Andrew had been on life support for two weeks at Harborview Medical Center in Seattle. He was the fourth victim to die since the Oct. 24 shooting.

His death was announced just after 9 p.m. in a news release from the hospital that included this statement from his family:

“We express our thanks for the amazing support from the community, as well as from everyone around the world that (has) 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.”

Nate Hatch, 14, is the only survivor of that day’s violence inside the high school’s main cafeteria. He came home from Harborview Thursday as about 200 people lined the main street heading to the Tulalip reservation where he lives.

Also killed were Shaylee Adelle Chuckulnaskit, Zoe Raine Galasso and Gia Christine Soriano, all 14.  Shaylee was expected to be buried Friday. Zoe’s memorial was last week. Gia’s service is scheduled for Nov. 15 in Everett.

Andrew and Nate were cousins of the 15-year-old shooter, who took his own life.
