Washington State's death penalty chamber has officially closed and will be preserved as a historical site.

Washington State's death penalty chamber, active from 1904 to 2010 with 78 executions, has officially closed and will be preserved as a historical site. The last execution occurred on September 10, 2010. The state abolished the death penalty in 2018, joining 23 others in the U.S. that have done so. This closure reflects ongoing debates about capital punishment and concerns over wrongful convictions within the justice system.
