Rhode Island prosecutors are asking the state's highest court to revisit a decision granting a new trial to a man convicted of beating a Woonsocket woman to death 34 years ago.

Attorney General Peter Kilmartin's Office has filed a petition to re-argue the case of Raymond Tempest.

The motion comes after the state Supreme Court upheld a lower court decision that Tempest was entitled to a new trial. The court found that Tempest was denied some evidence by prosecutors that could have been used to impeach witnesses.

The state is disputing the value of evidence the court determined had been withheld.

Tempest was convicted in 1992 of second-degree murder in Doreen Picard's 1982 death. He was sentenced to 85 years in prison but has always maintained his innocence.
