When other law enforcement officers arrived, they found one of the suspects dead of a gunshot wound.
The Pierce County deputy who was fatally shot near Spanaway on Monday morning was a Navy veteran and a father to three children, according to the Pierce County Sheriff's Office.
Several shots were fired during the chase, striking McCartney.
He's described as having a large pointy nose and pock marks on right side of face, and was seen wearing a dark hooded sweatshirt and black beanie.
"Heartbroken to report Deputy Daniel McCartney, #484, lost his life overnight while courageously protecting citizens of Pierce Co.", Pierce County Sheriff's Office tweeted.
The suspect, who authorities described as armed and risky, was the subject of manhunt by K9 units in the area of 200th Sreet as the suspect is being actively searched for by K9 units.
Officials say two suspects were involved. The other is being sought.
It was about 11:25 p.m. when deputies were called to a home in the 5100 block of 200th Street East for a burglary at an occupied home.
McCartney is the first police officer killed in the line of duty in the Seattle area since November 30, 2016 when a Tacoma police Officer was fatally shot in response to a domestic-violence call, local media said.
It's unclear if the deputy was able to return fire at the suspects, who were not immediately identified.
The department asked in a Facebook posting that the deputy's family, friends, and the department be kept in people's thoughts and prayers and that media avoid the area because of the ongoing search for the suspect.
