On Nov. 13, 2022, Ethan Chapin, 20, Xana Kernodle, 20, Maddie Mogen, 21, and Kaylee Goncalves, 21, were stabbed to death
Authorities say Ethan Chapin, 20, Xana Kernodle, 20, Maddie Mogen, 21, and Kaylee Goncalves, 21, were stabbed to death on the second and third floors of the home where the women lived with two other roommates and where Ethan was staying the night with his girlfriend Xana.
For nearly seven weeks, authorities searched for a suspect while the small Idaho community stayed on high alert — until finally, there was a break in the case.
Here’s everything that has happened in the case one year after the murders that shocked the nation.
Nov. 30, 2023: Vigil Held for Slain Students While Authorities Search for Leads
Loved ones and fellow students gathered at the University of Idaho to remember the four young lives lost while authorities continued the search for a suspect. Ethan's mother Stacy Chapin, Kaylee's father Steve Goncalves and Maddie's father Ben Mogen spoke about their children with hundreds of people in attendance.
Stacy spoke about Ethan's vibrant social life and close relationship with his siblings.
"Make sure you spend as much time as possible with those people, because time is precious, and it's something you can't get back," Stacy said during the vigil.
Steve took the stage with his wife and Kaylee's mother, Kristi Goncalves, standing next to him. He spoke about Kaylee and her best friend Maddie.
"They went to high school together, then they started looking at colleges," Steve said. "They came here together. They eventually get into the same apartment together. And, in the end, they died together. In the same room, in the same bed."
Steve said their friendship had given their family strength since the students' killings. "It's a shame and it hurts, but the beauty of the two always being together comforts us," he said.
Maddie's father Ben spoke about her lively social life, good grades and love of music. He called her "such a great kid and a perfect little baby."
Xana's family could not attend, the dean of students said during the vigil, but he noted that Xana was a member of Pi Beta Phi sorority. In a tribute on the Pi Beta Phi's Instagram page, the sorority called her "a magnet for positive energy [who] always radiated that energy back into the world."
The sorority described Maddie — who was also a member of the chapter — as "passionate about every aspect of her life."
Dec. 30, 2022: Suspect Arrested in Pennsylvania
After news broke of the 28-year-old’s arrest, it was learned that Kohberger was visiting family for the holidays when he was detained, but was residing in Washington State at the time of the murders. He was listed as a PhD student at Washington State University in Pullman, Wash., in the Department of Criminal Justice and Criminology on the school’s website. The university is located eight miles away from the 1122 King Road residence in Moscow, Idaho, where the four students were killed.
Ethan’s family later released a statement about the arrest, saying, "We are relieved this chapter is over because it provides a form of closure ... However, it doesn't alter the outcome or alleviate the pain. We miss Ethan, and our family is forever changed."
On Jan. 4, Kohberger was transported to Idaho.
Jan. 5., 2023: Bryan Kohberger Is Charged; Probable Cause Affidavit Released
Kohberger was charged with four counts of murder and one count of felony burglary in connection with the stabbing deaths of Ethan, Xana, Maddie and Kaylee.
The probable cause affidavit was also released, providing more information on the killings and the two surviving roommates who were in the house at the time of the attack.
According to the affidavit — which was previously reviewed by PEOPLE — a sheath of the knife used in the stabbings was left at the scene in the bed where Maddie and Kaylee were found deceased. On the sheath, detectives allegedly found DNA linking Kohberger to the murders and also used his cell phone pings, the affidavit states.
One of the surviving roommates also said they saw the killer, described in the affidavit as "a figure clad in black clothing and a mask," who walked past her as he left the crime scene.
At around 4:20 a.m., a white sedan referred to as "Suspect Vehicle 1" in the affidavit was seen leaving the area of the home at a high speed, the affidavit alleges. According to the document, the vehicle and phone associated with Kohberger returned to the scene between 9:12 a.m. and 9:21 a.m. that same day.
Feb. 24, 2023: University Announces House Will be Demolished
In a February 24 statement on the school's website, University of Idaho President Scott Green said that the school had acquired the home where the murders took place.

Demolition also removes efforts to further sensationalize the crime scene. We are evaluating options where students may be involved in the future development of the property."
