Missouri judge overturns wrongful murder conviction of man imprisoned for over 30 years

A Missouri judge on Monday overturned the conviction of Christopher Dunn, who has spent more than 30 years in prison for a killing he has long contended he didn't commit.

The ruling is likely to free Dunn from prison, but it wasn't immediately clear when that would happen. He has been serving a sentence of life without parole.

St. Louis Circuit Judge Jason Sengheiser's ruling came several weeks after he presided over a three-day hearing on Dunn's fate.
