A group of death penalty opponents are urging state law makers to halt executions. Missourians for alternatives to the death penalty gathered at the capital yesterday to mark the 25 years since the state resumed executions. And one of the state’s top ranking democrats also filed a measure on Monday to review Missouri’s lethal injection protocols and put executions on hold while the review takes place. Under that proposal, an eleven person commission would study all aspects of lethal injection in the state and all executions would be halted while the commission conducts its review. The measure has not yet been formally introduced in the state’s House of Representatives. It would become effective immediately if passed. This latest activity surrounding Missouri’s death penalty comes as the state prepares to execute Herbert Smulls on January 29th who would be Missouri’s third lethal injection in two months.
