KNOXVILLE, Tenn. (AP) — A judge has ordered a new trial for a Knoxville woman convicted in her husband's death after determining that another judge's addiction to prescription painkillers tainted her initial trial.

Multiple media outlets report Senior Judge Paul Summers issued a ruling Thursday, granting a retrial for Raynella Dossett Leath.

Leath is serving life in prison after being convicted in 2010 of first-degree murder in the 2003 shooting death of David Leath.

In March, she asked the judge to overturn her conviction and allow her a new trial, saying there was new evidence that Knox County Criminal Court Judge Richard Baumgartner, who oversaw the initial case, used drugs during her trial.

Summers said an investigation proved that Baumgartner's addiction to drugs impacted the trial, robbing her of a constitutionally sound proceeding.
