Twin brother arrested after teen stabbed to death in Grant County

A 17-year-old boy is dead and his twin brother is in custody after an early morning stabbing in Coulee City.
Deputies with the Grant County Sheriff’s Office responded to a home in the 300 block of West Washington Street around 2:30 a.m.
The stabbing victim was transported to a local hospital and pronounced dead, Kyle Foreman, spokesman for the Sheriff’s Office, said.
The teen had a single stab wound to the chest.
After interviewing witnesses, the teen’s twin brother was arrested for investigation of manslaughter and assault-domestic violence, Foreman said.
Foreman says the twin brothers got into some sort of argument and that’s when one of them was stabbed.
The brothers attended Smokiam Alternative School in Soap Lake, a small town just south of Coulee City. The victim’s twin brother is being held at a juvenile detention center in Ephrata.
No one has been charged. It is unclear if the teen’s parent’s or other adults were home at the time.
Detectives are investigating and gathering additional evidence. There is no threat to the public.
The names of the twins were withheld because they are juveniles. An autopsy will be scheduled by Grant County Coroner Craig Morrison.
Coulee City, a town of about 600 people, is about 95 miles west of Spokane. No additional information is expected to be available until Tuesday, Foreman says.
