CINCINNATI (AP) — A former Ohio police captain who has spent 14 years in prison has new DNA test results that his attorneys say prove his innocence.

Doug Prade could become the latest of more than a dozen prisoners across the country to be set free after comparisons between their teeth and bite marks on victims turned out to be wrong.

Prade was found guilty in 1998 of the aggravated murder of his ex-wife, an Akron doctor who was shot outside her office. He was sentenced to life in prison.

Attorneys say a new test finds that male DNA from around a bite mark on a lab coat that his wife was wearing when she was killed is not Doug Prade's.

A judge could exonerate Prade, order a new trial or find that the DNA test isn't strong enough for either.
