Officials say hidden cameras were placed in a red-light therapy room at the clinic.
BATAVIA, Ill. — A Batavia chiropractor has been charged after investigators said he secretly recorded nude or partially unclothed patients at his office, capturing images of more than 180 people, including children. David Hanson, 43, was arrested after searches at his home and clinic last week, authorities said.
Officials said the case matters because it involves alleged hidden surveillance inside a health care setting and a large number of potential victims across several years. Prosecutors said forensic work is ongoing to identify and notify patients who may have been recorded, while police and the state’s attorney’s office continue to process devices taken from the site. Court records show Hanson is being held as the investigation moves ahead, and civil attorneys began filing lawsuits this week on behalf of former patients.
According to prosecutors, investigators executed search warrants on Hanson’s residence and Hanson Family Chiropractic at 1928 W. Wilson St. in Batavia the evening before charges were announced. Authorities said numerous recordings appear to have been made in a “red light” therapy room used for red and near-infrared light treatments. Kane County State’s Attorney Jamie Mosser said cameras were concealed in the space, adding they were “hidden behind vents or fans so that they would not be seen by the patients.” Officials said the earliest known recording dates to 2017 and that forensic analysts are reviewing data embedded in the files to determine when videos were created and accessed. Mosser also said separate videos of child sexual abuse material, unrelated to chiropractic care, were found during the searches.
Hanson is charged with producing child pornography (five counts), disseminating child pornography (three counts), possessing child pornography (six counts), and unauthorized video recording of a minor through or under clothing (three counts), according to charging documents summarized by prosecutors. Authorities said more than 180 victims have been identified so far, with the youngest reported to be 3 years old. Investigators said many of those recorded were women and girls. The Batavia Police Department led the probe alongside the Kane County State’s Attorney’s Office child exploitation unit. Officials said specialized tools, including an electronics-detection K-9 team from Lake County, assisted in locating devices.
Public records and prior statements provide additional context. Prosecutors have said most recordings appeared to be made inside the therapy room, while other devices were “placed throughout” the clinic. Hanson owns the practice and was taken into custody after the searches. Authorities said the office remained closed during the evidence collection process. While investigators described the room where many of the videos were made, they have not publicly detailed how many cameras were recovered or how often recordings occurred. Officials have not announced findings that any recordings were shared beyond the charged counts, and they said some materials discovered were unrelated to the clinic.
In court, a judge ordered Hanson detained pending further proceedings. His next hearing was scheduled for Nov. 10. Separately, civil action began to build this week. A class-action complaint was filed on Nov. 11 in Kane County on behalf of a former patient, and additional individual lawsuits followed. On Friday, Nov. 14, two women identified as Jane Doe plaintiffs filed suits alleging they were secretly recorded while undressed at the practice. The civil filings name Hanson and his clinic and, in at least one case, the building owner. None of the suits had been resolved as of Friday.
Outside the courthouse and online, officials asked anyone who believes they were affected to contact investigators, while stressing that the criminal case is in its early stages. “Many of the recordings appear to be taken from a red light room,” Mosser said, noting analysts will review metadata to build a timeline. Neighbors near the Wilson Street strip and some former patients expressed shock in interviews with local outlets. Police said their priority remains identifying victims and cataloging devices while prosecutors prepare the case for presentation to a grand jury if needed.
As of Friday evening, Hanson remained in custody and prosecutors said their review of seized electronics continues. Investigators said they will provide updates after additional forensic work and identification efforts, with the next court milestone expected the week of Nov. 10.
