Foxnews.com: Police are close to arresting an inmate they've already interviewed in the eight-year-old murder case of Chandra Levy and charging him in her disappearance, FOX News has confirmed.

Law enforcement officials said an arrest warrant will be issued for Ingmar Guandique, who is currently in prison in California.

Officials said Guandique will be served papers there and likely then flown to Washington, D.C., to hear the charges against him.

D.C. authorities submitted evidence to the U.S. Attorney's office to obtain the arrest warrant.

Guandique is reportedly in jail for assaulting two women in Rock Creek Park, the same park where Levy's remains were found a year after she vanished, according to WRC-TV in Washington.

Another inmate told investigators that Guandique confessed to Levy's murder, according to the station. But Guandique changed his story when speaking to investigators. He allegedly told police that he saw Levy several times in the park, but played no part in her death.

Levy's parents, Robert and Susan Levy of Modesto, Calif., said Friday night that police told them there had been a break in the case, KXTV in Sacramento reported.

Levy, 24, of Modesto, Calif., had just completed an internship at the U.S. Bureau of Prisons when she disappeared from her apartment on May 1, 2001. Her remains were found in 2002, more than a year after her disappearance.

The cause of death was ruled a homicide, but nobody was ever charged.

Levy was romantically linked to married California congressman Gary Condit. He denied any involvement in or knowledge of Levy's disappearance or death.

But he acknowledged to investigators that they had an intimate relationship. Levy's parents also said their daughter had told them about the affair.

Though police never formally named Condit a suspect, the negative publicity from the case was cited as the main cause of the Democrat's re-election defeat in 2002.
