MARYSVILLE, Wash. — A 14-year-old girl who was wounded when a student opened fire inside a Washington state high school has died, raising the death toll in the shooting to three.

Gia Soriano died Sunday night, more than two days after she was shot, officials at Providence Regional Medical Center Everett said.

“We are devastated by this senseless tragedy,” her family said in a statement, read at a news conference by Dr. Joanne Roberts. “Gia is our beautiful daughter, and words cannot express how much we will miss her.”

Roberts said Gia’s family was donating her organs for transplant.

Another girl was killed Friday when a popular freshman at Marysville-Pilchuck High School north of Seattle opened fire.
