Steven Mark Chaney who was imprisoned for 28 years for the 1987 murders of two people in Dallas, TX was released this week after his conviction based upon discredited bite-mark evidence was thrown out.  Chaney was sentenced to life in prison after a forensic dentist told a Dallas jury in 1989 that there was a 1 in 1,000,000 chance that the murderer was someone other than Chaney.  The bite-marks were allegedly found on John Sweek.  The dentist has since recanted his testimony.  State District Judge Dominique Collins overturned Chaney’s conviction after receiving a joint request from the District Attorney Susan Hawk, the Innocence Project, and the Public Defender’s Office.

Chaney, 59, will remain free while the Texas Court of Criminal Appeals reviews the case.

“I could sit and recount all the wrongs,” Chaney told reporters, “The loss of my oldest stepson, my oldest grandchild two years ago, but this is a time for rejoicing…”

At least one juror after his initial trial said that the bite-mark evidence convinced them of Chaney’s guilt, despite testimony from 9 witnesses that he was somewhere else during the murders of John and Sally Sweek.  In recent years, forensic scientists have raised doubts about the reliability of bite mark evidence among others.  In 2009, the National Academy of Sciences published a report concluding that there was insufficient scientific basis to conclusively match bite marks to individuals.  The Texas Forensic Science Commission is reviewing cases in which bite analysis contributed to a conviction to determine whether they warrant further investigation.  In addition, defense lawyers also allege that prosecutors knowingly presented false evidence that blood had been found on Chaney’s shoes.  Prosecutors withheld notes from another expert who said that there was no blood.  They also say that prosecutors elicited false testimony from the co-worker of Chaney who initially told police that Chaney had asked him to tell authorities that he had last been at the victims’ home a week before their murder.  At trial, the co-worker told the jury that Chaney had asked him to be his alibi.  Chaney’s attorneys have filed court papers saying new evidence establishes he is innocent.

“We’re confident that when the reinvestigation is complete, the district attorney’s office will be in a position to formally agree that he is innocent of this crime,” said Julie Less, exoneration attorney for the Dallas County Public Defender’s Office, in a statement.
