(Reuters) -A man who fatally shot two Missouri jail guards in 2000 was scheduled to be executed as early as Tuesday after the governor and the U.S. Supreme Court declined to intervene, even though several jurors in the case petitioned for a reduced sentence.
Michael Tisius, 42, was convicted in 2001 of murdering Randolph County sheriff’s deputies Jason Acton and Leon Egley, both unarmed, during a failed attempt to help a former cellmate escape from jail.
Lawyers for Tisius have argued in petitions seeking a reprieve that he should be spared the death penalty given that he was 19 at the time of the killings and suffered from lifelong brain impairments and mental illness.
According to his attorneys, Tisius was traumatized by severe physical abuse and neglect as a child, aggravating cognitive deficits that rendered him vulnerable to manipulation by others, including his older cellmate, Roy Vance, who persuaded Tisius to go along with the ill-fated escape plan.
Six former jurors among the 12 who voted unanimously to recommend the death penalty for Tisius at his trial in 2010 said in sworn affidavits as part of a separate clemency petition that they now favored or would accept life imprisonment instead of capital punishment.
Governor Mike Parson, a Republican, declined the clemency bid on Monday.
“Missouri’s judicial system provided Mr. Tisius with due process and fair proceedings for his brutal murders of two Randolph County jail guards,” the Republican governor said in a statement.
The U.S. Supreme Court denied two petitions for a stay of execution on Monday and two more on Tuesday, paving the way for the Missouri Department of Corrections to put him to death by lethal injection sometime between 6 p.m. (2300 GMT) on Tuesday and 6 p.m. on Wednesday.
Tisius was accused of plotting with Tracie Bulington, Vance’s then-girlfriend, to help Vance escape from jail after Tisius was released from the lockup. He had met Vance while serving time for a probation violation stemming from a misdemeanor theft case, according to his attorneys.
The two guards were shot and killed when the breakout attempt went awry. Burlington and Vance were later sentenced to life in prison for their roles in the incident.
