In a significant development in the case of Bryan Kohberger, the man accused of killing four University of Idaho students, a judge has ruled that key DNA evidence will be admissible at trial. This decision is a major setback for the defense, which had sought to challenge the prosecution’s use of genetic genealogy and other forensic techniques to link Kohberger to the crime scene. As the trial date approaches, the ruling strengthens the state’s case and raises the stakes for both sides.
On November 13, 2022, the small college town of Moscow, Idaho, was rocked by the brutal murders of four University of Idaho students: Ethan Chapin, Xana Kernodle, Madison Mogen, and Kaylee Goncalves. The victims were found stabbed to death in their off-campus home, a crime that sent shockwaves across the nation. For weeks, fear gripped the community as authorities searched for a suspect.
Bryan Kohberger, a 30-year-old criminology graduate student at Washington State University—just nine miles from Moscow—was arrested on December 30, 2022, in Pennsylvania. He was charged with four counts of first-degree murder and one count of felony burglary. Prosecutors later announced they would seek the death penalty.
One of the most critical pieces of evidence in the case is DNA found on a knife sheath recovered at the crime scene. Authorities linked the DNA to Kohberger through Investigative Genetic Genealogy (IGG), a forensic method that uses public genealogy databases to identify potential suspects. The defense, however, argued that the IGG process violated Kohberger’s constitutional rights, claiming law enforcement obtained the DNA data without proper authorization.
The defense also challenged the prosecution’s use of familial DNA, which was collected from trash outside Kohberger’s parents’ home in Pennsylvania. They argued that without a warrant, the collection and testing of this DNA sample should be deemed inadmissible.
On February 19, 2025, Idaho Judge Steven Hippler ruled against the defense, stating that Kohberger had no reasonable expectation of privacy over DNA left at a crime scene. The court determined that the use of IGG and subsequent law enforcement testing were legally valid and did not violate Kohberger’s constitutional rights.
“The DNA found on the knife sheath was abandoned property,” Judge Hippler wrote in his decision. “There is no reasonable expectation of privacy for forensic evidence left at a crime scene.”
This ruling is a crucial victory for the prosecution, as it allows them to present the DNA evidence linking Kohberger to the crime scene. The defense, meanwhile, now faces a tougher challenge in creating doubt about his involvement.
Aside from DNA evidence, prosecutors have presented additional incriminating details, including:
The defense has attempted to suppress various pieces of digital evidence, including data from Kohberger’s phone, search history, and social media activity. They claim that law enforcement exceeded their authority when obtaining these records. However, the court ruled that search warrants for this information were lawfully executed.
Due to widespread media coverage and concerns over securing an impartial jury, Kohberger’s defense team requested a change of venue. The court approved this request, and the trial will now take place in Ada County, Idaho, rather than Latah County, where the murders occurred.
Jury selection is set to begin on July 30, 2025, with the trial scheduled to start on August 11, 2025. Proceedings are expected to last until November 7, 2025.
Given the national interest in the case, Judge Hippler has imposed a gag order, preventing attorneys, law enforcement officials, and other involved parties from making public statements. Additionally, the court has ruled that cameras will not be allowed inside the courtroom during the trial, limiting live media coverage.
These restrictions are designed to ensure a fair trial and prevent potential jury bias. Despite these measures, the case continues to be widely discussed in news outlets and on social media.
For the prosecution, the ability to use DNA evidence is a major advantage. The knife sheath DNA is one of the strongest links between Kohberger and the crime scene. Without it, the case would rely more heavily on circumstantial evidence like cellphone data and surveillance footage.
For the defense, the ruling means they must shift their strategy. They will likely challenge the validity of forensic techniques used and attempt to cast doubt on how the evidence was handled.
The families of the victims have expressed relief over the judge’s decision. Many believe that DNA evidence is crucial in securing justice for their loved ones. The University of Idaho community remains deeply affected by the tragedy, with ongoing support services available for students and staff.
Meanwhile, Kohberger’s family has maintained his innocence. His attorneys argue that the evidence against him is circumstantial and that he deserves a fair trial.
With the trial date approaching, both sides are preparing for an intense legal battle. The prosecution will focus on presenting forensic and digital evidence, while the defense is expected to challenge its credibility and suggest alternative explanations.
If convicted, Kohberger faces the possibility of the death penalty. Given the severity of the charges and the extensive media attention, this case will remain in the national spotlight for months to come.
As the legal process continues, one question remains at the heart of the trial: Will the prosecution’s evidence be enough to convince a jury beyond a reasonable doubt? Only time will tell.
