Shawn Yim was a Seattle Metro bus driver who was stabbed to death while on the job in Seattle's University District on Dec. 18. Family members say Shawn was a caring, kind person who loved and protected his family.

Initial inconsistencies in Sitzlack’s story led prosecutors to ask for probable cause for domestic violence murder at a court hearing in 2023. Police carried out “numerous search warrants” over months, but there was not enough evidence to disprove Sitzlack’s self-defense argument, McNerthney said. He was never charged in that case.

FOX 13 is now hearing from two of the Metro bus drivers who helped Seattle Police arrest the suspect wanted in connection to the deadly stabbing of Shawn Yim.

Nathan Vass has been a metro driver for 18 years. He's also a writer and filmmaker. He counted Shawn Yim among his friends. He told KUOW’s Rob Wood about Yim’s life and loss, and the role bus drivers play in our city.

Scores of people gathered Saturday night at the intersection where Shawn Yim was killed, overflowing the sidewalk and spilling into the road.
