OKLAHOMA CITY (Reuters) - Oklahoma on Tuesday was scheduled to execute a man convicted of raping and murdering two elderly women in the 1980s, while a federal appeals court panel has stayed a Missouri execution planned for hours later.
Missouri appealed the 2-1 ruling by the Eighth Circuit U.S. Court of Appeals panel to stay the execution of Allen Nicklasson, 41, who was found guilty of killing a stranger who offered him roadside assistance. Nicklasson has raised claims that his trial and appeals counsel were ineffective.
The full Eighth Circuit was expected to hear arguments and rule Tuesday morning on the state's request to lift the stay of Nicklasson's execution, which is set for early Wednesday at a Missouri prison.
The Missouri Department of Corrections is proceeding with its plans for the execution unless instructed differently by the state attorney general, spokesman Mike O'Connell said.
Oklahoma is scheduled to execute Ronald Clinton Lott, 53, by lethal injection at a state prison after 6 p.m. Central Time (0000 GMT) on Tuesday.
If carried out, the executions of Lott and Nicklasson would be the 37th and 38th in the United States this year, according to the Death Penalty Information Center.
Lott was convicted of raping and killing Anna Laura Fowler, 83, in 1986 and Zelma Cutler, 90, in 1987 in their Oklahoma City homes after DNA evidence linked him to the crimes.
According to Oklahoma criminal appeals court records, evidence presented at trial suggested Lott attacked the women and sat on their chests, breaking their ribs. Both had numerous bruises and were asphyxiated.
Another man, Robert Lee Miller Jr., had originally confessed to the rape and murder of the two women and served 11 years, seven on death row, before DNA evidence led authorities to Lott. Miller was released in 1998.
Lott would be the fifth man executed in Oklahoma in 2013. The state is also scheduled to execute Johnny Dale Black, 48, on December 17 for his conviction in the 1998 stabbing death of Ringling, Oklahoma, horse trainer Bill Pogue.
In the Missouri case, Nicklasson was found guilty of murder for the August 1994 shooting of motorist Richard Drummond, who stopped on a highway to help Nicklasson and two other men whose car had broken down.
The men had burglarized a home where they stole guns and ammunition before their vehicle broke down. When Drummond stopped to offer a ride, the men abducted him, took him to a wooded area and shot him in the head, according to court records. One of the men, Dennis Skillicorn, was executed in 2009. The other man, Tim DeGraffenreid, was 17 at the time. He pleaded guilty to second-degree murder and received a reduced sentence.
Nicklasson and Skillicorn were also convicted of killing an Arizona couple while they were on the run after killing Drummond. Nicklasson would be the second person executed in Missouri this year.
Nicklasson had been scheduled to die October 23, but Missouri Governor Jay Nixon halted the execution due to broad criticism over the state's planned use of the drug propofol, widely used as an anesthetic in medical procedures.
The case is one of many caught up in a nationwide debate over what drugs can or should be used for executions as capital punishment opponents pressure pharmaceutical companies to cut off supplies of drugs for executions.
Missouri in November used pentobarbital, a short-acting barbiturate, mixed by a compounding pharmacy to execute serial killer Joseph Paul Franklin.
