Police to return to parks in Levy case

Experts: Condit damaged own reputation

Police say Chandra Levy was last seen April 30 but was logged onto her computer at home on May 1

WASHINGTON (CNN) -- Police are expected to resume their search of city parks Monday as the investigation into Chandra Levy's nearly three-month-old disappearance plows ahead with no firm lead on what happened to the former federal Bureau of Prisons intern.

Meanwhile, legal experts said Sunday that Rep. Gary Condit, D-California, has hurt his credibility because of his actions related to the case.

Condit, who police sources said admitted to a romantic relationship with Levy during his third interview with police, has not taken an FBI polygraph, although his lawyer arranged for one that was privately administered.

A law enforcement source said Saturday that authorities "probably" want to interview Condit for a fourth time.

Speaking on CNN's Late Edition with Wolf Blitzer, Lanny Davis, special counsel under former President Bill Clinton, said Condit has harmed his reputation, regardless of how the Levy case turns out.

"Let me make it clear, I presume he's completely innocent of any involvement with Chandra Levy. And if it turns out to be the case, he will claim vindication. I will claim exactly the opposite. You did injury to yourself and to the investigation by not telling the truth upfront," Davis said.

Levy, a former intern with the U.S. Bureau of Prisons, was last seen April 30 at her Washington gym.

Condit, 53, is one of more than 100 people police have interviewed in connection with the case, but he has generated the most media attention because of his status as a U.S. congressman and because of his reported extramarital affair with the 24-year-old woman. Police say repeatedly that he is not a suspect in the case.

He has never publicly acknowledged a romantic relationship with Levy and has denied it through his aides. Levy's family believes he was having an affair with Levy and police sources said Condit admitted to an affair in an interview.

Former U.S. Attorney Joe DiGenova said Condit's actions amounted to obstruction of justice.

Condit's attorney has maintained that his client has cooperated with police, noting his willingness to let authorities search his apartment and give a DNA sample.

DiGenova, however, cited Condit's initial failure to acknowledge a romantic relationship with Levy to police, the accusation from a flight attendant that he had asked her to mislead authorities about their romantic relationship and Condit's disposal of a watch case hours before police searched his apartment.

Police sources Friday said that four hours before police began a July 10 search of Condit's apartment, the lawmaker was spotted dumping something into a trash can in a nearby Virginia suburb. Officers found a watch case, which was traced to a California store and a woman who said she bought the watch for Condit as a gift.

"It may seem at first glance it doesn't have anything to do with this case but in fact has everything to do with this case, because it, again, it involves conduct certainly unbecoming a member of Congress ... and perhaps is part of a pattern of obstructive behavior," DiGenova said.

In other developments, the management of the apartment building where Levy lived sent a memo Friday to residents, asking them to cooperate with police in the investigation.

Last month, police asked the front desk clerks to describe what they saw at the building in the days leading up to Levy's disappearance.

Police combed through several city parks last week, including Rock Creek Park near Levy's apartment, but reported finding no clues. The search is expected to resume Monday.

Sen. Joseph Lieberman, D-Connecticut, said it wouldn't be productive to focus on Condit's conduct. In 1998, Lieberman was the first prominent Democrat to criticize Clinton for his affair with Monica Lewinsky.

Lieberman said the two matters are different and he declined to say whether Condit should resign, as two Republican lawmakers have said.

"The Chandra Levy case is a missing persons case. And I think we all ought to let the law-enforcement authorities focus on finding Chandra Levy and relieving the terrible trauma and nightmare that her family and friends have gone through," Lieberman told Fox News Sunday. "And when that is over, politicians can begin to speak out."

Saturday, a spokeswoman for Vice President Dick Cheney, said Cheney met with Condit around the same time Levy was logging off her computer in her apartment May 1.

Juleanna Glover Weiss said the meeting happened between 12:30 p.m. and 12:50 p.m. in Cheney's office in the House of Representatives. The meeting was "at Condit's request," she said, and included Cheney and some of Cheney's staff discussing the California energy crisis.

Glover Weiss described it as a typical meeting.

CNN has also learned Condit voted on the House floor the evening of May 1, at 6:25 p.m. and 6:35 p.m.
