In 1983, Calvin C. Johnson, Jr. stood in a courtroom and was sentenced to life in prison for a rape and burglary he said he did not commit. "With God as my witness, I have been falsely accused," Johnson told the judge, "I'm an innocent man." After 16 years in prison, Johnson was exonerated with the help of the Innocence Project and state-of-the-art science. He was the 61st person in the US, and the first in Georgia, to be proved innocent by DNA testing. Hear firsthand about Johnson's wrongful conviction and imprisonment, and the events that led to his exoneration.
