This week we explore the harrowing story of Lamar Johnson, a St. Louis man who spent nearly three decades behind bars for a murder he did not commit.

In 1994, Johnson was convicted of killing his friend Marcus Boyd — despite having an alibi placing him miles away at the time of the crime. The case against him relied heavily on shaky eyewitness testimony and police misconduct, with no physical evidence tying him to the scene. Over the years, witnesses recanted, new confessions came to light, and mounting evidence pointed to Johnson’s innocence.
