RENO, Nev. (AP) — Law enforcement officials in Nevada have no intention of opening a criminal investigation into allegations that Pittsburgh Steelers quarterback Ben Roethlisberger raped a woman at a Lake Tahoe hotel-casino a year ago, the sheriff’s department said Wednesday. Douglas County Sheriff’s Deputy Teresa Duffy said the accuser would have to file a criminal complaint to trigger an investigation into the incident the woman says occurred during a celebrity golf tournament last July while she was working as an executive VIP casino host at Harrah’s Lake Tahoe. “The victim is the only one who can do that,” Duffy told The Associated Press. “Unless there was a third party that actually witnessed the incident, which according to the civil case, was not the case here.” The 31-year-old Nevada woman has filed a lawsuit saying the Super Bowl winning quarterback raped her in a hotel penthouse across the street from the golf course, a claim his lawyer vehemently denies. She also accuses Harrah’s officials, including the casino’s chief of security, of orchestrating a cover-up of the incident she says she reported to him the next day. The lawsuit alleges Harrah’s officials worked to silence her and undermine her credibility rather than investigate her claims. The woman, a native of Canada who had worked at Harrah’s Lake Tahoe hotel-casino since 2003, never went to outside authorities with her story, and it’s unclear why she decided to file the lawsuit seeking hundreds of thousands of dollars a year after the alleged incident. Her lawsuit says she didn’t file a criminal complaint because she feared Harrah’s would side with Roethlisberger — a friend of the hotel-casino’s regional president John Koster — and she would be fired. She said the security chief, Guy Hyder, told her she was “over reacting,” that “most girls would feel lucky to get to have sex with someone like Ben Roethlisberger” and that “Koster would love you even more if he knew about this.” The lawsuit said she was treated between last August and December at five different hospitals for depression and anxiety stemming from the alleged assault, and returned to work each time after treatment.
