Local criminal lawyers, who were not involved in the case, speculated that Krischer was being cautious or that the alleged victims had credibility issues that would come up at trial.
"I assume these women had serious holes in their stories," said Richard Tendler, a Palm Beach criminal defense lawyer.
The Associated Press reported that Epstein's attorneys, including Harvard professor Alan Dershowitz, presented prosecutors with evidence that some of the girls had criminal records and issues with drugs and alcohol. Lawyers claimed that at least one of the girls was older than 18, the agency reported. Dershowitz did not return a call for comment.
The grand jury indicted Epstein in July 2006 on one count of felony solicitation of a prostitute. That charge does not require him to register as a sex offender.
Police at the time said they had enough evidence to charge Epstein with more serious sex offenses, prompting criticism that the reportedly reclusive financier, who once counted among his friends Clinton and Donald Trump, was getting preferential treatment.
Police Chief Michael Reiter, in a May 2006 letter to Krischer, called Krischer's handling of the case "highly unusual" and asked him to disqualify himself from the case. He also referred the case to the FBI to see whether Epstein may have violated federal law.
Howard Rubenstein, Epstein's spokesman, said Epstein had no comment. He declined to discuss the case.
