Walter McMillian is a man who is wrongly convicted of murder in *Just Mercy*. He spends years on death row until Bryan Stevenson and the Equal Justice Initiative help secure his release. Although he has personal flaws, like having an affair and drinking too much, Walter is described as kind, decent, and consistently trying to do the right thing. His wrongful conviction and eventual freedom highlight the broader injustices Stevenson fights against.

In *Just Mercy*, Ralph Myers is a crucial witness in Walter McMillian’s trials. Initially, he testifies falsely against Walter due to coercion and threats but later redeems himself by contacting Stevenson to recant his testimony. Myers, who has a disfigured face and troubled past, provides key testimony to overturn Walter's conviction.

Sheriff Tom Tate is the corrupt and racist county sheriff responsible for Walter McMillian's wrongful conviction in *Just Mercy*. New to his position during the case, Tate is pressured to solve the murders and resorts to hiding evidence and coercing Ralph Myers into false testimony. He values his standing in the community over justice and truth.
