The Missouri attorney general plans to retry a northwest Missouri man after the state Supreme Court overturned his conviction for the 1990 murder of a neighbor.

The state’s high court ruled Tuesday that prosecutors had failed to share evidence that could have helped Mark Woodworth’s defense against charges that he fatally shot Catherine Robertson and wounded her husband.

The court ordered Woodworth released unless prosecutors decide to retry him.

Later Tuesday, a spokeswoman said Attorney General Chris Koster intends to retry Woodworth.

Woodworth was 16 years old at the time of Robertson’s death. He lived near their rural Chillicothe home, and his father had farmed with the Robertsons.
