MOSCOW, Idaho – Bryan Kohberger returned to an Idaho courtroom Thursday and said through his attorney that he plans to challenge the evidence against him at a preliminary hearing.

Kohberger, 28, wearing an orange jail-issue jumpsuit, had a slouch in his walk as he entered the Latah County courtroom one week after he was ordered held without bond for the murders of four University of Idaho students.

The 28-year-old criminology Ph.D. student waived his right to a speedy preliminary hearing.

Magistrate Judge Megan Marshall explained to Kohberger that he was only waiving his right to have the hearing within 14 days.

"Do you understand?" she asked.

"Yes," he said, as he leaned forward on his elbows. It was one of several questions he answered from his seat.

Kootenai County Public Defender Anne Taylor reasoned that waiving the 14-day deadline would give her more time to review the evidence obtained through discovery, which she filed a request for on Tuesday, according to court records.

Bill Thompson, the Latah County prosecutor, said he had no objections to pushing back the proceeding.

The judge scheduled the preliminary hearing for June 26 at 9 a.m., which is expected to last five days.

Both sides are expected to call witnesses and present evidence. The judge will decide whether there is enough probable cause for the case to advance to district court.

As part of the June proceedings, the surviving housemate who allegedly witnessed a masked man with "bushy eyebrows" leaving after the murders could testify in court.

Identified in court documents only as 'DM,' she was frozen with fear during the encounter and locked her bedroom door, according to police.

The brief proceeding in front of a packed courtroom lasted less than 10 minutes. Before Kohberger left, he was pictured with several cuts on his face, which the sheriff said came from shaving.

The three young women lived in the home with two other housemates — including one who police say witnessed a masked man with "bushy eyebrows" flee at around 4 a.m. after the killings. Chapin was staying the night.

Kohberger, a Washington State University doctoral student, had been stalking the King Road home for weeks, according to a probable cause affidavit

His cellphone pinged near the house at least 12 times before the murders and once the morning after.

He lived in campus housing in Pullman, Washington, just eight miles from the King Road property.

It took investigators nearly seven weeks to identify and track down Kohberger at his parent's home in Albrightsville, Pennsylvania, where he was arrested Dec. 30.

The accused mass murderer left a Ka-Bar knife sheath next to Mogen's body, which had his DNA on the button snap, the affidavit says.

Several search warrants in Washington and Pennsylvania have also been sealed temporarily. More information is expected to emerge as the case plays out in court.

Kohberger could face the death penalty if convicted on any of the murder charges.
