Condit faces second interview on missing intern

Condit denies having had a romantic relationship with Chandra Levy.

WASHINGTON (CNN) -- District police plan Wednesday evening to interview Rep. Gary Condit, D-California, for the second time about missing intern Chandra Levy, Executive Assistant Police Chief Terry Gainer told reporters Wednesday afternoon.

Gainer would not disclose the focus of the second interview. Police initially interviewed the congressman soon after Levy's April 30 disappearance.

"It's not unusual that we would go back and re-interview witnesses," Gainer said. "When you talk to people in the first few days, you have a different set of information than you have nearly 90 days later. So we have more questions we want to ask."

Gainer said Condit has "been cooperative" during the search and said police were "looking forward" to the interview.

Chandra Levy has not been reported seen since April 30.

"It may very well lend something to her state of mind, because clearly they had some type of relationship and it keeps shifting a little bit over time," said Gainer. "But I do believe he and others know how she lived and what she was thinking about when she was here."

Levy's parents returned to Washington Tuesday night primarily to meet with their newly hired lawyer, Billy Martin, they said.

Martin told reporters Wednesday he hoped to have a "team of investigators" and a "full investigation." He said he had been retained "to assist the family, Dr. and Mrs. Levy, in trying to locate or find information on their daughter."

Levy's parents spoke on camera last week from their Modesto, California, home.

Martin had been in Cincinnati representing the city in a probe by the U.S. Justice Department of recent community unrest.

Condit has acknowledged through a lawyer and his spokesmen that he was a friend of Levy, 24, who was last seen April 30 at a Washington gym. She had just completed an internship at the Federal Bureau of Prisons and was preparing to return to her family's home in Modesto, California, for her college graduation.

In a brief phone call to Levy's parents last weekend, Condit directly denied any romantic involvement, according to a spokesman. The congressman telephoned the Levys following their comments last week that Condit should reveal what he might know about their daughter's disappearance.

Martin told CNN the Levys retained him because "they wanted someone to investigate who understands these matters, who will hopefully get answers." He would not comment about Condit.

Before he went into private practice, Martin was an assistant U.S. attorney and headed a homicide investigations unit. As a private attorney, he gained prominence when he represented Marcia Lewis, Monica Lewinsky's mother, during a federal grand jury investigation into Lewinsky's relationship with President Clinton.
