includes AI-generated content.
