Nullification of bite mark evidence frees Dallas man after 28 years in prison

Fifty-nine-year-old Steven Mark Chaney, who spent 28 years of his life in prison due to a murder conviction in relation to the killing of Dallas couple John and Sally Sweek, was freed from jail on Monday, October 12 after the bite mark evidence that led to his conviction was formally discredited.

Chaney was sentenced to life imprisonment in 1989 after dentist Jim Hales told the jury that there was a one in a million chance that the bite marks found on John Sweek’s body were from someone other than Chaney.

State District Judge Dominique Collins overturned Chaney’s murder conviction after granting a joint request from Dallas County District Attorney Susan Hawk of The Innocence Project and the Dallas County Public Defender’s Office. While this is good news for Chaney, he has not been completely cleared of the crimes yet. The Texas Court of Criminal Appeals must review the court’s findings before they grant a full exoneration.
