FEDERAL WAY, Wash. — A man fatally shot his live-in girlfriend at an apartment south of Seattle then killed three men, including a neighbor who told others to call 911 and retreated inside his unit before the gunman blasted open the door with a shotgun and opened fire, authorities said Monday.
The 28-year-old suspect was later shot and killed in a parking lot by responding officers.
‘‘We believe this is a domestic violence homicide,’’ Federal Way Police Chief Brian Wilson said at a news conference.
Police encountered a chaotic situation in Federal Way on Sunday night when they responded to reports of gunshots. The suspect confronted arriving officers with a shotgun in a stairwell then fled to the parking lot after officers fired at him, Wilson said. He was killed on the ground while reaching for a handgun.
The names of the alleged shooter and the victims have not been released.
However, Wilson said the victims included the suspect’s 25-year-old girlfriend, and three men, including his 62-year-old neighbor. The other men were 24 and 46.
Police were still piecing together information but believe the suspect shot his girlfriend in their apartment then killed the two younger men during an argument after he left the unit.
The relationship between the suspect and those two men wasn’t clear.
