Rivero Blew $626K on Bets, Bilked Clients

NEWARK, N.J. – Mario E. Rivero Jr., 39, of Elizabeth, New Jersey, isn’t just managing money anymore. He’s admitting to stealing over $600,000 from the very people who trusted him with it. The former investment advisor pleaded guilty on February 2, 2023, to charges of wire fraud and securities fraud, a courtroom confession that brings a years-long scheme into the harsh light of day.

According to federal prosecutors, Rivero, while employed by a large brokerage firm between April 2018 and November 2020, systematically pilfered $626,478 from five unsuspecting clients. This wasn’t a matter of bad investments; it was a calculated betrayal. Rivero promised to invest the funds responsibly, but instead diverted the cash to fuel a personal spending spree and, crucially, a gambling addiction. The details paint a picture of a man prioritizing high-stakes bets over his fiduciary duty.

The scheme was simple in its audacity. Rivero obtained client money under the guise of legitimate investment, then unlawfully transferred it for his own enrichment. He didn’t just dip into the funds; he allegedly used the money to fund a lifestyle beyond his means. The U.S. Attorney’s Office, led by Philip R. Sellinger, isn’t pulling punches, describing the actions as a deliberate effort to defraud multiple clients.

Each count of wire fraud and securities fraud carries a significant penalty. Rivero is facing a maximum potential sentence of 20 years in prison for each charge, alongside maximum fines of $1 million for wire fraud and $5 million for securities fraud. This isn’t a slap on the wrist; it’s a serious reckoning for a breach of trust that left victims financially vulnerable.

The investigation, which led to Rivero’s guilty plea, was a joint effort by the FBI, under the direction of Special Agent in Charge James E. Dennehy, and postal inspectors from the U.S. Postal Inspection Service, led by Inspector in Charge Christopher Nielsen. These agencies worked diligently to unravel the financial web Rivero had spun, bringing the truth to light.

Assistant U.S. Attorney Shawn Barnes, Chief of the OCDETF/Narcotics Unit in Newark, is prosecuting the case. Rivero’s sentencing is currently scheduled for June 27, 2023. While a plea is not an admission of guilt, it signals a likely path toward conviction and a substantial prison sentence for a man who traded his clients’ financial security for a gamble.
