California Attorney General Rob Bonta announced on September 21, 2026, that Maki Martinez-Gruninger pleaded guilty to a felony Medi-Cal fraud charge and will serve two years in state prison. State investigators found that she took more than $400,000 from California by secretly enrolling as the paid in-home caregiver for a disabled family member, while another relative was the one actually providing the care. The false claims stretched back to 2007 and went on for more than a decade before they were discovered.
How a secret caregiver enrollment drew Medi-Cal money for years
The case began with a tip from inside the family. According to the Attorney General’s announcement, the California Department of Justice received a complaint alleging that Martinez-Gruninger had fraudulently claimed to be the In-Home Supportive Services provider for a disabled family member. The person who filed that complaint was the disabled relative’s sole caregiver.
That caregiver discovered in December 2019 that Martinez-Gruninger had secretly applied to become the relative’s IHSS provider in November 2007. From then on, the state said, Martinez-Gruninger submitted false claims to the IHSS program for more than ten years, drawing payments for care she was not providing.
In-Home Supportive Services is the California program that pays caregivers, frequently relatives, to help low-income older, blind and disabled residents stay safely in their own homes instead of moving into a facility. The program is funded largely through Medi-Cal, the state’s version of Medicaid, which is why the case was prosecuted as Medi-Cal fraud. Because payments go to whoever is enrolled as the provider, a person listed on the paperwork can collect the money while someone else does the daily work of bathing, cooking, driving to appointments and managing medications.
When the fraud is inside the family. Cases like this one tend to surface only when a relative starts writing down dates, notices and names, and a fraud evidence and report log gives that effort a single place to live in The Senior Fraud Defense & First-Hour Recovery Kit.
The guilty plea and the $413,643 in false claims
The investigation determined that Martinez-Gruninger unlawfully took money from the state’s Medi-Cal program, intended to defraud the State of California, and presented false IHSS and respite-care claims totaling $413,643.30. Respite care is short-term relief meant to give a regular caregiver a break, so the billing covered both routine care hours and temporary relief services that the state says she did not deliver.
Martinez-Gruninger pleaded guilty to a single felony count of Medi-Cal false claims. Under the resolution announced by the Attorney General’s office in Oakland, she will serve two years in state prison. The state described the conduct as a scheme that “exploited a disabled family member.”
Bonta presented the sentence as a warning to anyone tempted to bill public health programs for work they do not do. “Those who defraud these vital programs are not just breaking the law,” he said. “They are stealing from taxpayers, endangering patient care, and betraying the public trust. At the California Department of Justice, we will not tolerate it.” He added that the department “will continue to aggressively pursue those who abuse public programs for personal gain and hold them accountable to the fullest extent of the law.”
The length of the scheme is what stands out. The enrollment dated to November 2007, and the family did not learn of it until December 2019, a gap of 12 years in which the paid-provider slot for the disabled relative was held by someone other than the person doing the caregiving.
The state unit that pursues Medi-Cal fraud and elder abuse
The prosecution was handled by the Attorney General’s Division of Medi-Cal Fraud & Elder Abuse, known as DMFEA. The division’s stated mission is to protect the public and the Medi-Cal program from people who defraud taxpayers and divert state health care resources. As its name indicates, it also investigates the abuse and neglect of elderly and dependent adults.
DMFEA receives 75 percent of its funding from the U.S. Department of Health and Human Services, through a federal grant totaling $77,652,892 for federal fiscal year 2026. The remaining 25 percent, or $25,884,297, comes from the California Attorney General’s Office. The federal fiscal year runs from October 1, 2025, through September 30, 2026.
The office credited the outcome to collaboration among government agencies and to members of the public who report suspected Medi-Cal fraud or elder abuse. In this case, the decisive report came from the relative who had been providing care all along without being the enrolled provider, which illustrates how often these schemes depend on someone close to the situation noticing that the paperwork and reality do not match.
What families caring for a disabled or older relative can watch for
The case carries a practical lesson for older Californians and for the adult children, siblings and spouses who look after them. Home-care programs such as IHSS send money to whoever is enrolled as the provider, not necessarily to whoever is doing the work. A disabled or elderly recipient may not realize that a different relative has been placed on the paperwork, especially when that relative handles the household mail, benefit correspondence or bank accounts.
Family members who share caregiving duties can reduce that risk by keeping copies of program notices, knowing which county office administers the recipient’s case, and confirming with that office who is listed as the provider. A caregiver who is doing the work but is not enrolled is not only exposed to this kind of fraud but may also be missing payments the program is designed to provide.
Suspected Medi-Cal fraud or elder abuse can be reported directly to the Attorney General through the DMFEA reporting page. The Martinez-Gruninger case shows that a complaint filed long after a scheme began can still lead to a felony conviction and prison time. It also shows the cost of a late discovery: by the time the sole caregiver learned of the enrollment, public money meant for a disabled person’s care had been flowing to someone else for more than a decade.
When a relative’s care money may be going to the wrong person
The Martinez-Gruninger scheme came to light because one caregiver noticed a mismatch and reported it. Families who suspect something similar need a clear, dated account of what they found and whom they told, kept in one place from the first day.
