Missouri corrections officials say they will use a lethal drug provided by a new supplier in the state's fourth execution in four months.
Convicted killer Michael Taylor is scheduled to die at 12:01 a.m. Wednesday. Several court appeals have been filed seeking to spare his life, and Gov. Jay Nixon is weighing a clemency request.
Taylor's attorneys are questioning Missouri's use of the new, unnamed compounding pharmacy to provide the pentobarbital for his execution. They also allege that the state executes men before appeals are complete, and say Taylor's trial attorney was ineffective.
Taylor and Roderick Nunley were convicted of abducting 15-year-old Ann Harrison as she waited for a Kansas City school bus in 1989, then raping and killing her. Nunley is also on death row.
