Prosecutors said that the daughter, whom they called Yale Applicant 1 in court documents, was admitted to Yale as a recruit for the women’s soccer team, despite not being a competitive soccer player. According to documents charging Rudolph Meredith, the former women’s soccer coach at Yale, Mr. Singer had paid Mr. Meredith a bribe to designate the young woman as a recruit for the team. Mr. Singer has pleaded guilty to racketeering and other charges, and Mr. Meredith has pleaded guilty to fraud and conspiracy charges.

On Friday, Yale Applicant 1 was finally identified: She is Sherry Guo, a young woman from China who moved to Southern California for high school, and who was a freshman at Yale until last month, according to her lawyer, James Spertus.

Ms. Guo’s identity was first reported on Friday by The Wall Street Journal.

A spokeswoman for the United States attorney’s office in Boston, Christina Sterling, declined to comment on Ms. Guo’s case. Asked why Ms. Guo and her parents — as well as the still unidentified family that was said to have paid Mr. Singer $6.5 million — have not been charged in the case, she said, “I cannot comment other than to say it is an ongoing investigation.”

According to the charges against Mr. Meredith, Ms. Guo and her family were introduced to Mr. Singer in 2017 by a financial adviser based in Los Angeles. An employee of the financial adviser sent Mr. Singer an email “stating that Yale Applicant 1’s father wished to make a ‘donation’ to ‘one of those top schools for his daughter’s ‘application,’” the charging documents said.

Mr. Singer promptly sent Ms. Guo’s résumé and personal statement to Mr. Meredith, the soccer coach, according to the charging documents. Her personal statement contained links to her art portfolio; Mr. Singer told Mr. Meredith he would “revise” the materials to “soccer.” A few days later, he sent Mr. Meredith an athletic profile that falsely described Ms. Guo as the co-captain of a prominent club soccer team in Southern California. Mr. Meredith then designated her as a recruit for the soccer team.
