Bryan Kohberger went to medical appointment 4 days after Idaho murders, staff remembered him as especially 'charming'

• Bryan Kohberger continued his routine after four Idaho students were killed.
• Kohberger went to a medical appointment, graded school work, and greeted his neighbors.

PULLMAN, Washington — For the man accused of killing four University of Idaho students in November, the rest of the fall semester appeared to be business as usual.

Bryan Kohberger, 28, is accused of fatally stabbing 21-year-olds Madison Mogen and Kaylee Goncalves and the 20-year-olds Ethan Chapin and Xana Kernodle at their off-campus housing in Moscow, Idaho, in the early hours of November 13.

Four days later — when many students in the college town of Pullman, Washington, were canceling their appointments and leaving the community amid fears of a killer on the loose — Kohberger attended a routine medical appointment near his apartment.

A receptionist at the office, who asked Insider not to name her or the business because discussing the interaction might violate medical privacy laws, told Insider that Kohberger was especially friendly at his appointment, prompting the staff to take notice.

Kohberger was so friendly, in fact, her boss commented on it.

"She said, 'He's so nice and charming' — she never says that about anybody," the receptionist told Insider. "I was like, 'Yeah, he really was.'"

At Washington State University, where Kohberger was studying for a doctorate in criminology, he continued working as a teacher's assistant on campus.

On the first floor of Wilson-Short Hall, where Kohberger studied on campus, his photo used to hang in a framed display of criminology students. By Friday, a blank space in the montage with ripped paper inside indicated that his photo had been torn out.

A criminology student named Emilie, who asked to be identified by only her first name, had Kohberger as a T.A. She said he had been gruff and difficult to work with early in the semester.

After the killings, she said, he seemed to lose interest in teaching, assigning his students to write essays and handing back uniform high grades.

"Afterward he didn't grade at all," she said. "He was not a great T.A."

But at his apartment complex, Kohberger remained his normal chatty self, neighbors told Insider.

Kohberger moved into a unit downstairs from Arun Dash, a 28-year-old engineering student at Washington State University, in August and immediately introduced himself.

He would stop and chat with Dash and his roommate, often attempting to make plans to hang out — though their schedules didn't line up.

Even after the killings, when it was on the minds of most people in the Moscow-Pullman community, Kohberger continued to greet them warmly, Dash said.

"Nothing suspicious ever, ever," Dash said.

Kohberger was arrested at his parents' home in Albrightsville, Pennsylvania, on December 30. Prosecutors say they made a biological DNA match from a knife sheath left behind at the scene to his father's DNA in a trash can outside the house.

He's being held without bail on four counts of murder and a charge of burglary. He's expected to appear in court for a pretrial hearing on Thursday.
