Police Explore Several Theories in Missing Intern Case

Washington, D.C. police will use dogs to check area landfills as they explore a theory that missing intern Chandra Levy was killed near her apartment and her body was placed in a nearby trash bin, Fox News has learned.

Police contacted vendors who service the trash cans near her apartment in the trendy Dupont Circle section of the city and asked them for a list of landfills that they use, according to a police source.

But it is just one theory, the source stressed, adding that police still cannot rule out suicide or that Levy has assumed a new identity.

The U.S. Attorney's Office will coordinate an FBI interview with Congressman Gary Condit's wife to double-check his stated whereabouts the week Levy disappeared. The interview likely will take place in California in the next couple of days. The FBI will share information with police.

The cops also want to ask whether Mrs. Condit saw or talked to Levy while in Washington. The interview could also be used to develop a personality profile of Levy the FBI is creating in hopes of learning what happened to her, the sources said.

Condit told police that his wife, who lives in Ceres, Calif., had visited Washington and stayed at his apartment at the time of Levy's disappearance. The congressman reportedly had a busy schedule that week, and spent the day Levy was last seen either in meetings, at work or with his wife.

Condit, a 53-year-old California Democrat who represents Levy's hometown, "strongly suggested" to police last Saturday that he and the 24-year-old Bureau of Prisons intern were lovers, law enforcement sources said.

Condit also said that he broke off his close friendship with Levy two days before she disappeared April 30, law enforcement sources told Fox News. The sources also said Condit told police Levy had a hard time accepting his attempt to distance himself from her.

Condit's chief of staff, Mike Lynch, denied this report on Thursday. Lynch also reiterated that Condit has no information about Levy's disappearance. Levy was last seen April 30.

Police have no evidence of foul play in Levy's apartment, and in addition to the e-mail she sent her mother May 1, police have other evidence that she was inside her apartment for much of that day.

Police will also reinterview people in her apartment building and recheck to see if any have criminal records or saw anything unusual that day or soon after.

A source close to Condit gave ABC News the congressman's schedule from April 28 to May 3, the time his wife was in Washington.

On April 30, Condit was picked up by his staff for work in the morning, attended a lunchtime event at the White House, worked at his Capitol Hill office and spent the evening at his Washington home with his wife.

The next day was similarly accounted for.

FBI agents have also interviewed Levy's California friends and neighbors in recent days.

Levy's parents told police that before she disappeared, she'd received a $100 check from a relative. The fact that it was missing from the apartment but never cashed could lend credence to the possibility that she was the victim of foul play. Levy's parents also said they had no reason to believe their daughter was on any medication when she vanished.

Meanwhile, a 39-year-old United Airlines flight attendant has confessed to ending a year-long affair with Condit upon hearing news of the Levy case, sources told Fox News.

Ann Marie Smith's attorney told Fox News his client has been interviewed by the FBI twice. 

Condit's attorney said he had no comment on this matter.
