Officer Betty Shelby, 42, entered a not guilty plea to first-degree manslaughter charges in the shooting death of Terence Crutcher, 40.
Scores of people gathered to say farewell at a memorial service for Terence Crutcher. Family and friends recalled him as a loving father with a passion for singing gospel music.
The Tulsa County District Attorney's office said that Shelby acted "unreasonably by escalating the situation from a confrontation," and became "emotionally involved," according to an affidavit obtained by ABC News.
