A Lake St. Louis accountant is accused of quietly bleeding her St. Louis County employer dry over nearly seven years, allegedly funneling about $1.2 million in company money into personal luxuries before federal investigators stepped in.
Prosecutors say 44-year-old Kari Bertels turned herself in on Monday, then pleaded not guilty to five counts of wire fraud in federal court. The indictment claims her alleged scheme ran from Oct. 9, 2018, through Jan. 12, 2026, and revolved around repeated, unauthorized swipes of a company credit card.
According to prosecutors, those charges turned into a long-running shopping spree that covered an array of personal expenses totaling roughly $1.2 million. The indictment cites about $19,815 at Red Aspen, $16,512 for fitness coaching, $42,407 in DoorDash orders, $59,994 on Amazon, $27,044 on Instacart, $14,331 in jewelry, $15,000 in airfare, and $14,110 spent at a Sandals resort, according to the U.S. Department of Justice.
Prosecutors say Bertels did not just spend the money; she allegedly worked to cover her tracks. According to the indictment, she is accused of redirecting company credit card statements, skipping monthly expense reports, and breaking up charges into smaller entries inside the company’s accounting system.
Bertels was employed as an accountant and senior financial analyst, with responsibilities that included approving expense reports and paying the company’s bills, the local report says. The employer, headquartered in St. Louis County, was not publicly named in court filings, as reported by STLtoday. The U.S. Postal Inspection Service handled the investigation, and the U.S. Attorney’s Office for the Eastern District of Missouri is prosecuting the case.
Legal Process and Potential Penalties
The federal indictment, returned on April 29, charges Bertels with five counts of wire fraud. Each count carries a maximum of 20 years in prison and a fine of up to $250,000, according to the U.S. Department of Justice.
After surrendering on Monday, Bertels appeared in federal court and entered a not-guilty plea. Assistant U.S. Attorney Karin Schute is listed as the prosecutor. Any decisions on trial scheduling, restitution, or forfeiture will come as the case moves through the system.
What This Means for Local Employers
For businesses across the region, the case is a textbook example of what can happen when one person has too much control over the books and not enough oversight. Weak segregation of duties and cursory reviews of routine expenses can let fraud simmer in the background for years.
Financial-control breakdowns have fueled other high-profile fraud prosecutions in Missouri in recent years, including alleged misuse of nonprofit meal program funds, according to The Associated Press. In response, many organizations tighten audits, require dual approval for large or unusual charges, and keep a closer eye on vendor and credit card statements.
For now, prosecutors stress that the investigation is still underway and that the charges are only allegations. Bertels, like any defendant in a criminal case, is presumed innocent unless and until she is proven guilty in court.
