A Washington state sheriff's deputy has died and another remains on life support after they were ambushed while responding to a domestic violence call that turned deadly, authorities said Wednesday.

Spokane County Sheriff's Office deputies responded to a home Tuesday after a woman ran to a neighbor's house reporting that her brother had shot her, two wounded deputies to safety. Both deputies were rushed to a hospital along with the initial female victim who was treated for injuries that were not life-threatening.

Inside the home, investigators found one person dead, while another body was found in the yard. The suspect was also found dead on the property. Authorities have not released the identities of those who died.

On Wednesday, the sheriff's office confirmed that one of the wounded deputies succumbed to his injuries. He is survived by his wife and two children.

"Although we know our deputies knew the risks, they bravely moved toward danger to protect others they did not know," the sheriff's office said in a statement. 

"They did this with honor and with an unwavering sense of duty to their oath to serve and protect the citizens of Spokane County; they heroically placed themselves in mortal danger."

The second deputy remains on life support but is not expected to survive, according to officials.

"As an organ donor, arrangements are being made, and he will continue to serve others with the gift of life," the agency added.
