Six years ago Thursday Bernard Madoff was arrested in what investigators discovered to be the largest Ponzi scheme in American history, one that stole more than $18 billion from investors across the country. While Madoff was given to what amounts to a life sentence in 2009, the Department of Justice is still handing down punishments to several of those associated with the scheme. The latest group of ex-Madoff employees received sentences just this week, while another former insider will hear her sentence on Dec. 15.

One of Madoff's former accountants, David Friehling pleaded guilty in November 2009 to nine counts, including filing false audit reports, investment adviser fraud, and obstructing the administration of internal revenue laws. Friehling is scheduled to be sentenced on July 10, 2015, and faces a maximum sentence of over 100 years in prison.

Frank DiPascali spent 33 years as Madoff's right-hand man, ultimately rising to the position of chief financial officer at the swindler's firm. He pleaded guilty in 2009 to 10 counts related to fraud in exchange He pleaded guilty in 2009 to 10 counts related to fraud, agreeing to cooperate with prosecutors in the investigation in hope of a lighter sentence. Currently on house arrest and under a $170 billion forfeiture order, DiPascali's sentencing deadline is set for May 2015, when he faces a maximum of 125 years in prison.

Daniel Bonventre, one of Madoff's longest-serving aides, received a 10-year sentence for his work as an accountant and former head of operations. Prosecutors had asked for at least 20 years in prison for the 67-year-old Bonventre, who began working for Madoff in the 1960s.

Annette Bongiorno, Madoff's former secretary, was sentenced to six years in prison on Dec. 9. Bongiorno began working for Madoff as a 19-year-old, a fact that defense lawyers highlighted as they argued that Bongiorno had no education in the industry outside of her work for the con man.

Jerome O'Hara received a two-and-a-half year prison sentence for conspiracy and fraud on Dec. 9 for his work as a computer programmer for Madoff. The sentence was significantly short of what prosecutors had asked for, but Judge Laura Taylor Swain agreed with defense attorneys who claimed that O'Hara had been misled and used by Madoff.

Like O'Hara, George Perez was a computer programmer for Madoff's bogus investment firm and received a similar two-and-a-half year prison sentence on conspiracy and fraud charges a day after his former colleague.

Joann Crupi managed accounts for Madoff and was found guilty in March along with O'Hara, Perez, Bonventre, and Bongiorno on charges of conspiracy and fraud. Her sentence, scheduled for Dec. 15, will be announced last of the five recently convicted Madoff aides.

Peter Madoff worked as the chief compliance officer for his brother's company for over 40 years. He pleaded guilty to fraud and conspiracy charges in June 2012 and received a $143 billion forfeiture order along with a 10-year prison sentence.

Paul Konigsberg pleaded guilty to fraud charges and agreed to a forfeiture order of $4.4 million. The former accountant is set to be sentenced in March 2015, facing up to 30 years in prison and millions of dollars in additional fines and penalties.

Craig Kugel pleaded guilty to conspiracy charges in June 2012 after working as an administrator at Madoff's firm. He faces at least $2.3 million in forfeiture, and his sentencing date is set for March 2015. He is the son of David Kugel, a former Madoff trader.

David Kugel, a former trader for Madoff's firm, pleaded guilty in November 2011 to fraud charges. He faces a maximum prison term of up to 85 years in prison and fines of close to $12 million when he is sentenced in March 2015, along with his son Craig Kugel.

Eric Lipkin pleaded guilty to fraud and conspiracy charges in 2011 and agreed to a forfeiture of $1.4 million in exchange for cooperation with authorities. His sentencing is scheduled for March 2015, when he could face up to 70 years in prison. He is the son of Irwin Lipkin, Madoff's first hire and longtime employee.

Known as Madoff's first hire at the firm, Irwin Lipkin pleaded guilty to fraud, conspiracy, and falsifying documents in November 2012. Currently out on bail, he is set to be sentenced in April 2015. He is the father of another Madoff insider, Eric Lipkin.
