Judge dismisses charges in woman's bite-mark conviction

A judge has dismissed all charges against a Pennsylvania woman who spent nearly 11 years incarcerated on charges she helped beat a man to death in 2001.

Fayette County Judge John Wagner had overturned 39-year-old Crystal Weimer's conviction and sentence in October. Monday's decision means the charges against her cannot be retried by the district attorney.

Wagner overturned the conviction after a bite mark expert said his trial testimony against her was based on "junk science."

Weimer has repeatedly insisted she's innocent in the 2001 beating death of 21-year-old Curtis Haith.

She was convicted of third-degree murder in 2006 and sentenced to 15 to 30 years in prison after a man imprisoned in the case had testified Weimer helped lure Haith to the scene.
