The owner of a Pennsylvania brewery said that the suspect in the killings of four University of Idaho students had made inappropriate comments to some employees.

The arrest of Bryan Christopher Kohberger in Albrightsville, Pennsylvania, on a murder warrant in the deaths of the students in Moscow, Idaho, has made some people reflect on their interactions with him.

Jordan Serulneck said that he had gone by himself to the brewery a few times and sat at the bar.

The suspect may have been a student at DeSales University, which is less than 6 miles south of Bethlehem. He received a bachelor's degree from DeSales in 2020 and a graduate degree in June of 2022.

The brewery had unusual characters, but they were not out of the ordinary, Serulneck said.

He said that if only one person was working at the bar, he would make comments under his breath.

There were notes added to the bar's system when he was scanned.

The staff told them to keep an eye on him. He will have two or three beers and get too comfortable.

The female staff at the brewery would be asked where they lived and what their work schedule was. He said that if the women blew him off, he would get upset with them and call one of his staff members a derogatory term.

The owner said that he hadn't been back to the brewery since Serulneck approached him about the complaints from his staff.

I told Bryan to come back. He said that he wanted to talk to you quickly so that he wouldn't have any issues with you. He was completely shocked. He said, 'I don't know what you're talking about'. You don't know what to think.

He said that the man had one beer.

'I'm still worried about this'

Knowing that the suspect is accused in the Idaho killings has left people uneasy.

The suspect's neighbor in a student housing complex in Pullman, Washington, said that he helped remove snow from his car window after a snowstorm in December.

She said that her husband saw that he needed help.

The mother of two said she was scared to live near an alleged killer after seeing him in media reports.

He said that it was not safe to live here. I don't want to leave the house. I worry about this.

The Washington State University student who took four courses with the PhD student continued to attend classes through the end of the semester.

Norton said that Bryan did not contribute to the discussion of the murders. When the murders took place, we were released from class early to get home, and Bryan was in those classes with us.

Austin Morrison, a criminal justice major at Washington State, said that he had a teaching assistant in his class who graded his papers and gave feedback on how to write case briefings.

Morrison said that he was quiet and sat off to the side.

Morrison advised to let the judicial system play out before making a decision.

Morrison said that he was in the mindset that he was innocent until proven guilty. I have a stance on it.
