what crime did red commit in shawshank redemption

Red’s crime in The Shawshank Redemption is only fully explained in Stephen King’s original story, where he says Red planned his wife’s murder by tampering with her brakes, but the crash also killed a neighbor and a child. In the film, the exact crime is left vague.

Movie vs. story

• Film: Red’s crime is not spelled out.
• Story: He is responsible for a fatal brake tampering that led to multiple deaths.

What that means

Red is often described as “the only guilty man in Shawshank” because, unlike Andy, his guilt is real and not disputed.

If you want the one-line answer: Red went to prison for murdering his wife in a planned act that also caused other deaths.
