The e-mail and others between Andrea McNulty and Guy Hyder, chief of security at Harrah's Lake Tahoe, were included in the motion filed late Tuesday in Washoe District Court in Reno.

In one e-mail to Hyder, McNulty apparently spoofed a memo from Harrah's President John Koster to staff, announcing her immediate resignation.
"She is with Big Bens child and ... she has relocated to Pittsburgh," the e-mail said. "We wish her good luck [she will need it] in her future endeavors."
McNulty's lawyer did not immediately return calls for comment Wednesday evening.
McNulty, a VIP casino hostess, filed the civil suit against Roethlisberger in July, claiming the Super Bowl-winning quarterback raped her in 2008 in a hotel penthouse across the street from a golf course where he was playing in a celebrity tournament.
Roethlisberger and his lawyers deny McNulty's allegations, and last week accused her in court documents of fabricating the assault to extort a big payoff from him.
McNulty said she reported the incident to Harrah's security but never filed a criminal complaint because she feared Harrah's would side with Roethlisberger and she would be fired. She also accused Harrah's officials of orchestrating a cover-up.
The suit seeks a minimum of $440,000 in damages from Roethlisberger, at least $50,000 in damages from the eight Harrah's officials named as defendants and an unspecified amount of punitive damages.
In the motion to dismiss, Margo Piscevich, attorney for several casino workers, including Hyder, said McNulty kept the casino security chief "informed with running e-mail commentary about her plan to have sex with Roethlisberger."
"Hyder did not report it to management, since having consensual sex with a hotel patron, while on the job, would get her fired," the motion said.
It added that her suit "is cloaked in a media-attention-getting, sensationalized and inflammatory pleading" that lacks any legal basis against the casino workers.
McNulty alleges Roethlisberger assaulted her after she went to his room to fix his television.
In another e-mail exchange with Hyder, she reportedly wrote, "Hail Mary full of grace give me the strength to not go to his room to fix his television."
