Former Morgan Stanley Financial Advisor Sentenced to Prison for Defrauding His Elderly Client

TUCSON, Ariz. – Ronald Diaz, age 41, of Tucson, was sentenced on Tuesday by United States District Judge Scott H. Rash to 22 months in prison. Diaz pleaded guilty to Wire Fraud on July 18, 2024.

While working as a financial advisor, Diaz engaged in a scheme to defraud one of his elderly clients. To induce the victim into the scheme, Diaz falsely represented an investment opportunity in an “annuity” that “guaranteed” a 10% return. Between November 2020 and July 2022, to disguise his scheme, Diaz directed the victim to transfer $970,000 to Diaz’s family members. Diaz then instructed his family to distribute most of the victim’s funds back to Diaz. Diaz used large portions of the victim’s money for his own personal use including: (1) gambling at casinos; (2) a down payment for a 2021 Range Rover; (3) payments for credit card debt; (4) to remodel Diaz’s family pool; (5) mortgage payments; and (6) other personal expenses. Diaz made some “interest” payments to entice the victim into providing additional money throughout the scheme. None of the victim’s money was used towards any legitimate investment. During the investigation of the case, the victim passed away. As part of his sentence, Diaz was ordered to pay the victim’s next of kin $867,510.37 for the loss the victim suffered as a result of the scheme. 

The Federal Bureau of Investigation conducted the investigation in this case. The United States Attorney’s Office, District of Arizona, Tucson, handled the prosecution.
