A federal jury in Sacramento has convicted the general manager of the Viva Supermarkets grocery chain of conspiracy, immigration document fraud, and obstructing two U.S. Department of Labor wage investigations, according to the U.S. Attorney’s Office for the Eastern District of California announcement on October 14, 2026. The verdict makes Karla Montoya, 45, of Sacramento, the only defendant in the long-running Viva case to be found guilty at trial; the chain’s owner and two other company officials have already pleaded guilty.
According to the government, Montoya worked with Viva owner Shahriar “Sean” Loloee, a former Sacramento City Councilmember, to staff the chain’s Sacramento-area stores with workers who were not authorized to work in the United States. Prosecutors said she knowingly accepted counterfeit Permanent Resident cards and Social Security cards from numerous employees during hiring, used false immigration documents herself, and helped run off-the-books pay practices that denied workers overtime.
The obstruction counts stem from two Wage and Hour Division investigations the Labor Department opened in 2020. Prosecutors said Montoya and Loloee hid employees who were likely to give investigators unfavorable information and interfered with investigators at the stores. Earlier charging documents alleged that the defendants made false statements to investigators, listened in on an employee interview to influence the testimony, told an employee to lie about her hire date, and had workers hide from investigators. The government says that obstruction caused the earlier investigation to substantially understate the back wages owed to workers. The releases do not say how many workers were involved or put a dollar figure on the unpaid wages.
The jury returned its verdict after an 11-day trial before U.S. District Judge Troy L. Nunley, who set sentencing for January 7, 2027. According to the U.S. Attorney’s Office, Montoya faces a maximum of five years in prison on the conspiracy count, 10 years on each false immigration document count, and five years on the obstruction count, plus fines of up to $250,000 per count. The case was investigated by IRS Criminal Investigation and Homeland Security Investigations, with help from California’s Tax Recovery in the Underground Economy (TRUE) Task Force, a joint effort of state tax, labor, and justice agencies.
The case dates to December 2023, when a federal grand jury indicted Loloee and Montoya on 25 counts, alleging a conspiracy stretching back to 2008. Loloee was then a sitting city councilmember. A 58-count superseding indictment in March 2024 added tax, money laundering, and COVID-19 relief charges and two new defendants: Viva controller Mirwais Shams and Ahmad “Shah” Shams, who worked in roles including human resources director. Prosecutors alleged the two altered employee time records tens of thousands of times, cutting the overtime workers were paid.
Loloee pleaded guilty on April 23, 2026, to conspiracy to obstruct a Labor Department investigation, conspiracy to defraud the IRS, three counts of filing false tax returns, wire fraud, and money laundering. In his plea, he admitted that the company kept two sets of payroll books, one for the IRS and one labeled “Excess Payroll,” and paid workers partly in cash and in in-house “Green Checks” that could be cashed only at Viva stores, causing a tax loss of about $200,000. He also admitted giving Labor Department investigators an employee list with falsified, later hire dates in order to hide undocumented workers and reduce the back wages owed, and obtaining about $1.2 million in federal Restaurant Revitalization Fund money by understating his stores’ 2020 sales, then moving $949,900 of it to a trust account in a relative’s name. The Shams pleaded guilty on August 18, 2026, to filing false tax returns. Sentencing for all three is now set for November 19, 2026.
The case illustrates how a civil wage-and-hour audit can become a federal criminal prosecution. Under federal law (8 U.S.C. § 1324a), employers must verify each new hire’s identity and work authorization on Form I-9, and they meet that duty if the documents presented reasonably appear genuine on their face. An employer that accepts documents in good faith is generally protected. What the government says it proved here is different: a manager who knew the documents were fake and accepted them anyway, then worked to keep federal investigators from talking to the affected workers. The case also shows that individual managers, not just owners, can face personal criminal exposure.
