Students at Marysville-Pilchuck High School in Washington State returned to classes on Monday, over a week after a 15-year-old student fatally shot three of his friends and wounded two others in the school cafeteria last month.

Officials say the shooter, Jaylen Fryberg, opened fire on his five friends and relatives in a crowded lunchroom on Oct. 24. As a result, Zoe Galasso, 14, died at the scene, Gia Soriano, 14, died the following Sunday and Shaylee Chuckulnaskit, 14, died from severe injuries on Friday. Fryberg's cousin, Andrew Fryberg, 15, is reported to be in critical condition while his cousin Nate Hatch, 14, is in satisfactory condition. Fryberg shot and killed himself at the scene.

On Monday, students returned to the school for a day of assemblies and grief counseling at 10:30 a.m. They were greeted by community members who lined the entrance of the high school and cheered as buses and cars entered the school campus. Alumni and community members also decorated the school fence with flowers, balloons and messages of love.

"It's emotional, for sure," said local resident Deidre Butler, according to Chron. "It's incredible that everybody came together like this. It's still hard to believe that it actually happened right here."

Lunch was held in the gym and a smaller cafeteria as the main cafeteria where the shooting remains closed. The normal class schedule resumed on Tuesday.

Washington Gov. Jay Inslee also declared Nov. 3 as "Red and White Day," urging state residents to wear the school colors to show support and solidity.

"When students and staff walk back into their school, I want them to know that nearly 7 million Washingtonians are standing with them," Inslee wrote in a Facebook post, reports the New York Daily News.

"With the help and support of family, neighbors and friends around the state, they will recover together," he added. Inslee

"I think it's going to be huge for the kids to realize that they're not alone walking this journey, that they have way more support than their small circle," said Tammie Clifford, an alumna of the school.
