- 2:42Modern DNA testing and forensic genetic genealogy help reopen Yolanda Herrera's decades-old murder investigation.
- 5:03Jason Landry disappeared after his crashed car was found abandoned near Luling, Texas.
- 14:04The documentary reports that DNA identified remains found in September as Landry's.
- 22:20The final investigation uses genetic genealogy after earlier DNA database searches produced no match.
A DNA identification can answer who was found without answering every question about what happened. That distinction runs through Merc True Crime's new documentary, "3 Cold Cases That Had Breakthroughs In 2026".
The film opens with Yolanda Herrera's murder and the forensic genetic genealogy work that revived the investigation four decades later. It then turns to Jason Landry, whose abandoned, crashed car prompted extensive searches in Texas. The documentary reports that remains found in September were identified as Landry's through DNA testing. His father, Kent, and private investigator Abel Pena appear in archival footage, keeping the account connected to the people who searched for him.
The final chapter follows a child's murder investigation through years of unsuccessful DNA database searches and the later use of genetic genealogy. These are different kinds of breakthroughs, not interchangeable declarations that every mystery is resolved.
Posted on Sunday, the documentary had drawn about 740 views in its first three hours. It was Merc True Crime's only new upload of the week. Across the channel, weekly views totaled roughly 14,000, while subscribers stayed unchanged.
Older investigations supplied a modest continuing audience: "2 Decades Old Cold Cases SOLVED in 2026" and "Viewer-Requested Cases: Two Unsolved Disappearances" shared the strongest daily momentum among the older uploads. The new film returns to that same central concern: what further investigation can establish after years without an answer.
A 21-year-old Texas State University student who disappeared in December 2020. His car was found crashed and abandoned near Luling, Texas, while he was travelling to his family home.
