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.

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.

Genetic genealogy eyes DNA clues in Nancy Guthrie mystery

Investigators in the Nancy Guthrie case in Tucson are pursuing genetic genealogy to turn DNA evidence into a suspect lead, a method credited with solving the Golden State Killer and other cases; a DNA sample from gloves near her home did not match CODIS, and authorities are also reviewing commercial databases as they analyze additional biological evidence; experts say this approach builds family trees from relatives to identify suspects, though questions about privacy linger.

DNA links deceased man to 1991 Texas yogurt shop murders

The 1991 Yogurt Shop Murders in Austin, Texas, where four teenage girls were brutally killed, have been solved after 34 years using modern DNA and genetic genealogy techniques, leading to the identification of Robert Eugene Brashers as a suspect, who died by suicide in 1999. The case had remained unsolved due to limited evidence and technological constraints, but new methods finally provided closure for the victims' families and the city.

DNA Evidence Solves 50-Year-Old Cold Case, Suspect Arrested

Investigators in Wisconsin have solved a 50-year-old cold case using genetic genealogy, leading to the arrest of 84-year-old Jon Miller for the 1974 murder of Mary K. Schlais, who was killed while hitchhiking to a Chicago art show. This marks the first time the Dunn County Sheriff's Office has used genetic genealogy to solve a case, with assistance from Ramapo College in New Jersey. Miller, who was adopted, confirmed his involvement in the crime and is awaiting extradition to Wisconsin.

"Rock-Collecting Child Discovers Jawbone of U.S. Marine Killed in 1951 Training Accident"

"Rock-Collecting Child Discovers Jawbone of U.S. Marine Killed in 1951 Training Accident"

A jawbone found by a child in Arizona 20 years ago has been identified as belonging to U.S. Marine Capt. Everett Leland Yager, who died in a 1951 training accident. Traditional DNA testing had previously yielded no results, but a genetic profile was developed using genome sequencing and bioinformatics, leading to a match with Yager's daughter's DNA sample. The remains will be returned to Yager's family after being found in the child's rock collection and undergoing extensive forensic investigation.

Long-lost jawbone of U.S. Marine discovered in Arizona child's rock collection

Experts have identified a human jawbone found in a child's rock collection as belonging to U.S. Marine Corps Captain Everett Leland Yager, who died in a 1951 military training exercise. The jawbone, discovered in Arizona, was linked to Yager through genetic genealogy testing performed by college students and a high school intern, making the intern potentially the youngest person to help solve such a case. The bone's presence in Arizona remains a mystery, with one theory suggesting it may have been carried there by a scavenger such as a bird.

"Chewing Gum DNA Leads to Conviction in 1980 Cold Case Murder"

"Chewing Gum DNA Leads to Conviction in 1980 Cold Case Murder"

DNA from a discarded chewing gum led to the arrest and conviction of Robert Plympton for the 1980 murder of Barbara Tucker in Oregon. Tucker, a college student, was kidnapped, sexually assaulted, and beaten to death. Genetic genealogy and a "snapshot phenotype prediction" helped identify Plympton as the suspect. Swabs from Tucker's autopsy and DNA from the gum matched, leading to Plympton's arrest. Witnesses had seen a distressed woman around the time of the murder. Plympton's attorneys intend to appeal his convictions, and his sentencing is scheduled for June.

"DNA Breakthrough Leads to Conviction in 1980 College Student Murder Case"

An Oregon man, Robert Plympton, has been found guilty of the 1980 murder of college student Barbara Mae Tucker after DNA genetic genealogy and a discarded piece of chewing gum linked him to the case. Despite the lack of evidence showing a prior connection between Plympton and Tucker, DNA analysis from the gum matched the DNA profile developed from Tucker's autopsy swabs. Plympton, who pleaded not guilty, was convicted of first-degree murder and second-degree murder charges. He awaits sentencing in June.
