More information has been uncovered about the student responsible for a fatal shooting at Marysville-Pilchuck High School in Washington State on Friday.

The shooter has been identified as 14-year-old Jaylen Fryberg, a popular student at the school, which is about 40 miles north of Seattle, according to a government official with knowledge of the shooting, reports The Associated Press.

Not only was Fryberg a well-liked athlete who played on the school football team, but he was also named the Freshman Class Homecoming Prince just one week ago.

Video from the school's Oct. 17 football game shows the teen dressed up in a tie and vest at the royal court ceremony while his peers cheered him on.

One of his friends and schoolmates, Nate Heckendorf, explained that this honor means "a lot of people had good hopes for him and thought the best of him," reports CNN.

"That (title) means ... teachers like you. Your peers like you," freshmen Rachel Heichel said. "You're a person that everyone likes and a good person." She added that all of those characteristics applied to Fryberg.

From the looks of his Twitter account, Fryberg appeared to be an avid outdoorsman who loved hunting and took pride in his Native American heritage.

However, some recent tweets hinted that he wasn't entirely happy with everything in his life.

"It breaks me... It actually does.... I know it seems like I'm sweating it off... But I'm not.. And I never will be able to," he tweeted earlier this month. There are also reports that he and his girlfriend recently broke up.

He posted his final tweet on Thursday, which read, "It won't last.... It'll never last...."

A classmate named Jordan Luton added that Fryberg got into a fight with someone who "said something racist to him" a few weeks ago. According to a federal law enforcement source, he had been suspended after the fight.

Still, Fryberg's friends and peers say that the incident has taken them completely off guard.

Luton said he spoke with Fryberg at football practice one day prior to the shooting, "and he was all fine."

"Nobody would have expected it from him," he said.

Heichel said she was in the cafeteria when the teen opened fire.

"When I saw him, I was like, 'Oh my God, that's Jaylen,'" she said. "I would have never expected it would have been him, out of all people. It was really heartbreaking for me to see that."

What makes this incident even more shocking is the fact that two of the people wounded in the shooting were the shooter's own cousins.

Fourteen-year-old Nate Hatch and 15-year-old Andrew Fryberg are related to the shooter, according to Hatch's grandfather, Donald Hatch.

"My grandson and the shooter were best friends," the boy's grandfather said, according to ABC News. "They grew up together and did everything together.
