SEATTLE (AP) — Authorities in Seattle are investigating the fatal shooting of a man in the Lake City neighborhood Sunday – the fourth gun homicide in the city in 24 hours. A Seattle police spokesperson said witnesses saw the victim returning to his apartment when a vehicle stopped and people opened fire. The Seattle Times reports that earlier Sunday, shootings in four Seattle neighborhoods left three dead and five injured. The shootings continue an ongoing uptick in gun violence that’s killed or wounded over 200 people in King County this year. Seattle Mayor Jenny Durkan on Monday called the gun violence unacceptable and said the city is moving forward with a multi-prong strategy to address it.
