A federal judge has sentenced a Mesa woman to four years in prison after a jury found her guilty of stealing more than half a million dollars from a bank branch she once managed. Brooke McDonough, 35, was convicted of embezzlement by a bank employee and transactional money laundering, charges that stem from an investigation into missing cash at the East Valley branch where she worked.

Prosecutors laid out a case that described a months-long scheme in which McDonough removed cash from automated teller machines and from the branch vault. Authorities said she concealed the shortfalls by altering or manipulating the branch’s monthly audits, allowing the cash shortages to go unnoticed while she continued to withdraw funds. The pattern of withdrawals and the steps taken to mask them formed the basis of the federal charges that led to her conviction.
A stack of $100 bills, illustrating the $655,000 prosecutors say a former Mesa bank manager embezzled.
The theft came to light after McDonough resigned from her position and the bank conducted an internal investigation. That probe identified the missing funds and prompted referral to federal authorities. Prosecutors said McDonough had deposited the bulk of the cash into her personal bank accounts, a point that factored into the money laundering charge alongside the embezzlement count.
In addition to the prison term, the court ordered McDonough to pay $655,000 in restitution — effectively the full amount prosecutors say was taken from the branch. She has been given a date to self-surrender to the Bureau of Prisons by July 10. When her prison term is complete, McDonough will be placed on supervised release for a period of three years, during which time she will be subject to conditions set by the court and monitored by federal authorities.
The case was brought in federal court, where a jury evaluated evidence presented by the U.S. Attorney’s Office. The conviction on counts of embezzlement by a bank employee and transactional money laundering followed the jury’s findings. Sentencing handed down in that same federal jurisdiction imposed the four-year custodial term and the financial restitution order.
Court records show the criminal conduct unfolded over several months while McDonough was entrusted with managerial responsibilities at the branch. Prosecutors emphasized the internal controls she is accused of manipulating — specifically, monthly audits — as the mechanism by which shortages were hidden and withdrawals continued. The investigation and subsequent prosecution sought to address both the financial loss to the institution and the alleged breach of trust involved in the management role.
Under the terms laid out by the court, McDonough must report to prison on or before the self-surrender date set by the court. Following incarceration, the three-year supervised release period will require compliance with conditions typical in federal supervision, and the restitution requirement remains a financial obligation enforced by the court. The sentencing resolves the federal criminal proceedings that followed the internal investigation conducted after her resignation, closing the chapter on the criminal case while leaving the restitution and supervision requirements in place.
U.S. Attorney Timothy Courchaine stated that embezzlement is not a victimless crime, noting McDonough’s actions harmed her employer, the financial system’s integrity, and innocent co-workers whose careers were jeopardized. She was sentenced by U.S. District Judge Susan R. Brnovich on June 10, according to the U.S. Attorney’s Office for the District of Arizona.
A U.S. Attorney’s Office press release says McDonough was convicted on December 11, 2025 of one count of embezzlement by a bank employee, six counts of transactional money laundering, and five counts of structuring transactions to evade reporting requirements.
Prosecutors said the misconduct occurred between June 2021 and February 2022, during which McDonough embezzled $655,000 and deposited or spent approximately $645,000; investigators say she broke larger cash deposits into smaller amounts at different ATMs to avoid triggering mandatory Currency Transaction Reports.
The Department of Justice release reports McDonough (formerly known as Brooke Taylor) was sentenced on June 10, 2026 by Senior U.S. District Judge Roslyn O. Silver, and that the bank’s internal probe placed three other branch employees on administrative leave after the thefts came to light.
The case was investigated by the Federal Deposit Insurance Corporation Office of Inspector General and the Mesa Police Department; Assistant U.S. Attorneys Aron Ketchel and Adriana Genco handled the prosecution under case number 24‑CR‑376, and court records say some stolen funds were spent or attempted to be spent on vehicles, a credit card and cosmetic surgery.
