Prosecutors say they will not retry a man convicted of killing Washington intern Chandra Levy. The U.S. Attorney's office said in a statement Thursday, July 28, 2016, that the office has moved to dismiss the case charging Ingmar Guandique with Levy's 2001 murder. According to the statement, prosecutors concluded they could not convict Guandique "based on recent unforeseen developments that were investigated over the past week."

The 15-year-old mystery of who killed Washington intern Chandra Levy is again an open question after prosecutors dropped charges against the man who once stood convicted of her murder.

A judge Thursday dismissed all charges against Ingmar Guandique after prosecutors said new developments left them unable to prove his guilt beyond a reasonable doubt. Prosecutors refused to discuss details of what led them to abandon their case.

Levy's 2001 disappearance became a national obsession after she was romantically linked to Gary Condit, then a Democratic congressman from California.

Condit was once was a suspect, but authorities eventually charged and convicted Guandique.

Last year, though, Guandique was granted a new trial after doubts emerged about a jailhouse informant who was the key witness at Guandique's initial trial.
