(CNN) Lamar Johnson will soon enter his 25th year behind bars.
The St. Louis man has spent more than half his life in prison for a murder the city’s chief prosecutor says he did not commit.
Johnson, 45, is serving a sentence of life without the possibility of parole in Missouri. But a report from St. Louis Circuit Attorney Kimberly Gardner and the Conviction Integrity Unit outlined what her office called misconduct by police and prosecutors in the case, including perjury, false testimony and the payment of more than $4,000 to the sole eyewitness. The witness later recanted.
