A former Schererville, Indiana, insurance agent who wrote more than 2,000 fraudulent life insurance policies in the names of hundreds of people, most of them retirees and elderly residents of Northwest Indiana, has been sentenced to 70 months in federal prison. Thomas J. Lemmen, 51, was sentenced on September 2, 2026, after pleading guilty to wire fraud, the U.S. Attorney’s Office for the Northern District of Indiana said. The court also ordered two years of supervised release and $1,601,505.27 in restitution to victims.
A trusted local agent and more than 2,000 fake policies
Lemmen worked as a licensed independent insurance agent in Indiana beginning in 2012, according to documents in the case. Between 2020 and 2022, prosecutors said, he used that position to run a Ponzi-style scheme that let him profit by writing high volumes of fraudulent life insurance policies.
On thousands of separate occasions, Lemmen wrote life insurance policies in the names of current, former and prospective clients without their knowledge or consent. To do it, he used sensitive personal information, including names, dates of birth, Social Security numbers and details about their family history. He also forged the digital signatures of the supposed applicants on legal documents, among them medical records releases that caused victims’ private medical and pharmaceutical information to be disclosed to insurance companies.
The money came from commissions. Each time Lemmen wrote a new fraudulent policy, he collected a commission payment. In all, federal prosecutors said, he received more than $5 million in commissions to which he was not entitled. He used the proceeds to keep the scheme running and for personal spending, including home furnishings and renovations, an outdoor pool at his home and frequent travel.

Victims here learned that an agent had used their names, birth dates and Social Security numbers without permission, and the free credit-freeze steps and a fraud evidence and report log help a household lock down credit and document what was taken, in The Senior Fraud Defense & First-Hour Recovery Kit.
How the scheme stayed hidden for more than two years
Prosecutors said Lemmen took sophisticated steps to make the fictitious policies look legitimate and avoid detection for over two and a half years. Because the policies were written in the names of real people, with real identifying details and forged signatures, they could pass through ordinary underwriting while the people named on them had no idea they existed.
That is part of what made the case especially harmful to older residents. Many retirees had shared their Social Security numbers, birth dates and family history with Lemmen in the ordinary course of buying coverage or discussing it. Prosecutors said he turned that information against them, making them identity-theft victims and exposing private medical and pharmacy history to insurers they had never approached.
The Indiana Department of Insurance acted before the criminal case was resolved. In April 2023, the department took administrative action to prevent the renewal of Lemmen’s license to sell insurance in Indiana, according to the federal prosecutors.
What officials said at sentencing
U.S. District Judge Gretchen S. Lund imposed the sentence. United States Attorney Adam L. Mildred said the case was a betrayal of people who had relied on Lemmen to protect their families.
“Hundreds of people trusted Thomas Lemmen to write life insurance policies to protect themselves and their loved ones. But he betrayed that trust and fraudulently obtained millions of dollars to which he was not entitled,” Mildred said. “Thanks to the combined efforts of the FBI, the United States Bankruptcy Trustee for Region 10, and Assistant United States Attorney Zach Heater, the public can see that those who choose to commit fraud will be held accountable.”
FBI Indianapolis Special Agent in Charge Timothy J. O’Malley pointed directly to the impact on seniors. “Lemmen took advantage of his position and ripped off a lot of people – including seniors – just to line his own pockets. He took information people trusted him with and used it against them. These people thought they were protecting their families, and instead, he made them victims,” O’Malley said.
The FBI investigated the case with assistance from the United States Bankruptcy Trustee for Region 10. Assistant U.S. Attorney Zachary D. Heater prosecuted it.
Lessons for older policyholders and their families
The Lemmen case is unusual in scale, but the weak point it exposed is common. Buying life insurance, annuities or Medicare supplement coverage usually requires handing an agent some of the most sensitive details a person has: a Social Security number, date of birth, medical history and information about family members. Retirees who have worked with the same local agent for years may never think to check what is being done with that information.
A few habits can make misuse easier to spot. Policyholders can keep copies of every application they actually sign and compare them against any policy documents, premium notices or insurer letters that arrive in the mail. Unexpected mail from an insurance company, or a request to authorize release of medical records for coverage that was never requested, deserves a call directly to the insurer using a number from its official website rather than one supplied by the agent.
Consumers can confirm an agent’s license status and file complaints with their state insurance regulator, such as the Indiana Department of Insurance. When identity theft is suspected, reports to the insurer, the state regulator and law enforcement create a paper trail that can matter later. Older adults and their families can also reach the Justice Department’s National Elder Fraud Hotline at 1-833-FRAUD-11 (1-833-372-8311) for help reporting suspected fraud.
The restitution order in the Lemmen case applies to the victims of that offense as determined by the court. It does not create a claims program for the general public.
When personal details handed to an agent are turned against the client
The retirees in the Lemmen case did nothing unusual; they shared the same information every insurance applicant shares. The gap the case exposes is what a household does in the first hours after discovering that its identity has been used without consent.
