Phoenix, AZ – In a joint press conference in San Diego today, United States Attorney Timothy Courchaine announced charges against a Peoria man who is accused of fraudulently billing Arizona’s Medicaid agency more than $33 million in one year and using the funds to purchase property and a luxury vehicle.
On Sept. 8, 2026, a federal grand jury in Phoenix returned an 11-count indictment against Maurice Marcell Williams of Peoria, Arizona for health care fraud and money laundering.
The indictment alleges that Williams owned and operated Thinking and Learning Together 2, LLC (TLT), which held itself out as a behavioral treatment provider in Phoenix. According to the indictment, Williams defrauded Arizona’s Medicaid program, the Arizona Health Care Cost Containment System (AHCCCS) by failing to disclose in his initial AHCCCS application his ownership of TLT and his prior criminal conviction, as well as by billing AHCCCS for services that were never rendered. Williams specifically targeted AHCCCS members who were covered under the American Indian Health Care Program (AIHP) fee-for-service plan available to Native Americans. Between May 2022 and May 2023, Williams billed AHCCCS over $33 million and AHCCCS paid Williams approximately $19.7 million based on these false and fraudulent claims. The indictment also includes forfeiture allegations that seek forfeiture of two residential properties, a Rolls Royce Cullinan, and brokerage accounts owned by Williams.
A conviction for health care fraud and money laundering carry a maximum penalty of 10 years in prison for each count of conviction.
On April 7, the Department of Justice announced the creation of the National Fraud Enforcement Division (Fraud Division). The Fraud Division is laser-focused on investigating and prosecuting those who commit fraud against the American people. The Department’s work to combat fraud supports President Trump’s Task Force to Eliminate Fraud, a whole-of-government effort chaired by Vice President J.D. Vance to eliminate fraud, waste, and abuse within Federal benefit programs.
IRS-Criminal Investigation and Homeland Securities Investigation conducted the investigation, with substantial assistance from the AHCCCS Office of Inspector General. Assistant U.S. Attorney Aron Ketchel, District of Arizona, Phoenix, is handling the prosecution.

It is the only federal law enforcement agency with investigative jurisdiction over violations of the Internal Revenue Code. IRS-CI has 16 field offices located across the U.S. and maintains an international presence through attaché posts abroad.
