"In what was the biggest mistake of my life, I put my trust with Bernard Madoff," Friehling told a judge.
Friehling has yet to be sentenced, as he is continuing to work with prosecutors. He pleaded guilty to charges that carry a potential prison term of up to 114 years in prison, though substantial cooperation can result in significant leniency. He also agreed to forfeit $3.1 million, which represents what he was paid by Madoff for his accounting and tax services, along with what his family withdrew from their Madoff accounts.
Jeremy Friehling was "a friend to many and a brilliant student who gave selflessly of his time to tutor other students," said a statement from the dean of the Ohio State medical school, Charles Lockwood. He also said Friehling had great promise as a future physician.
