CARLYLE — A search warrant executed by the FBI revealed the target of a
criminal probe was then Carlyle Police Chief Mark Pingsterhaus, who
leased office space in the police station to a federal task force that
battles public corruption in southern Illinois.
The FBI is investigating Pingsterhaus, a 30-year law enforcement
veteran, for possible wire fraud and theft of federal funds, according
to the search warrant, obtained by Capitol News Illinois and the
Illinois Answers Project. The FBI rents space in the Carlyle police
station in downstate Clinton County.
No criminal charges have been filed against Pingsterhaus, who resigned
in December, and neither the city nor the FBI would discuss the nature
of the allegations.
Pingsterhaus could not be reached for comment.
In November, under the Illinois Freedom of Information Act, the two news
organizations requested a copy of any search warrant served on the city
after a press release posted on the city’s Facebook page publicly
confirmed a federal investigation into Pingsterhaus.
Carlyle City Administrator Brad Myers initially declined multiple
requests from reporters for a copy of the search warrant, but eventually
provided one last week — more than two months later.
U.S. Magistrate Judge Reona J. Daly signed the search warrant on Nov.
12. It stated the FBI sought financial records from Pingsterhaus’ office
at the Carlyle Police Department, including cash, receipts, ledgers and
lease agreements related to expenses paid with city funds. It further
sought records of checks, credit cards, gift cards and petty cash.
The search warrant also sought any correspondence, gifts, keys,
photographs or other items “indicating a personal relationship or
travel” with a person whose name was redacted by Myers, who stated the
person was a “private citizen.” Reporters have learned she is a public
official in a neighboring county.
The FBI requested police department expenses dating back to 2012, when
Pingsterhhaus became chief, and payroll, leave information and travel
authorizations and reimbursements for Pingsterhaus starting in 2024.
They also requested Pingsterhaus’ personnel record, in a subpoena dated
six days after the search warrant.
The search warrant included a photo of Pingsterhaus’ office door at the
Carlyle police station — just steps away from the home of the FBI’s
Southern Illinois Transnational Organized Crime West Task Force, or
TOC-W. Pingsterhaus signed the lease with the FBI to house the task
force in 2021.
The arrangement was mutually beneficial. Both agencies had a similar
mission; Carlyle police patrolling and investigating crimes in the
Clinton County town of around 3,200, and the TOC-W Task Force focusing
on international drug trafficking rings operating in southern Illinois,
as well as money laundering, murder, extortion, kidnapping and public
corruption.
The feds agreed to pay up to $180,000 renovation costs and $3,750 a
month in rent to the city for space in the police station located just
down the street from Carlyle Lake, a state recreation area, under the
terms of the lease obtained under the Illinois Freedom of Information
Act.
Though the 12-member federal task force would have their own office
secured behind a keypad, task force members and Carlyle police officers
would heat up leftovers in the same microwave of a shared kitchen; pass
each other going in and out of meetings of the shared conference room,
and use the same restrooms.
Two other federal agencies provide investigative assistance to the task
force, including the Drug Enforcement Agency and Homeland Security
Investigations — the investigative arm of Immigration and Customs
Enforcement, or ICE.
For years, the local police and federal agents quietly shared the space.
Then, on Nov. 19, 2025, city officials received word of an ongoing FBI
investigation of Pingsterhaus. Neither Mayor Judy Smith nor city
administrator Myers would discuss the nature of the investigation.
Search for the search warrant
A week after the federal investigation became public, Capitol News
Illinois and the Illinois Answers Project requested a copy of the search
warrant and Myers initially said he “cannot provide any information” on
the matter involving Pingsterhaus because “it is still an active FBI
investigation.”

On June 9, 2023, the city posted a photo of Mark Pingsterhaus
shaking hands with then FBI Director Christopher Wray, heralding
Pingsterhaus completing the FBI Academy. Pingsterhaus later was
suspended amidst an FBI investigation. (City of Carlyle Facebook
page.)
A month later, Myers said in a Dec. 22 email that the city was not in
possession of a search warrant served on its police department. Myers
later provided a copy to the Attorney General’s Public Access Counselor
in response to a request by reporters to review Myers’ denial.
“I was in the process of writing you a reply on Friday afternoon and
decided to look through all my paperwork, one more time, to ensure that
I, in fact, did not have nor have I ever received a search warrant for
the city of Carlyle. As I was reviewing my files again, page by page, I
did in fact discover that I do have a copy of the search warrant,” Myers
wrote in an email to the public access counselor attorney Shannon
Barnaby.
Reporters received a copy of the search warrant by email the same day as
Barnaby.
The city also provided a copy of Pingsterhaus’ personnel records. Those
records included a letter from Smith, the mayor, to Pingsterhaus dated
Nov. 25 that referenced a visit Pingsterhaus made to Smith’s house a few
days after he was placed on leave.
“During our discussion, you informed me of your desire to resign in lieu
of being terminated,” Smith wrote. “I do intend to remove you from your
position of police chief due to the allegations and your admissions of
wrongdoing.”
Those specific wrongdoings that Pingsterhaus admitted to Smith have not
been made public.
Smith then warned Pingsterhaus to stay away from the police station and
city hall and submit his resignation within seven days or he would be
fired. On Dec. 1, Pingsterhaus resigned his $115,000-a-year position in
a one-line letter. Last month, he also withdrew his bid to become the
Republican candidate for Clinton County sheriff.
Efforts to reach Pingsterhaus over the past two months have been
unsuccessful. Reporters showed up at his house in late November, just as
a black pickup pulled into the driveway. As a reporter approached, the
driver, who resembled Pingsterhaus, put the truck in reverse, backed out
of the driveway and left the area. In December, a no-trespassing sign
was seen near his front door.
Pingsterhaus’ law enforcement career began in 1995 with the Breese
Police Department, becoming a full-time officer two years later. He also
joined the Clinton County Sheriff’s Office on a part-time basis. In
November 1997, he went to work for Carlyle and became chief in 2012.
Just 18 months before the announcement that he was the target of a
federal investigation, Pingsterhaus graduated from the FBI Academy — a
10-week leadership and development course at the bureau’s headquarters
in Quantico, Virginia, that emphasizes leadership, academics and
physical fitness for senior law enforcement officers.
Earlier this month, Jason Herzing, a long-time member of the FBI task
force on loan from the Carlyle Police Department, was named the new
police chief with a $100,000 annual salary.
