USA - Utah. Utah has gone more than a decade without carrying out an execution.

June 18, 2020:

Utah has become the latest U.S. state to have gone more than a decade without carrying out an execution. The state last put a prisoner to death on June 18, 2010, when it executed Ronnie Gardner by firing squad.

Utah joins a list of 34 states — more than two thirds of the country — that either do not have the death penalty or have not carried out an execution in at least a decade. Twenty-two states no longer authorize capital punishment. Twelve of the 28 states (42.9%) that do have not executed anyone in at least 10 years. It has been even longer — 12 years — since Utah last imposed a new death sentence.

The decline of the death penalty in Utah is part of a sweeping trend away from the death penalty in the western United States. In the last two years, Washington and Colorado have abolished the death penalty, California has imposed a moratorium on executions and dismantled its execution chamber, New Mexico has cleared its death row, and Oregon and Arizona have both narrowed the circumstances in which the death penalty may be imposed. 2019 marked the fifth consecutive year with no executions west of Texas.
