Laguna Niguel, California — A former Southern California investment firm CEO has been sentenced to nearly three years in federal prison after defrauding more than 400 investors of approximately $63 million through a scheme involving promises of steady returns and supposedly diversified investments.
Marco Giovanni Santarelli, 57, of Laguna Niguel, founded and led Norada Capital Management (NCM), a private equity fund based in the Orange County community. Prosecutors said he solicited investments through unsecured promissory notes while presenting the opportunity as a source of predictable income.
On October 15, 2026, Santarelli was sentenced to 33 months in prison and ordered to pay $63,165,357 in restitution to victims. He had pleaded guilty to one count of wire fraud in October 2025.
How the $63 Million Investment Fraud Scheme Worked
According to the U.S. Attorney’s Office, the scheme operated from June 2020 through June 2024. During that period, Santarelli solicited investments from hundreds of people across the United States.
Investors were asked to purchase unsecured promissory notes ranging from $25,000 to $500,000. Santarelli allegedly promised returns of approximately 12% to 17% through monthly interest payments over periods of three to seven years.
He represented that the money would be invested in several areas, including e-commerce, real estate, Broadway shows and cryptocurrency.
Court documents described how Santarelli presented the investment opportunity as relatively straightforward for people seeking income without actively managing their money.
“Santarelli promised that the notes were backed by diversified assets under management and offered steady, predictable monthly returns,” court documents said. “He further promised that NCM was to be a ‘hands-off passive investment,’ perfect for retirement funds.”
These representations helped present the investments as an opportunity for people seeking regular income, including those planning for retirement.
Prosecutors Say Financial Records Hid More Than $90 Million in Debt
The investment arrangement allegedly differed significantly from what investors had been told.
Prosecutors said the money was directed toward risky assets that generated little or no profit. As the business accumulated debt, Santarelli allegedly provided investors with balance sheets that concealed the company’s financial problems.
According to prosecutors, those records hid more than $90 million in debt and included inflated asset figures.
The alleged discrepancies meant investors were not receiving an accurate picture of the fund’s financial condition.
Prosecutors also said Santarelli used money from newer investors to make interest payments to existing investors, a practice associated with Ponzi schemes.
“In Ponzi-scheme fashion, Santarelli made interest payments to investors using other investors’ money,” prosecutors said.
Such payments can create the appearance that an investment is generating income even when the underlying business is not producing sufficient profits to support the promised returns.
More Than 400 Investors Lost Approximately $63 Million
The scheme resulted in substantial financial losses for investors, according to federal authorities.
Prosecutors said Santarelli caused more than 400 investors to lose approximately $63 million. The losses affected people who had entrusted money to the fund based on promises of regular payments and diversified investments.
The case also highlights the risks associated with investments that promise unusually high, consistent returns while providing limited transparency into the underlying assets and financial position.
An unsecured promissory note generally does not provide the same collateral protection as a secured debt instrument. Investors may face significant difficulties recovering their money if the borrower cannot repay the debt.
Santarelli pleaded guilty to wire fraud in October 2025, acknowledging criminal responsibility through his guilty plea.
Federal Investigation Leads to Prison Sentence
The investigation involved several federal agencies. Homeland Security and the Federal Bureau of Investigation investigated the case, with assistance from the U.S. Securities and Exchange Commission.

Chief Assistant U.S. Attorney Jennifer L. Waier prosecuted the case.
The sentence includes 33 months of imprisonment and a restitution order requiring Santarelli to pay $63,165,357 to compensate victims for their losses.
Restitution is intended to help victims recover money lost through criminal conduct. However, the amount ordered does not necessarily mean that every victim will immediately receive full repayment; actual recovery can depend on the defendant’s available assets and other factors.
What Investors Can Learn From the Case
The case underscores the importance of independently evaluating investment opportunities, particularly those advertising high returns with little apparent risk or effort.
Investors can reduce uncertainty by examining how a fund generates its income, reviewing financial statements, verifying claims about assets and understanding whether an investment is secured by collateral.
Promises of consistent double-digit returns deserve careful scrutiny, especially when an investment is described as a hands-off source of retirement income.
The case against Santarelli demonstrates how misleading financial representations and the use of new investors’ money to pay existing investors can result in serious criminal consequences and substantial losses.
