On September 24, 2024, Missouri executed Marcellus Williams for the 1998 murder of Felicia Gayle. Multiple courts, including the U.S. Supreme Court, denied last-minute appeals.

Both of the main witnesses against him had incentives to testify, and this has raised concerns about the reliability of their statements. Meanwhile, DNA evidence emerged in recent years that created beyond-reasonable doubt. Did Missouri execute an innocent man?
