An arrest would cap a revived investigation into the infamous 2001 killing in Washington that destroyed the career of former US congressman Gary Condit of California.
Investigators in 2002 questioned Ingmar Guandique, now 27, in the slaying after he was convicted of attacking two women joggers in Washington’s Rock Creek Park. They didn’t charge him, but statements he made to people while in prison helped lead investigators back to him, the source said.
A law enforcement official who has spoken to investigators said the break came in part from DNA evidence that was either re-tested or collected, and it was connected to Guandique.
Local prosecutors have convened a grand jury in the District of Columbia, and an arrest warrant is expected within the next few days, the officials said.
Chandra Levy was 24 and had just completed an internship with the US Bureau of Prisons when she disappeared in Washington DC in May 2001. Her remains were found in the park a year later.
Authorities questioned Condit, her congressman, in the disappearance, but he was never a suspect in her death. Condit, a popular Democrat for a dozen years in his district, was reportedly having an affair with Levy, and the negative publicity from the case was cited as the main reason for his overwhelming primary loss in 2002.
Guandique was sentenced to 10 years in prison for attacking two women in the park.
