A 20-year-old woman was fatally stabbed in Kent on Sunday morning and a suspect was arrested after a lengthy standoff, according to Kent police.

Police were called to the 24600 block of 64th Avenue South at about 7 a.m. and found the injured, unresponsive woman in the hallway of an apartment building, along with another woman. Witnesses told 911 dispatchers that the attacker had fled into a nearby apartment, police said.

Police were able to move the women away from the scene, but the 20-year-old succumbed to her injuries and was pronounced dead, according to police.

The suspect, a 24-year-old Kent resident, refused to come out of the apartment and officers believed he was armed with a firearm. After hours of negotiation, the man ultimately left the apartment after the Valley SWAT team used gas to drive him out. He was taken into custody without further incident, according to police.
