Missouri Gov. Jay Nixon has refused to halt the execution of white supremacist serial killer Joseph Paul Franklin, calling his crime in Missouri a "cowardly and calculated shooting."
Nixon's office announced the decision Monday afternoon.
Franklin is scheduled to die at 12:01 a.m. Wednesday for killing 42-year-old Gerald Gordon in a sniper attack outside a suburban St. Louis synagogue in 1977. It was one of as many as 20 killings committed by Franklin, who targeted blacks and Jews in a cross-country killing spree from 1977 to 1980. He was convicted of seven other murders but the Missouri case was the only one resulting in a death sentence.
The execution would be the first in Missouri in nearly three years and the first ever in the state to use a single execution drug, the sedative pentobarbital.
