Sheriff Wyckoff suffered a fatal heart attack after his jail was invaded by an angry mob who lynched several prisoners for a murder the previous day. The citizens held down Sheriff Wyckoff and his deputies as they took the prisoners to nearby gallows. After hanging the first two prisoners they returned to the jail to get the inmate being held for the murder of Seattle Police Officer David Sires the previous year. The men also took this suspect and hanged. Shortly afterwards Sheriff Wyckoff suffered a fatal heart attack.
Sheriff Wyckoff had served as Sheriff for 19 years and was survived by his wife and son.
