Missouri executions

"We're talking about constitutional rights in someone's dying moments," one advocate said.

Lethal injection is tainted with error, ineptitude and secrecy that's led to many botched executions and unnecessary suffering. Missouri passed a law shielding the identity of the people involved in lethal injections, following a scandal over the credibility of its chief executioner.

Of the past 10 people who have faced execution in Missouri, at least six had children. For kids of people on death row, there are complicated emotions and little support.

A jury found Lance Shockley guilty of a 2005 murder but deadlocked on the punishment. A judge in Carter County issued the death sentence.

Missouri law allowed a judge to sentence Shockley to death in 2009 even after a jury deadlocked and couldn’t decide on the punishment. Last week, advocates marched to Gov. Mike Kehoe's office to deliver a petition with 31,000 signatures asking for an investigation.

Only Missouri and Indiana allow judges to impose capital punishment when a jury can't decide whether to sentence a defendant to death. Lance Shockley is scheduled to be executed next week for a 2005 murder he maintains he did not commit.

Missouri is one of two states where a judge can hand down death when juries cannot agree unanimously on a sentence. Since the law changed in 1984, at least 18 people have been sentenced to death by a judge, and four have been executed.

The family of Marcellus Williams has reported receiving death threats since the state of Missouri executed him last week. A representative of his son said the threats were made via phone calls, emails and anonymous social media messages.

Without intervention from the U.S. Supreme Court, Marcellus Williams will be executed after 6 p.m. Tuesday. Gov. Mike Parson has said he will not grant clemency to Williams.

Williams is set to be executed Tuesday for the 1998 killing of Felicia Gayle, a crime that he has always denied any role in. His attorneys have launched multiple legal battles in an attempt to save his life.

"Taking the life of Marcellus Williams would be an unequivocal statement that when a white woman is killed, a Black man must die. And any Black man will do," wrote NAACP president Derrick Johnson.

Without intervention from Gov. Mike Parson or the U.S. Supreme Court, Marcellus Williams will be executed Sept. 24. Williams was nearly saved from death row after prosecutors and attorneys reached a plea deal for life in prison, but it was later withdrawn.
