Ms. Dunne said that she first met Mr. Lubin when she was touring New England with Circus Smirkus, a youth troupe that Mr. Lubin helped coach as recently as last summer. (Circus Smirkus also runs a summer camp; Mr. Lubin never taught there.)

She gave the following account:

During Big Apple’s 2004 New York season, Mr. Lubin contacted her and offered her work with Big Apple’s mini-troupe for hire. Ms. Dunne, then known as Zoey Phillips, had dreamed of a circus career. She was thrilled.

“All I can remember is feeling that it was like this great mentorship opportunity,” she said.

But first, Mr. Lubin told her, he had another job for her: modeling, for what he described as his personal photography business.

She came to Lincoln Center, and he escorted her to his trailer.

The photos, Mr. Lubin explained, were for a Japanese paint-on tattoo company. First, he had her lie on a bed in a bathing suit and pretend to be sleeping. Then he showed her photos of her favorite actor, Ashton Kutcher, and told her to imagine getting ready for a date with him and to think about how excited she would feel.

“I felt overwhelmingly sad, not excited,” Ms. Dunne recalled.

Mr. Lubin told her to take off her underwear. She declined, saying she was uncomfortable.
