Andrew Fryberg, the last of the children still in hospital after being wounded in the Marysville-Pilchuck High School shooting, died Friday at Harborview Medical Center in Seattle, Washington.  Freyberg had been fighting for his life for the last 15 days, after being shot in the head.

A total of five people were killed in the incident, when Andrew’s cousin Jaylen Fryberg shot his friends in the school's cafeteria, then shot himself.

The 15-year-old Andrew’s girlfriend Zoe Galasso, 14, died in the shooting on Oct. 24, while four others were taken to hospital in nearby Everett, Washington. The 14-year-old victims Gia Soriano and Shaylee Chuckulnaskit, were shot in the head and later died. Only one teenager, Nate Hatch, the 15-year-old cousin of Andrew and Jaylen, recovered from his wounds, reports said.

“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," Andrew’s family said, in a statement Friday, according to NBC News, adding: "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."

Andrew, Nate and Jaylen grew up together in the Tulalip Tribe, one of the largest Native American groups in the U.S, about 30 miles from Seattle, Washington, according to Daily Mail. Jaylen had invited his friends to lunch by texting them and then shot them. Police officials have not yet been able to ascertain a motive for the shooting.
