The man accused of the brutal murders of four University of Idaho students is facing an April deadline to provide an alibi.

Madison Mogen, Xana Kernodle, Kaylee Goncalves, and Ethan Chapin were killed inside the house they rented near the campus in Nov. 2022.

Bryan Kohberger was arrested at his parents' Pennsylvania home the following month as the prime suspect in the killing.

Bryan Kohberger Alibi

His defense team claimed he had an alibi for the time of the killing but has not provided it.

Prosecutors requested more information from Kohberger's legal team last month about the alleged alibi.

The judge set a deadline of April 17 for the defense to provide documents relating to an alibi, Newsweek reported.

A hearing that day will only focus on Kohberger's possible alibi defense.

Another hearing in May will be held on a request to move the trial and a trial date.

The Idaho Supreme Court last week rejected his appeal of a grand jury indictment over the murders. Kohberger's defense claimed the grand jury was biased against him because of publicity surrounding the sensational murders.

The victims were found to have been stabbed to death on Nov. 13, 2022, and two others, Dylan Mortensen and Bethany Funke, were at the home at the time but were not harmed. Investigators early in the probe quickly ruled out the surviving roommates as suspects.

Initially, officials believed that Mortensen and Funke slept through the attack that killed the four victims. However, the probable cause affidavit, which was released in January last year after Kohberger came back to Idaho, revealed that one of them said they saw the killer.

The roommate described a "figure clad in black clothing and a mask" who she said walked past her as he left the crime scene. She also said that on the night of the killings, she heard crying.

The judge in the case entered a not guilty plea on Kohberger's behalf in the case.
