• 42-year-old Michael Tisius killed two jail guards in an attempt to free someone else from county prison in June 2000.
  • Tisius is set to be executed for his crimes in 2023, after multiple attempts to appeal the ruling. He will be the third person to be executed in Missouri in 2023.
  • The governor of Missouri, Mike Parson, declined clemency for Tisius on June 6, 2023. He claimed "It’s despicable that two dedicated public servants were murdered in a failed attempt to help another criminal evade the law."

Missouri Gov. Mike Parson on Monday declined clemency for a man who faces execution Tuesday evening for killing two jailers in an ill-fated effort to free someone else from a county jail.

Michael Tisius, 42, would be the third person in Missouri, and the 12th person nationally, to be executed in 2023. He's accused of killing officers Leon Egley and Jason Acton in June 2000.

"It’s despicable that two dedicated public servants were murdered in a failed attempt to help another criminal evade the law," Parson, a Republican, said in a statement. "The state of Missouri will carry out Mr. Tisius’s sentences according to the Court’s order and deliver justice."

Tisius has at least one pending court appeal. His appeals and his clemency request have focused on several issues. Among them: Tisius was just 19 at the time of the killings; he had been neglected as a child; and a juror at his 2010 resentencing may have been illiterate — in violation of Missouri law.

The U.S. Supreme Court on Monday declined to halt the execution based on Tisius' age when the crime occurred. A federal judge last week stayed the execution over the claim that a juror was illiterate, but an appeals panel reinstated it. The Supreme Court hasn't yet ruled on that issue.

Elizabeth Unger Carlyle, an attorney for Tisius, said the ups and downs of the appeals are taking a toll on him.

"I think he’s sort of, frankly, on an emotional roller coaster," Carlyle said. "He’s pretty anxious. He doesn’t want to die. I think he’s angry and frightened."

A 2005 Supreme Court ruling prohibits executions for those who were under 18 at the time of the crime. But Carlyle said "emerging science plus information about Mr. Tisius' own brain dictates that they should now change that rule to apply to Mr. Tisius."

A court filing from the Missouri attorney general's office noted that both the original trial jury and the jury at resentencing considered Tisius' age and mental health, "yet both juries still decided to impose the death penalty." The Supreme Court turned aside the appeal without comment.

Advocates for Tisius say he was largely neglected as a child and was homeless by his early teens. In 1999, as an 18-year-old, he was jailed on a misdemeanor charge for pawning a rented stereo system.

In June 2000, Tisius was housed at the small Randolph County Jail in Huntsville with Roy Vance. Tisius was about to be released, and court records show the men discussed a plan in which Tisius would help Vance escape.

Just after midnight on June 22, Tisius went to the jail accompanied by Vance's girlfriend, Tracie Bulington. They told Egley and Acton that they were delivering cigarettes to Vance. The jailers didn't know that Tisius had a pistol.

At trial, Bulington testified that she looked up and saw Tisius with the gun drawn, then watched as he shot and killed Acton. When Egley approached, Tisius shot him, too. Both officers were unarmed.

Tisius found keys at the dispatch area and tried to open Vance's cell, but couldn't. When Egley grabbed Bulington's leg, Tisius shot him several more times.

Tisius and Bulington fled but their car broke down in Kansas. They were arrested in Wathena, Kansas, about 130 miles west of Huntsville. Tisius confessed to the crimes.

Bulington and Vance are serving life sentences.

Defense attorneys have argued that the killings were not premeditated. Tisius, they said, intended to order the jailers into a holding cell and free Vance and other inmates. Tisius’ defense team issued a video last week in which Vance said he planned the escape attempt and manipulated Tisius into participating.
