Chrissy Mazzeo's lawsuit, filed Wednesday, names several other defendants, the Las Vegas Review-Journal reported. They include Sig Rogich, a political consultant; the Las Vegas police; former Sheriff Bill Young; Don Campbell, a lawyer; and Pennie Mossett-Puhek, a sometime friend of Mazzeo.
Mazzeo claims that Gibbons offered to walk her to her car after an evening of drinking with Rogich and Mossett-Puhek. She says that he attacked her in the garage
The district attorney eventually dismissed the case for lack of evidence.
Mazzeo claims that the attack and the aftermath forced her to move out of Las Vegas to California.
"You see how many ways you get screwed," she said of the case. "My whole thing was, as long as you tell the truth, it will always come out. But it doesn't seem like it worked out that way."
Gibbons, a Republican who was in Washington on Thursday, told the newspaper that he denies the charges. He accused Mazzeo of abusing the legal system.
