Dallas County man freed after serving 25 years for murder over faulty science of bite marks

Steven Mark Chaney is a free man after spending 25 years behind bars after the faulty science of bite marks sent him to prison for murder.
Dentist Jim Hales told a Dallas County jury that there was a “1 to a million” chance that someone other than Chaney made the bite marks on John Sweek’s body. Now, Hales says the science used to convict Chaney has been discredited.
Outside the courtroom, Chaney bear-hugged family members, including his wife, mother and four brothers.
