NEW YORK — Manhattan prosecutors will meet today with Dominique Strauss-Kahn’s defense lawyers who are pushing for sexual assault charges against him to be immediately dropped, a person familiar with the case told The Associated Press.

Just a few weeks ago, the case against Strauss-Kahn looked iron-clad.

Physical evidence linked the former International Monetary Fund leader to the hotel maid accusing him of sexual assault. Her version of events was unwavering, and police and prosecutors called her credible.

Now, prosecutors are rethinking whether they can even go forward with the case after finding that Strauss-Kahn’s accuser wasn’t truthful about her background and the aftermath of the alleged attack. But they haven’t questioned her account of the encounter itself, at least publicly.

The details sketch out a legal conundrum: prosecutors who may still have faith in the accusation but not in the accuser’s prospects of helping them prove it.

The Manhattan district attorney’s office on Tuesday would say only that it was still investigating and had made no decisions about what to do. The charges, which include attempted rape, have not been dropped.

Authorities haven’t concluded that no attack happened, but amid the revelations about the accuser’s past lies, “the details are a bit more in doubt,” said a law enforcement official.

Strauss-Kahn, meanwhile, has zero incentive to agree to a plea deal. His attorneys have said they would be able to prove the encounter was not forcible.
