Continuously serving Kosciusko County since 1854
A Chicago man was arrested for allegedly giving a woman intravenous treatments without having a medical license.
Michael G. Close, 62, Chicago, is charged with two charges of unlawful practice medicine, or osteopathic medicine, level 5 felonies; possession or use of a legend drug, a level 6 felony; and battery, a class B misdemeanor.
He was booked into the Kosciusko County Jail at 7:41 p.m. Thursday on a preliminary bond of $35,500, which was later raised to $100,500.
According to the probable cause affidavit, on Wednesday the Warsaw Police Department received a letter regarding the welfare of a woman. The letter said Close injected the woman with intravenous nicotinamide adenine dinucleotide (NAD) treatments and ran an unlicensed NAD treatment practice from the woman’s home. The letter also said Close’s medical licenses through Illinois was suspended in 2013.
On Thursday, a WPD detective went to the woman’s home and found a black BMW registered to Close. The detective noted intravenous syringes and glass vials consistent with intravenous drugs inside Close’s vehicle. Close admitted he injected the woman with B12 medicine with a syringe and his medical license was suspended. Close also admitted he never received a license to practice medicine through Indiana.
The woman told law enforcement Close brought her medicine in an injectable vial.
Law enforcement searched Close’s vehicle, locating multiple legend drugs.
The detective learned the Illinois Department of Financial and Professional Regulation verified Close did not maintain a medical license or a controlled substance license in Illinois and on March 6, 2026, the Illinois Medical Board maintained Close’s suspension, saying “physician and surgeon license is automatically and indefinitely suspended for a minimum of 12 months due to violation of the department’s May 2021 consent order.”
The detective learned Close was not licensed with the Indiana Medical Board nor the Indiana Controlled Substance Registration from the Indiana Medical Board.
The detective spoke with someone who said between September and December 2025, Close administered drugs to two people via intravenous treatments.
