A graduate student at Washington State University was arrested Friday in his home state of Pennsylvania in last month’s killings of four University of Idaho students in their off-campus home – a brutal attack that rattled a small college town, authorities said.
A criminal complaint charging Bryan Kohberger, 28, with four counts of murder in the first degree, as well as felony burglary, was filed Thursday, Latah County Prosecutor Bill Thompson said in a news conference Friday afternoon in Idaho.
Authorities narrowed their focus to Kohberger after tracing his ownership of a white Hyundai Elantra seen in the area of the killings, according to two law enforcement sources briefed on the investigation. Kohberger’s DNA has also been matched to genetic material recovered at the off-campus house where the students were stabbed to death, according to the sources.
Genetic genealogy helped investigators identify the suspect, a source with knowledge of the case said. DNA found in Idaho was taken through a public database to find potential matches for family members, the source said. Once potential family matches were found, subsequent investigative work by law enforcement led to the identification of Kohberger, according to the source.
An FBI surveillance team from the Philadelphia field office had been tracking him for four days in the area where he was arrested, according to the sources.
While he was being watched, investigators from the Moscow Police Department, the Idaho State Police homicide bureau, and the FBI worked with prosecutors to develop sufficient probable cause to obtain the warrant. Once the arrest warrant was issued, the Pennsylvania State Police and the FBI made the arrest.
Moscow Police Department Chief James Fry said at the news conference an Elantra has been located, but investigators are still looking for the knife used in the killings. He didn’t reveal any details about the case, including when the suspect became the focus of the investigation or whether he knew the four students who were killed.
“These murders have shaken our community and no arrest will ever bring back these young students,” Fry said. “However, we do believe justice will be found through the criminal process.”
