Renowned opera star Placido Domingo, who last month was accused of sexual harassment by almost a dozen women, became the focus of a new round of accusations on Thursday, when a woman who teaches voice at Texas Christian University added her name to the list of those who say he harassed them.

Her name is Angela Turner Wilson. She's the daughter of R. Gerald Turner, the president of Southern Methodist University and the sister of local actress Jessica D. Turner.

Reached Thursday night, the SMU president said he and his wife "aren't commenting, but we are obviously very proud of Angela."

In related news, the Dallas Opera announced Thursday that it's officially canceling its March 11 gala, in which Domingo was scheduled to perform. The announcement cited "ongoing developments regarding allegations made against" Domingo.

In 1961, Domingo made his U.S. operatic debut at the Dallas Civic Opera, singing the role of Arturo with Joan Sutherland in Lucia di Lammermoor. The March 2020 performance would have been the first time since that performance that Domingo would have sung with the Dallas Opera.

But at the moment, he's facing a firestorm.

In a story released by the Associated Press on Thursday, Wilson said Domingo's harassment of her occurred during the Washington Opera's 1999-2000 season. The opera was Jules Massenet's Le Cid, about a legendary Spanish conqueror, starring Domingo, who then served as the company's artistic director.

The AP story notes that the opera, being filmed for broadcast on public television, was a career break for Wilson, then 28, who'd been cast as the second female lead. Having been lauded in reviews, "I knew this was the start of big things for me," she told the AP.

One evening before a performance, she told the AP, she and Domingo were having their makeup done together when he rose from his chair, stood behind her and put his hands on her shoulders. As she looked at him in the mirror, he suddenly slipped his hands under her bra straps, she said, then reached down into her robe and grabbed her bare breast.

"It hurt," Wilson told the AP. "It was not gentle. He groped me hard." She said Domingo then turned and walked away, leaving her "stunned and humiliated."

In a 2006 interview with the Kansas City Star, Wilson said she made her operatic debut at age 12, appearing in Albert Herring at the University of Oklahoma. She cited as her "big opera moment" singing Le Cid at the Washington Opera with Domingo, about whom she said, "It's like standing next to a force of nature."

Wilson also listed her film credits, which include Miss Firecracker, in which she appeared with Tim Robbins and Holly Hunter. She listed her "favorite movie-star moment" as "talking about religion with Tim Robbins during Firecracker filming."

Now 48, Wilson is one of 11 women to have come forward after the initial AP story, in which numerous women accused the long-married, Spanish-born superstar of sexual harassment or inappropriate, sexually charged behavior, and of sometimes damaging their careers if they rejected him.

In the weeks since the story was published, the women have shared new stories about encounters with Domingo, who is currently general director of the Los Angeles Opera. Their accusations cover charges, as the AP story noted, of unwanted touching, persistent requests for private get-togethers, late-night phone calls and sudden attempts to kiss them on the lips.

Wilson could not be reached by The Dallas Morning News on Thursday.

Domingo's spokeswoman recently issued a statement disputing the allegations but provided no specifics.

"The ongoing campaign by the AP to denigrate Placido Domingo is not only inaccurate but unethical. These new claims are riddled with inconsistencies and, as with the first story, in many ways, simply incorrect," spokeswoman Nancy Seltzer said. "Due to an ongoing investigation, we will not comment on specifics, but we strongly dispute the misleading picture that the AP is attempting to paint of Mr. Domingo."

The AP obtained a copy of an email sent Thursday to LA Opera employees saying that administrators, who hired outside counsel to investigate after the initial accusations, "are very troubled by the ongoing allegations raised by the Associated Press, and take them very seriously." The email noted that Domingo would not be involved in day-to-day management until the investigation concluded and asked employees not to comment publicly.

Washington National Opera issued a statement saying it was "disturbed and disheartened" by the new allegations, but did not say whether it planned to investigate them.

Wilson said she chose to come forward after the 78-year-old Domingo's reaction to the AP's initial story, in which he said he believed his actions "were always welcomed and consensual" and added that "the rules and standards by which we are — and should be — measured against today are very different than they were in the past."

The AP quoted Wilson as saying that she rejects the idea that such behavior has ever been acceptable.

"What woman would ever want him to grab their breast? And it hurt," she said. "Then I had to go on stage and act like I was in love with him."
