A Long Island escort is claiming that she had "rough sex" with disgraced former police chief James Burke in Oak Beach.

Oak Beach is where another escort, Shannon Gilbert, was found dead in 2010 after allegedly being hired by an Oak Beach resident. Her disappearance triggered the search leading to the discovery of 10 Gilgo Beach victims, and then Gilbert's body.

The escort, who only identified herself as Leanne, says she attended two parties in Oak Beach with Burke in 2011. She says at that second party, she had sex for money with Burke.

"He was frustrated because he could not consummate the act," says Leanne. "He began to get really aggressive, and he used the term, that I was not a good whore."

Leanne was flanked at a news conference by her attorney John Ray, who is also the attorney for Shannon Gilbert's estate. He says Burke's alleged actions suggest an "arrogance and a certainty that he could do pretty much whatever he wanted with regard to the [Gilgo Beach] investigation."

In a statement, an attorney for Burke said, "Any credible witness and any credible information should be provided to the proper law enforcement officials and not done via a press conference. All of the allegations raised today are false and slanderous."

Leanne said that she decided to come forward five years after the alleged encounter because she thinks she could have been one of the victims found along Ocean Parkway.

"It's very clear [the Suffolk Police Department is] hiding something," says Leanne. "They can't clear the case without recusing themselves from any responsibility."

Leanne and Ray acknowledged there is no physical proof of the alleged encounter, but she said she's willing to take a lie detector test.

Burke is currently in federal prison and appealing his sentence for violating a suspect's civil rights and then covering it up.
