PHOENIX (AP) -- An Arizona woman who spent more than two decades on death row in her 4-year-old son's killing saw her murder charge dismissed Monday, bringing an end to a controversial case that relied almost entirely on the work of a detective with a long history of misconduct.
Debra Milke hugged her supporters and sobbed as she left the courtroom, where a judge formally dismissed the case, saying it cannot be tried again, less than a week after prosecutors lost their final appeal. In a brief hearing, Judge Rosa Mroz also allowed Milke, who has been free on bond since 2013, to have her electronic-monitoring ankle bracelet removed.

Milke, who spent more than two decades on death row, was released on bond on Friday, Sept. 6, 2013, with a judge saying there's no direct evidence linking her to her son's death other than a purported confession to a detective. The state Court of Appeals ruled Thursday, April 17, 2014 that former Phoenix Police Department detective Armando Saldate Jr. will be forced to testify at the Milke retrial after he asserted his right against self-incrimination and had been refusing the take the stand again.

Milke emerged from a conference room a short time later without the device.
"It feels good," Milke said, pulling up one pant leg to show her unencumbered ankle.
Milke was convicted of murder in 1990 in the death of her son, Christopher. Authorities say Milke dressed him in his favorite outfit and told him he was going to see Santa Claus at a mall in December 1989. He was then taken to the desert near Phoenix by two men, one of whom was Milke's roommate, and shot in the back of the head.
Authorities say Milke's motive was that she didn't want the child anymore and didn't want him to live with his father. Milke has maintained her innocence and denied that she confessed to the killing. The two men who led her child to his death were convicted of murder but refused to testify against Milke.
An appeals court overturned Milke's conviction in 2013, ruling that prosecutors failed to disclose a detective's history of misconduct. Her conviction was based entirely on a confession Milke gave to the now-discredited detective, Armando Saldate.
Multiple rulings in other cases said the now-retired officer either lied under oath or violated suspects' rights during interrogations, according to the federal appeals court.
In a scathing 2013 opinion, that court leveled harsh criticism over the case.
"No civilized system of justice should have to depend on such flimsy evidence," the 9th U.S. Circuit Court of Appeals said.
Michael Kimerer, one of Milke's attorneys, said Monday that he was still in disbelief that "a long, long journey with so many ups and downs" ended with his client's freedom.
"She was innocent. It was all based upon a police officer that just totally lied," Kimerer said outside court. "To see her free today and totally free and exonerated, it's an unbelievable feeling - just unbelievable."
Saldate had said he would not testify at any retrial, citing fears of potential federal charges based on the 9th Circuit's accusations of misconduct. Both county and federal authorities said they did not intend to seek charges against the detective based on the accusations, and a state appeals court later ruled that Saldate would be compelled to testify even against his will.
Maricopa County Attorney Bill Montgomery last week called the decision not to let the case be retried "a dark day for Arizona's criminal justice system."
Milke sued the city of Phoenix, Maricopa County and numerous individuals earlier this month, alleging authorities violated her civil rights. She also contends she was denied a fair trial and was a victim of malicious prosecution.
