The Missouri Supreme Court on Wednesday set a June execution date for man convicted of killing two Missouri jailers during a botched attempt to free a friend.

Michael Andrew Tisius is scheduled to be executed June 6 at the state prison in Bonne Terre for the shooting deaths of Randolph County jailers Jason Acton and Leon Egley.

In 2000, Tisius and Tracie Bulington entered the lobby of the jail in Huntsville, aiming to break out Bulington’s boyfriend, Roy Vance, prosecutors said. Tisius fired on the two officers, killing them. The plot failed because the intruders couldn’t find the cell keys.

Defense attorneys had argued that Tisius intended only to order the jailers into a holding cell and free Vance and other inmates.

Bulington, and Vance are serving life sentences.
