Jaylen Fryberg was identified by a government official as the 14-year-old high school shooter at Marysville-Pilchuck High School, just north of Seattle in Washington State Friday. Jaylen Fryberg, a popular freshman, reportedly opened fire 10:39 a.m. at the school's cafeteria, killing one classmate and wounding four others.

According to students of the Washington State high school, Jaylen Fryberg had recently been suspended from the Marysville-Pilchuk football team after getting into a fight over "racist" comments. Others say him getting rejected by a girl could have been reason for the attack.

Earlier this month, Jaylen Fryberg was crowned homecoming prince. However, one of his classmates told CNN the title may have been subject to bullying.

15-year-old Jarron Webb reportedly told the Seattle Times Jaylen Fryberg was angry after a girl rejected his advance. He said Fryberg killed her as payback for spurning him.

Meanwhile, the teen's friends and classmates called him a nice, well-liked boy. However, his posts portray a different side to the troubled teenager.

Days before the Marysville shooting rampage, high school shooter Jaylen Fryberg posted a cryptic tweet.

"Alright. You f***ing got me.... That broke me," said the 14-year-old.

"Your gonna piss me off... And then some s*** gonna go down and I don't think you'll like it..." he also tweeted recently.

In other messages, the high school freshman also expressed his desire to kill himself.

"F*** it!! Might As Well Die Now," Jaylen Fryberg tweeted in June.

The last ominous post from Fryberg's alleged Twitter account was posted Oct. 23.

Hours after the tweet, while inside the school's crowded cafeteria, Jaylen Fryberg rose from a table, pulled out a handgun - believed to be a .40-caliber Beretta - and walked up behind one table opening fire, according to published reports.

The high school shooter reportedly committed the attack without uttering a single word. Soon after the shooting, terrified teenagers started running out of the building towards safety. Others were remained inside their classrooms.

According to Brian Patrick, his daughter, also a freshman, was 10 feet away from Jaylen Fryberg as the Marysville school shooting took place. She called her mother soon as she got away from the scene.

"The guy walked into the cafeteria, pulled out a gun and started shooting. No arguing, no yelling," Patrick's daughter told him.

The WA high school shooter "was just staring down every one of his victims as he shot them," said another student.

Parents waited in a parking lot in a nearby church, according to the Associated Press.

"I thought, 'God let my kids be safe," said Patrick after the Marysville school shooting, who has another daughter who is a senior at the school.

CNN spoke to a student via phone who described the scene of the shooting as having "blood everywhere."

According to the witness, Jaylen Fryberg's handgun jammed at one point, giving him opportunity to flee the cafeteria. He added that the WA high school shooter remained silent during the shooting rampage.

Five students were hit by Jaylen Fryberg. One is reported to have died at the scene before the young teen turned the gun and killed himself.
Three students remain in critical condition at Providence Hospital after suffering head injuries from the shooting. Two of them were admitted to surgery. Another student with less severe injuries, was reportedly transferred to Seattle's Harborview Medical Center.

One of the victims in critical condition was confirmed as Jaylen Fryberg's cousin, reports KIRO TV.
