Another student who was severely injured during the shooting incident at a local school in Washington on Oct. 24 has died, raising the number of fatalities to four.

Shaylee Chuckulnaskit, 14, passed away on Friday, Oct. 31, at Everette's Providence Regional Medical Center after having been in critical condition since the shooting.

In a statement, as quoted by CBS News, the family said, "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."

Chuckulnaskit's is the fourth young life that has been taken by the shooting that happened at the cafeteria of the Marysville-Pilchuck High School in Marysville, Washington, located 30 miles north of Seattle.  Fourteen-year old Zoe Galasso died at the scene, having suffered a gunshot wound to the head. Gia Soriano, also 14, passed away Sunday, Oct. 26, at the Providence Regional Medical Center.

The gunman, Jaylen Fryberg, who used a .40 caliber Beretta to open-fire at the students in the cafeteria, also died during the incident. According to reports, he shot himself in the head when social studies teacher Megan Silberberger intervened in the shooting. The Snohomish County medical examiner's office ruled suicide as the cause of his death.

Meanwhile, Nate Hatch, 14, was shot in the jaw but is said to be in satisfactory condition, while Andrew Fryberg, 15, is in critical condition. Both teenagers, currently being treated at the Harborview Medical Center in Seattle, are cousins of the gunman.

Marysville-Pilchuck High School has been closed since the shooting. It will open Monday, with grief counselors to be present in the campus to help students cope with the loss and trauma brought about the devastating events.
