DNA Breakthrough Solves 1994 Koblenz Murder of American Tourist Amy Lopez

German police arrested an 81-year-old man in Koblenz for the 1994 murder and sexual assault of American student Amy Lopez after advances in DNA technology and re-examining evidence led to a match between a saliva sample and DNA found in Lopez's jeans. The suspect had a prior 1999 conviction for attempted rape; his genetic data, once deleted, was re-accessed to secure the arrest, and he is now in pretrial detention as investigators continue the case decades after the crime.

DNA at Guthrie home may offer limited clues, sources say

DNA at Guthrie home may offer limited clues, sources say

DNA recovered from Nancy Guthrie's Tucson home is described as low-level and may not yield a clean, usable profile for comparison in FBI or private databases; investigators say enhancement is possible but could take longer. A Florida lab is analyzing the samples as the case remains unresolved, with no suspects named. A DNA profile from gloves found near the home did not match the FBI’s CODIS. Authorities are turning to genetic genealogy via GEDmatch Pro and FamilyTreeDNA, both using opt-in consent. Rewards total up to $1 million for information, in addition to a $100,000 FBI reward.

Cave-borne cheetah DNA reshapes Arabia’s conservation blueprint

Saudi researchers found seven naturally mummified cheetahs in five caves near Arar, with DNA from three mummies showing two of the oldest specimens belonged to Acinonyx jubatus hecki (Northwest African cheetah). Dated up to 4,000 years old (and up to ~1,870 years for some), the remains reveal multiple cheetah lineages once roamed the Arabian Peninsula and indicate cheetahs thrived there historically. The study, based on exceptionally preserved tissue, offers a DNA-backed guide for selecting subspecies and lineages best suited to potential reintroduction in Saudi Arabia’s protected habitats.

New evidence surfaces in Nancy Guthrie kidnapping probe

Three weeks after Nancy Guthrie vanished from her Tucson home, CNN outlines a visual guide to the evidence: surveillance footage shows a masked man at the door attempting to block Guthrie’s Nest camera, investigators recovered a backpack and gloves, DNA found on Guthrie’s property has no matches in CODIS, and ransom notes are being scrutinized with genetic genealogy as a potential next step. A private donor has added a $100,000 reward and authorities have boosted the reward to $100,000, bringing total offers to $200,000 as investigators pursue tips and leads.

DNA Clues and Surveillance Footage Shape Ongoing Nancy Guthrie Disappearance Case

The 84-year-old Nancy Guthrie remains missing 19 days after her Feb. 1 abduction near Tucson. Authorities say gloves found about two miles from her home contained DNA from an unknown man and appeared to match a masked suspect seen on her doorbell footage; the Pima County Sheriff has cleared all Guthrie family members as suspects. Investigators have conducted searches including a nearby private residence and a Culver’s parking lot, and a ransom note has fueled public speculation that officials warn against. Savannah Guthrie and her siblings have publicly pleaded for her return, highlighting how true-crime attention and social media chatter are impacting the investigation.

DNA on Glove in Guthrie Family Case Yields No CODIS Hit, Investigators Weigh Genetic Genealogy

DNA found on a glove near Nancy Guthrie’s home did not match CODIS, and authorities have not identified suspects or persons of interest. The case remains open as investigators continue analyzing DNA from the residence and consider using Investigative Genetic Genealogy to help identify a potential suspect or lead, with officials saying the perpetrator appeared to have had a targeted motive.

DNA Glove Yields No CODIS Hit as Guthrie Case Refocuses on Home DNA

Investigators probing the disappearance of Nancy Guthrie (Savannah Guthrie’s mother) report no CODIS match from DNA found on a glove discovered near the home, while DNA at the residence remains under analysis. Surveillance footage showed a masked man, and authorities say the case may be targeted, prompting a potential shift to investigative genetic genealogy (IGG) if CODIS yields nothing. The FBI and sheriff’s investigators continue to work leads and have not named any suspects.}

DNA Clue Drives FBI Probe in Nancy Guthrie Disappearance

The FBI says a recovered glove with a male DNA profile appears to match gloves seen in surveillance footage outside Nancy Guthrie’s Tucson home, fueling a DNA-based lead as the search enters its third week. Authorities have increased the reward to $100,000 and are awaiting private-lab DNA results, with NBC reporting investigators are moving away from Guthrie relatives as suspects. Savannah Guthrie posted a hopeful video marking two weeks since her mother’s disappearance, while investigators continue to pursue surveillance footage and other leads.

DNA Clues Keep Guthrie Case Active as Public Tips Roll In

Two weeks after Nancy Guthrie vanished near Tucson, investigators have not arrested anyone; DNA found on her property does not belong to someone in close contact with her, and gloves found nearby are being tested against a masked suspect seen on her doorbell camera. A late-night search of a nearby home and a Culver’s parking lot yielded no arrests as the FBI tallies thousands of tips and has raised the reward to $100,000, while Guthrie’s family publicly pleads for information.

Identical DNA, Indistinguishable Suspects in Paris-Area Double-Murder Trial

Two identical 33-year-old twins are among five defendants on trial near Paris for a 2020 double murder and subsequent attacks. The DNA on an assault rifle cannot distinguish which twin fired, forcing investigators to rely on phone records, surveillance footage and other evidence while the crucial shooter remains unidentified, with a verdict expected in late February.

AlphaGenome: DeepMind’s AI Maps the Genome’s Hidden Rules

DeepMind’s AlphaGenome trains an AI on vast molecular data to forecast how mutations and regulatory DNA elements alter gene activity, extending the AlphaFold-era breakthrough from proteins to the genome; experts see it as a major engineering advance with potential for cancer and disease research, but stress it remains a predictive tool—its scope is limited to single mutations in a given genome, its predictions don’t capture all splice-site complexities, and clinical use still requires lab validation.

DNA, Mud and a Cold Case: Beaverton Murder Ends with Husband's 2025 Conviction

Decades after Debe Atrops was murdered in Beaverton, Oregon, a 2022 cold-case review used DNA testing on Debe’s coat and soil/mud analysis to reexamine suspects, including her estranged husband Bob Atrops. A 2025 grand jury indicted Bob, and a jury convicted him of second-degree murder after weighing evolving forensic evidence and disputed alibi details; prosecutors say the case involved motive, means, and opportunity, while the defense pointed to other explanations and questioned the strength of the DNA and mud links. Debe’s daughter and family describe the verdict as closure after a long, painful saga.

DNA ties 2006 Oregon mayor to Washington beach remains, ending cold case

Skeletal remains found in 2006 on a Quinault Nation beach in Grays Harbor County, Washington, have been identified as Edwin Asher, a former Fossil, Oregon mayor who disappeared in 2006 during a crabbing trip and was presumed drowned. The identity was confirmed by Othram through DNA analysis and investigative genetic genealogy, closing a decades-long mystery surrounding his disappearance.
