An Illinois business belonging to a vocal critic of an embattled Democratic mayor went up in flames earlier this week in what is being investigated as a “suspicious” incident. 

“The fire is suspicious in nature,” Dolton Deputy Fire Chief John Calhoun told WGN. “We do have the fire marshal out here currently with our [mutual aid] arson team.”

The fire began at approximately 6 a.m. on Tuesday and was quickly elevated to a three-alarm response. While no one was injured, the building was completely destroyed, FOX 32 Chicago reported. 

A smaller fire was also reported at the same location last week, according to WGN.

In 2024, the FBI served subpoenas at Dolton Village Hall amid ongoing claims of corruption, but Henyard was not served. She has also faced sexual assault allegations and scrutiny surrounding her cancer charity. 

Following her loss to Mayor-elect Jason House, authorities issued a federal subpoena after launching a criminal investigation tied to a development project involving land owned by Henyard’s boyfriend, according to FOX 32 Chicago. 

House and Henyard did not immediately respond to Fox News Digital’s request for comment.
