The Mississippi Supreme Court has denied a request to grant a late reprieve in the execution that's set for Wednesday.
Lawyers for the death row inmate are now appealing to the U.S. Supreme Court.
In a one-page order filed Monday in Jackson, state Chief Justice Edwin L. Pittman said the court will NOT change its July 3rd order. That order dismissed Tracy Alan Hansen's application for post-conviction relief and stay of execution.
The appeal to the nation's highest court was filed Monday, but it's not clear when it will be acted on.
If the execution goes forward, it will be Mississippi's first since 1989.
Hansen, now 39, was sentenced to death in the 1987 killing of Trooper Bruce Ladner, who was gunned down after pulling over Hansen's car for speeding on Interstate 10.
State Attorney General Mike Moore and one of his staff attorneys will witness the execution. Moore says others in his office will remain in Jackson to handle appeals.
