Ford, who was the same age as Stroud, was wrongly convicted for of robbing and murdering a local jeweler in Shreveport, Louisiana

A prosecutor in the case in which a man was wrongly convicted of robbing and murdering a local jeweler described himself as 'a coward' after admitting his role in the false imprisonment.

Marty Stroud said he was 'caught up in the culture of winning' in 1984 when Glenn Ford was falsely convicted and later sentenced to death for the murder of Isadore Rozeman in Shreveport, Louisiana.

Ford had spent three decades in a maximum-security prison when in March 2014 it was learned that the state had convicted the wrong man.

The father-of-four was released from prison soon after, but was diagnosed with lung cancer soon afterwards and died in hospice care in June this year. He was 65.

Stroud, who was the prosecutor in the case, has confessed his role in the conviction, in an episode of CBS's 60 Minutes airing on Sunday.

Now 64, he said that it was his first-ever death penalty case and he ignored evidence that suggested other people were involved in the murder.

'I should have followed up on that. I didn't do that. I think my failure to say something can only be described as cowardice. I was a coward,' he told host Bill Whitaker.

'I was arrogant, narcissistic, caught up in the culture of winning.'

A remorseful Stroud struggles with living with the truth of what happened so many years ago.

'I've got a hole in me through which the north wind blows. It's a sense of coldness, it's a sense of just disgust,' he said.

Before Ford's death, Stroud wrote him a letter in which he admitted he was to blame for mistakenly putting him behind bars for the fatal shooting of a jeweler, despite no murder weapon or witnesses placing him at the scene.

Ford, who was incarcerated at the age of 32, did not have much sympathy for Stroud.

'He didn't only take from me - he took from my whole family... I don't [forgive him], but I'm still trying to,' he said in an interview before his death.

Ford filed for $330,000 compensation for his wrongful imprisonment, but the State of Louisiana denied his case.

During his trial, Ford admitted to pawning some of the stolen jewelry but said he did not commit the murder.

The State of Louisiana argued that in order for Ford to have received compensation, he had to be innocent of all things he was accused of during his original trial.
