In February 2025, the Westfield Police Department (WPD) initiated an investigation into Mister Mancave LLC, a local business allegedly selling counterfeit autographed sports memorabilia through its online store and various other platforms. The investigation began after a woman in North Carolina reported receiving fraudulent merchandise from the company.
As the case progressed, additional victims were located, each claiming to have purchased autographed memorabilia from Mister Mancave that was later determined to be counterfeit.
On Tuesday, July 15, Westfield Police executed a search warrant at the Mister Mancave business location in connection with the suspected fraudulent scheme. The following day, Wednesday, July 16, the investigation extended to a residence in the 300 block of Hoover Street. Upon arrival at the residence, officers discovered an individual deceased from an apparent self-inflicted gunshot wound.
That individual has been identified as Brett Lemieux, 45, Westfield, the founder of Mister Mancave LLC and the primary suspect in this case.
WPD acknowledges that any loss of life is a tragedy, and the department extends its condolences to Mr. Lemieux’s family and friends during this difficult time.
A significant quantity of evidence was collected during the searches, including documentation and items related to the alleged counterfeit operation. Investigators are also aware of a social media post made by Mr. Lemieux shortly before his death, in which he gave specific details and named other individuals who may have been involved. This will require additional time to carefully review and investigate all evidence and leads. Investigators are working with various authenticators for technical assistance and the authentication of all seized items.
Again, this remains an active and ongoing investigation, and WPD will give further updates as details unfold.
The Federal Bureau of Investigation (FBI) is assisting, and WPD appreciates that continued partnership. In October 2024, WPD assigned one of its detectives part-time to the FBI White Collar Crimes Task Force, strengthening the department’s ability to pursue complex financial and fraud-related crimes. This case is a powerful example of how partnerships and proactive planning can dramatically expand WPD’s ability to serve and protect.
WPD is proud of the professionalism and persistence its detectives and officers have demonstrated throughout this investigation and commend their passion for serving. WPD also thanks law enforcement partners at the Carmel Police Department, Fishers Police Department, and the Hamilton County Sheriff’s Office for their valuable assistance in this case.
No additional information will be provided at this time; updates will be made as they become available.
