DALLAS -- (KDAF) -- A Dallas man is now free after spending more than a quarter-century in prison.
Way back in 1987, cops found what looked like a bite mark on a man who had been stabbed to death. At trial, experts supposedly "matched" that bite to Steven Mark Chaney of Dallas. That testimony was a key part of the prosecution's case.
Chaney was convicted and sentenced to life in prison.
