Seattle Mayor Katie Wilson asked embattled Police Chief Shon Barnes to resign Wednesday, bringing a dramatic end to a tenure that unraveled over the course of just four days following the deadly Bite of Seattle mass shooting. Bite of Seattle shooting becomes defining momentThree people were killed, and several others were wounded Sunday evening after gunfire erupted near the Seattle Center Armory as thousands attended the annual Bite of Seattle festival. By KOMO’s calculation, those trips and other absences amounted to nearly 50 days away from his Seattle office. Barnes’ office said he personally paid for his Chicago travel while the city funded conference-related travel, although conference organizers sometimes covered part of those costs. Barnes attended a vigil honoring the victims of the Bite of Seattle shooting but departed before the program began.
