The Missouri Supreme Court on Wednesday set a May execution date for convicted killer Russell Bucklew, continuing a trend of scheduling one execution per month.
Bucklew is set to die by injection at 12:01 a.m. May 21 for killing a man in Cape Girardeau County in 1996.
Missouri has executed five men since November -- one each month through March. William Rousan is scheduled to be put to death April 23 for killing a St. Francois County couple in 1993.
Bucklew's attorney, John William Simon, says he will continue efforts in the courts to halt the execution, and will seek clemency from Gov. Jay Nixon.
Bucklew was convicted in the fatal shooting of Michael Sanders, a romantic rival, then abducting and raping Bucklew's ex-girlfriend.
