Judge denies new trial for Ohio policeman in ex-wife's death

A judge in Ohio won't allow a new trial for a former Akron police captain convicted of killing his ex-wife in 1997.

Friday's ruling comes three years after a now-retired judge exonerated the ex-officer and ordered his release from prison.

Douglas Prade was exonerated after experts testified that male DNA found on a bite mark on his slain ex-wife's medical lab coat wasn't his.

An appeals court overturned the decision in 2014. Prade was sent back to prison a little over a year after he was released.

His attorneys based Prade's request for a new trial on changing standards in forensic dentistry since his first trial.

But the judge ruled that the bite mark evidence was not the only reason for his conviction.
