More chilling revelations about the University of Idaho killings have come to light following the alleged killer's appearance in court on Thursday.

Bryan Kohberger appeared in court in Moscow, Idaho for the first time where the release of his affidavit revealed some horrifying details of the murder of four students, including his alleged final words to his victims before killing them.

As per the Independent, one of the two survivors who had been in the house at the time of the brutal killings overheard the 28-year-old utter the words: "It’s ok, I’m going to help you," before viciously stabbing their friends in their off-site dorm room.

The release of the affidavit was soon followed up by new details about the suspect's alleged past which were revealed by former high school friends.

According to the outlet, friends claimed Kohberger was bullied before becoming a bully himself and allegedly started using heroin.

CBS News also reported that one former classmate knew Kohberger in college at Washington State University, and recalled him being opinionated but otherwise “comfortable around other people.”

"He was very quick to offer his opinion and thoughts," Benjamin Roberts said. "He would describe things in the most complicated, perhaps academic way possible."

He added: "It was like he was trying to convince people that he knew what he was talking about."

It's now been almost two months since the brutal killing of four Idaho university students.

Kaylee Goncalves, 21, Madison Mogen, 21, Xana Kernodle, 20, and Ethan Chapin, 20, were found dead in an off-campus college dorm with horrific stab wounds to the chest.

During a news conference on December 30, Moscow Police Department Chief James Fry said: "These murders have shaken our community and no arrest will ever bring back these young students. However, we do believe justice will be found through the criminal process."

"We developed a clear picture over time,” he said, “(but) be assured that the work is not done.

"This is just started," he added.

At the time of Kohberger's arrest, an attorney acting on behalf of the Goncalves family, Shannon Gray, stated: "Well, I think everybody was relieved, the family was relieved, and, you know, it's long from over. That chapter's kind of closed, at least, and then now the next chapter starts the whole criminal justice process. And so I think everyone had a little bit of relief and was able maybe to sleep at night.

"And then, now it's back to the grind again."

Kohberger was a Ph.D. student studying criminal justice and criminology at Washington State University (WSU) and was arrested at his parents' home in Pennsylvania after being under surveillance by the FBI.

Shortly following his arrest, WSU released a statement revealing that they had cooperated with law enforcement officials in relation to Kohberger's arrest.

"This morning, the Washington State University Police Department assisted Idaho law enforcement officials in the execution of search warrants at Mr. Kohberger's apartment and office, which are both located on the WSU campus," the school said. "WSU Police are working closely with local, state, and federal law enforcement officials as they continue their investigation."

The suspect is currently being held on four counts of first-degree murder and one count of burglary.
