A former Arizona death row inmate whose conviction in her son's killing was overturned has filed a lawsuit alleging authorities violated her civil rights.

Debra Milke filed the lawsuit Friday against the city of Phoenix, Maricopa County and numerous individuals.

Milke contends she was denied a fair trial in her 4-year-old son's 1989 killing and was a victim of malicious prosecution.

A federal appeals court that threw out Milke's conviction had ruled prosecutors failed to disclose a history of misconduct by a detective.

Prosecutors are appealing a state appeals court's ruling that retrying Milke would amount to double jeopardy.

Prosecutors declined to discuss the lawsuit.

Phoenix's acting city attorney didn't immediately respond to a request for comment.

Milke has been free on bail since 2013 while awaiting possible retrial.
