Lawyers have presented arguments before the state Court of Appeals in the case of an Arizona mother whose 1990 conviction in the killing of her son was overturned after she spent more than two decades on death row.
Authorities say Debra Milke had two men kill her 4-year-old son in 1989. But a federal appeals court last year overturned her murder conviction, setting the stage for a 2015 retrial.
The case against her rested largely on her purported confession, which a now-retired detective did not record. His credibility has been called into question by the appeals court that overturned Milke's conviction. The former detective is refusing to testify again.
Prosecutors on Wednesday asked the state Court of Appeals to reverse a judge's ruling that allowed him to assert his right against self-incrimination.
