Missouri's execution of the "Good Samaritan Killer" remains on hold.
Allen Nicklasson had been scheduled to die by lethal injection at 12:01 a.m. Wednesday for killing businessman Richard Drummond in 1994. Drummond was shot to death after stopping to help when a car carrying Nicklasson and two others stalled along I-70 in central Missouri.
Monday night, a three-judge panel of the 8th U.S. Circuit Court of Appeals granted Nicklasson a stay of execution. Nicklasson is arguing that he didn't receive adequate legal representation at his trial.
Missouri Attorney General Chris Koster appealed that stay to the U.S. Supreme Court Tuesday evening. Koster says the high court told his office that no ruling would be issued before 8:00 a.m. on Wednesday.
If the court rules against Nicklasson, he could be executed at any time on Wednesday.
