In Provo, a multi-day preliminary hearing for Tyler Robinson revealed surveillance video, text messages prosecutors say amount to a confession, and a taped interview with Robinson’s former roommate; the defense challenged the DNA and ballistics evidence and questioned investigators’ handling, as prosecutors seek probable cause to move toward trial on charges including aggravated murder and a possible death sentence.
Carla Anderson disappeared from her locked Wadena, Minnesota apartment in 1987, leaving a rented movie in the VCR with no sign of a break-in. Authorities have renewed the case with a $25,000 reward and are using updated technology, including DNA analysis, to pursue both old and new leads as Carla’s family and the small community await answers after almost four decades.
A 26-year cold case from Olympic National Park has been solved: remains found in a sleeping bag in 2000 were identified as Joseph Louis Serrao Jr., who was last seen in 1998, through forensic genealogy and DNA testing conducted by Othram and partners, bringing closure to his Hawaii-based family.
Forensic work and DNA analysis by Othram, using forensic genealogy, identified the skeletal remains found in a sleeping bag in Olympic National Park in 2000 as Joseph Louis Serrao Jr., who had been missing since 1998. Investigators traced relatives across several states and matched DNA to confirm Serrao’s identity, solving a nearly 30-year case and providing closure for his Hawaii-based family; the work was completed by 2025 and publicly announced in 2026.
DNA analysis of Ötzi the Iceman’s 5,300-year-old remains shows ancient fungi and gut bacteria still alive, with cold-adapted species likely colonizing his body and possibly slowly multiplying in tiny pockets of mummy moisture; some microbes are extremely rare in modern industrialized populations, suggesting a distinct Alpine microbiome. The findings highlight microbial longevity in frozen remains and raise considerations for preservation and our understanding of ancient ecosystems.
Alaskan fossils long labeled as mammoth bones were found to be two whale species (minke whale and North Pacific right whale) after radiocarbon dating showed ages of 2,000–3,000 years — far younger than mammoths. Isotopic and DNA testing confirmed cetacean origin and marine diets, and the remains, stored for seven decades in a museum, were likely mislabeled or misattributed since the 1950s. The discovery prompts questions about how coastal whale remains ended up inland and adds to a growing pattern of fossil misidentification.
DNA analysis and a digital facial reconstruction of a 3,500-year-old Mycenaean burial reveal the woman buried beside a man with three swords was his sister, not his wife. The reconstruction shows a young woman; bone and artifact evidence suggest she wielded or owned weapons and endured labor, prompting a rethink of gender roles in Late Bronze Age Mycenae.
At the 100-day mark in Nancy Guthrie’s disappearance, investigators say the case could hinge on a strand of DNA being analyzed by the FBI at Quantico; the DNA was recovered from Guthrie’s Tucson home and initially tested at a private Florida lab before being sent to Quantico, with experts stressing that forensic DNA work— including potential family-tree analyses—takes time. A prior DNA lead from gloves yielded a dead end confirming no connection to the case. Authorities continue pursuing doorbell footage, tips, and digital data, while rewards totaling over $1 million are offered for information leading to Guthrie’s recovery or the arrest of those involved.
South African authorities euthanised a large crocodile and retrieved a Portuguese businessman’s remains from its stomach, confirming the victim as Gabriel Batista, 59, who disappeared after his vehicle was swept away while crossing a partially submerged bridge over the Komati River. The crocodile, about 600 kg and five metres long, was airlifted for examination and its stomach also contained several clothing items; identity was confirmed by DNA analysis as the investigation continues.
Louisiana police arrested four men in the 1982 murder of Roxanne Sharp, aided by new DNA testing and a revived investigation sparked by a podcast; the case, long tracked by former Covington officer Herbie Joiner who died before arrests, underscores persistent collaboration and technological advances in solving cold cases.
Researchers analyzing dust and fibers from the Turin Shroud identified plant DNA—carrot, bread wheat, maize, peanuts, and various fruits—suggesting contamination over time rather than revealing the cloth’s age; metagenomic DNA cannot confirm origin, while radiocarbon dating in 1988 placed the cloth at 1260–1390 AD and a 2024 analysis hinted at a date closer to 2,000 years, with the final results not yet published.
Researchers analyzing dust and fibers from the Shroud of Turin report plant DNA—carrot, bread wheat and other crops—signalling contamination over time rather than confirming the relic’s age; they caution metagenomics can’t reliably date the cloth, even as radiocarbon dating in 1988 placed it medieval (1260–1390 AD) and 2024 WAXS results broadly align with a two-millennium history.
DNA analysis of the Beachy Head Woman, a Roman-era skeleton found near Beachy Head, shows she was likely local to the Roman Britain population, revising earlier guesses of Sub-Saharan African or Mediterranean ancestry; improved DNA techniques also updated her facial reconstruction to reflect light skin, blue eyes, and fair hair, placing her life along the Roman coastal landscape (129–311 AD) and underscoring how genetics can revise archaeological narratives.
DNA testing identified the remains found in a car in the Columbia River as Kenneth, Barbara, and Barbie Martin, the Oregon family missing since 1958. Authorities said there was no evidence of foul play and closed the case, with the car having been recovered from the river years after their disappearance.
DNA analysis confirmed the remains in a car submerged in the Columbia River are Kenneth Martin, Barbara Martin, and their daughter Barbie, the Oregon family who vanished in December 1958; authorities found no evidence of foul play. The Ford wagon was located in 2024 and recovered in following years, with Othram handling the forensic work, and two of the family’s children had been found years earlier while the other members never turned up.
