"Dozens of individuals involved in a nationwide conspiracy that facilitated cheating on college entrance exams and the admission of students to elite universities as purported athletic recruits were arrested by federal agents in multiple states and charged in documents unsealed on March 12, 2019, in federal court in Boston", the release says.
"Some simply never showed up" to play, Lelling said of the students.
Loughlin's fashion designer husband Mossimo Giannulli was also on the list, while Huffman's husband William Macy, the star of Showtime's "Shameless", was not, despite the indictment making clear he was partly involved in talks with Singer's operations.
Loughlin, best known for her role in the sitcom Full House and the recent Netflix sequel Fuller House, is married to clothing company founder Mossimo Giannulli, who was also charged in the scheme.
"In many instances, the students taking the exams were unaware that their parents had arranged for this cheating", the Federal Bureau of Investigation said. In exchange, Huffman, a "Desperate Housewives" cast member, was directed to bring her daughter to a "controlled" SAT testing center where someone corrected her answers or gave her assistance during the test, the documents say. "They got Aunt Becky out here getting cuffed by the feds", said another user.
Representatives for Loughlin and Giannulli, did not immediately respond to requests for comment.
He called it the biggest college admissions scam ever prosecuted by the U.S. Justice Department.

"I am responsible. I put all the people in people", Singer told the court on Tuesday, according to MassLive.
Heinel has also been indicted on charges of racketeering conspiracy and is accused of accepting money to get numerous kids into the California college as athletes.
The documents allege that some of the defendants actually "created fake athletic profiles for students to make them appear to be successful athletes".
Three other cooperating witnesses, including a former head coach of women's soccer at Yale, have agreed to plead guilty, prosecutors said.
