A teenage boy named Jaylen Fryberg opened fire in his high school cafeteria Friday.
Though police refused to name Fryberg, both witnesses and multiple media agencies identified him as the shooter.
The shooting happened at Marysville-Pilchuck High School, about 37 miles north of Seattle, where Fryberg was a freshman.
Fellow freshman Brandon Carr spoke with The Seattle Times about the shooting. Carr said he "started hearing these loud banging noises, like someone hitting a trash can," heard screaming, and ran.
“Once I knew it was gunshots, we just booked it,” Carr told the paper.
Students at the school hid under classroom desks and in closets, among other places, as the school was placed on lockdown.
As of Nov. 7, a total of five people had died from the shooting, including Fryberg.
Zoe Galasso died at the scene. Her funeral was held Oct. 30. Gia Soriano died from her injuries on Oct. 26, at which time her family released a statement:
We are devastated by this senseless tragedy. Gia is our beautiful daughter and words cannot express how much we will miss her. We've made the decision to donate Gia's organs so that others may benefit. Our daughter was loving, kind and this gift honors her life.
Thank you to Providence for their excellent care – bar none – from beginning to end. Thank you to our friends and family who have supported us. Thank you to Drs. Bill Finley, Sanford Wright and Anita Tsen for their tremendous support and compassion. And thank you, to Bill and Ben with LifeCenter.
We ask that you please respect our privacy and give us the space and time we need to grieve and spend time together as a family in memory of Gia.
Shaylee Chuckulnaskit died Oct. 31. Her family also released a statement:
Our hearts are broken at the passing of our beautiful daughter. Shay means everything to us. In Shay's short life she has been a radiant light bringing us incredible joy and happiness. She has been a loving daughter, a caring sister, a devoted friend and a wonderful part of our community. We can't imagine life without her.
We have been overwhelmed by the thoughtfulness and support of our family, friends and community. We are deeply grateful for all the acts of kindness that have come our way. We especially want to thank the medics and Providence staff who have cared for Shay.
We request that everyone please provide us the privacy we need so we can grieve our loss. Thank you.
On Nov. 7, 15-year-old Andrew Fryberg died from his injuries. His family released a statement:
We express our thanks for the amazing support from the community, as well as from everyone around the world that have been praying for us all through this tragic event.
We also want to say a special thank you to all the amazing staff that have cared for our son and brother here in the pediatric intensive care unit at Harborview.
Our family is overwhelmed with the love and care that has been provided to our loved one during this time and you all will forever hold a special place in our hearts.
But we also ask that you respect our privacy at this time of our deep loss.
Following Andrew Fryberg's death, 14-year-old Nate Hatch became the only surviving victim. Both he and Andrew Fryberg reportedly were Jaylen Fryberg's cousins.
Fryberg's motive remained unclear, though clues about his recent life suggest he experienced things ranging from relationship woes to trouble at school.
A student at the school told The Seattle Times that Fryberg was angry about a girl. The student added that the girl was one of those shot. Fryberg's recent tweets also include complaints about feeling broken.
"He shot people he cared about," Dylen Boomer, a friend and football teammate of Fryberg's, told the Seattle Times.
Fryberg also recently had been suspended after getting into a fight, CNN reported. A student said the incident involved bullying and "a couple words said towards him that he obviously didn't like."
Still, Fryberg reportedly was popular at his school and recently was crowned a homecoming prince.
The freshman also was a student athlete and played on the school football team. A student told The Seattle Times that Fryberg was in good spirits at practice on Thursday.
According to Fryberg's social media pages, he was an active hunter, posting numerous photos of himself posing with wild game.
Over the summer, he was given a hunting rifle for his birthday. A law enforcement official told CBS News, however, that they believe Fryberg used a Beretta 40-caliber handgun during Friday's shooting.
Fryberg was also a member of the Tulalip Tribe. His grandfather is the director of fish and wildlife for the tribe.
His Twitter account is troubling. It's mostly a mix of pornography and angry tweets alluding to the fact he recently broke up with his girlfriend.

His last tweet was posted Thursday morning.
It won't last.... It'll never last....
Friends and classmates of Fryberg's mourned his death on social media Friday.
RIP Jaylen Fryberg. The news didn't know who you really were.
