Missouri Prepares to Execute Man for Killing Two Jail Guards Despite Pleas for Clemency

Michael Tisius is scheduled to be executed in Missouri on Tuesday for killing two jail guards in 2000 when he was 19 years old.
Tisius' legal team has appealed for clemency to Missouri Governor Mike Parson citing Tisius' age at the time of the crime, a neglectful childhood, and a potentially illiterate juror.
The U.S. Supreme Court denied a request to halt the execution based on Tisius' age but has not ruled on the issue of the potentially illiterate juror.
Advocates argue emerging science about brain development for those under 18 should prohibit executions for crimes committed at that age.
Tisius' defense team claims the killings were not premeditated but part of a botched escape attempt in which Tisius was manipulated into participating.
