Bryan Christopher Kohberger was an intellectual who was very interested in the way the mind works but was bullied for his weight and awkwardness.

The man was arrested thousands of miles from Idaho and charged with four counts of murder for the deaths of University of Idaho students.

He was a graduate student at Washington State University and lived in Pullman at the time, according to police. He is in a Pennsylvania jail while he waits to be deported to Idaho.

In his home state, he was known as a genius who was socially awkward and had a hard time picking up on social signals, according to a couple of his former classmates.

A criminology student was sentenced to four counts of first-degree murder.

Sarah Healey said he was shy and kept to himself and a small group of friends, but some of their classmates mocked him and threw things at him.

Healey said it was terrible. We didn't know what it was, but there was something off about him. He stopped me in the hallway and asked if I wanted to hang out.

Healey said that they didn't know each other at that point.

She said it was strange. I didn't have a chance to defend Bryan because he would always run away.

The University of Idaho has a timeline about the laughing of four students.

Healey said she was told by other girls in high school that they didn't want to hang out with him.

He didn't get the proper help and it was mostly females that bullied him, according to Healey.

She said that he was very into his books and that his grades were always good.

That continued at Northampton Community College, according to one of the friends who asked to remain anonymous.

He's very smart. A friend of his said that he was a bright kid who stood out in high level classes.

Ryan Christopher Kohler is the murder suspect.

When they heard about the early Friday morning raid on his parents' home in Albrightsville, Pennsylvania, they were shocked.

When she found out that he was in custody, she took a few moments to herself, because she began to tear up.

She said that he was not a violent person.

I would like to speak to him and ask him what happened. Why did it go wrong? What was happening to you? What was going through your head? Why was it happening? Why did this happen?

His friend said that he didn't interact with many people on campus but was friendly with her and they talked for hours about his struggles with heroin addiction and his weight.

The families of Idaho students are protesting the arrest of murder suspect Bryan Kocher.

She hasn't spoken to him in over two years. They had a discussion about what they wanted to do.

She said that he knew he was going for a PhD when he was looking at her master's program.

I didn't know if I would have to do a master's or a PhD program.

I think he was never heard by his peers. It was different when I sat and listened to him and talked with him.

He was always willing to talk to me. We had conversations in the hallways at school or on Messenger for an hour and a half.

The murder suspect's arrest is the first sense of joy in weeks, according to the student's district attorney.

During their talks and classes, she was able to understand him.

She said that he was genuinely curious and thought that he lived a sheltered life, so he asked questions to other people that they thought were offensive.

She said it wasn't intended to be offensive. It was like a genuine curiosity from an adult who you would think wouldn't ask a question. He had no idea about these things. I don't believe he knows better.

A fellow at Washington State's criminology and criminal justice graduate program agreed with those comments.

Ben Roberts told The Tribune Democrat that he had pegged him as being super awkward. Roberts said that he took courses with a man who was always looking for a way to fit in.

Roberts said that he would always find the most complicated way to explain something. He had to make sure you were aware of it.
