The former business manager of Alanis Morissette was sent to six years in prison after he admitted to swindling the singer.

Jonathan Schawartz had worked for Morissette for a number of years while he was under employment of a Los-Angeles area firm called GSO Business Management. He had admitted to stealing millions from the singer by misleading her about her finances. Since Morissette trusted him, she never questioned or double checked his claims.

After the hearing concluded, Schwartz was ordered to pay $8,657,268 in restitution, according to a federal judge´s sentence announced late Wednesday. In addition to the fine, he also has to spend six years behind bars.

Morissette, attending the sentencing hearing, said Schwartz acted in a “long, drawn-out, calculated and sinister manner,” and shattered her dreams of being able to focus on her family and causes.

Schwartz admitted to stealing $4.8 million from the rock singer between 2010 and 2014. He would classify the withdrawals as the singer’s personal expenses and would keep her under the impression that she is in a sound financial position.

When questioned, Schwartz accepted that he lied by telling Morissette that he was investing her money in the newly emerging marijuana business.

During the hearing, the accountant also admitted stealing $1 million from another client on the false pretext of home renovations as well as $737,500 from another customer whose signature he forged on receipts.

Deirdre Fike, the assistant director of the FBI´s Los Angeles field office, said that cons like Schwartz should be punished hard so that they can learn a lesson. “Individuals have a right to feel secure when placing their trust, as well as large sums of money, with financial managers,” she said in a statement.

Morissette won fame at an early age. When her 1995 album “Jagged Little Pill” won the Grammy for Album of the Year, she was 21 and the youngest artist ever to win the prestigious award.
