A judge says Nevada can’t use its supply of the drug midazolam in the lethal injection of a convicted killer. District Judge Elizabeth Gonzalez wrote that Nevada prison officials obtained drug manufacturer Alvogen’s sedative midazolam through “subterfuge,” or deceit, adding that the purchase was made in “stark contrast” to previous attempts to buy medication for capital punishment. The ban essentially shuts down the possible execution of Scott Dozier for the foreseeable future. Dozier’s execution was halted in July, for the second time in nine months, after Alvogen sued the prison system. Dozier was sentenced to die in 2007 after first-degree murder and robbery convictions in the killing of Jeremiah Miller. Dozier would be the first prisoner executed in Nevada since 2006.
