A former sailing head coach at Stanford avoided prison time when a judge sentenced him Wednesday for his role in a sweeping college admissions scam at elite U.S. universities.

John Vandemoer is the first person to be sentenced in the case that exposed the lengths that some wealthy parents will go to get their children into the country's top schools.

Vandemoer admitted to agreeing to help students get into the prestigious university as recruited athletes in exchange for money for his sailing program. He told reporters that he believed at the time he was helping his team but now sees his actions were wrong.

“A big part of my coaching philosophy has always been it’s not the mistake that defines you but rather it’s what you do afterward. I’m holding true to those words now,” Vandemoer said outside the federal courthouse in Boston.

U.S. District Judge Rya Zobel sentenced him to one day in prison, which he was deemed to have served. He will pay a 10,000-U.S.-dollar fine and serve two years of supervised release, including six months of home confinement with electronic monitoring.

Zobel said she believed Vandemoer should be punished because “it’s too easy to do this kind of thing.” But she said she was swayed by the powerful letters of support he received and called him probably the “least culpable” of those charged in the case because he didn’t take any of the money for himself.

Assistant U.S. Attorney Eric Rosen urged the judge to sentence Vandemoer to more than a year in prison to send a message to others charged in the case and people considering cheating the college admissions system, which he said is “crying out for reform.”

“If we fail to take these crimes seriously, if you give just a slap on the wrist instead of real punishment. ... We are short changing not only the criminal justice system, but all those kids in high school who are working hard every day in an effort to improve their own lives and to get into the best school they can honestly and through hard work,” Rosen said.

Vandemoer pleaded guilty in March on the same day that charges were announced in the so-called “Operation Varsity Blues” case against 50 people, including business executives and Hollywood actresses. Wealthy parents charged include actresses Felicity Huffman and Lori Loughlin as well as Loughlin’s fashion designer husband, Mossimo Giannulli.

Vandemoer stood briefly in court and apologized to his family, friends, the sailing team and Stanford.

His lawyer asked for probation, noting that all the money Vandemoer took went to Stanford’s sailing program while other coaches charged in the case are accused of personally profiting off the bribes. Vandemoer has already suffered through the loss of his job and housing, attorney Robert Fisher said.

“His life has been essentially turned upside down,” Fisher said.

The admissions that consultant at the center of the scheme, Rick Singer, tried to get a student from China into Stanford through Vandemoer’s sailing program in 2016, authorities say. It was too late to secure a spot for the student as a recruit, but the student got in through the normal process, authorities say.

After the student was admitted, Singer gave 500,000 U.S. dollars to Vandemoer’s program to secure his help with future applicants, prosecutors say. Stanford has since expelled that student.

Vandemoer also got 110,000 U.S. dollars for the sailing program from Singer last year in exchange for labeling a prospective student as a recruit, prosecutors say. The student ended up going to another school.

He later agreed to help another student get in as a recruit in exchange for 500,000 U.S. dollars, prosecutors say. The student also went to another school, but Singer – who was cooperating with authorities by this point – sent 160,000 U.S. dollars to the sailing program anyway.

Debra Zumwalt, Stanford vice president and general counsel, said in a letter filed in court that it views the 770,000 U.S. dollars it received from Singer’s sham foundation as “tainted” and is trying to determine “an appropriate way for those funds to be used for the public good.”

Several other coaches have also admitted to charges in the case, including Yale women’s soccer coach Rudy Meredith, who is scheduled to be sentenced next week. Other coaches, such as former Georgetown University tennis coach Gordon Ernst, have pleaded not guilty.

Huffman is among 14 parents who have agreed to plead guilty. The “Desperate Housewives” star has apologized for paying 15,000 U.S. dollars to have someone rig her daughter’s SAT score and is scheduled to be sentenced in September.

Loughlin and Giannulli, who are charged with paying 500,000 U.S. dollars to get their two daughters into the University of Southern California as crew recruits, are fighting the charges. They haven’t publicly commented on the allegations.
