A Grayslake auto shop is facing a wrongful death lawsuit in McHenry County. The legal action follows the carbon monoxide poisoning deaths of Kirby Graham and Yeisimar A. Morales Sanchez in Crystal Lake.
The November 4 tragedy on Coventry Lane
The fatal incident occurred on November 4, 2025, at approximately 12:56 a.m. in Crystal Lake. According to the report, Kirby Graham was positioned in the driver's seat of his parked vehicle on Coventry Lane, while Yeisimar A. Morales Sanchez sat in the front passenger seat. Both individuals died from carbon monoxide poisoning, a tragedy that has led the family of the 20-year-old victim to seek legal recourse.
The core of the tragedy lies in the vehicle's condition prior to the incident.. The victims were inside a car that had recently been serviced, yet the environment inside the cabin became lethal due to exhaust infiltration. This specific event has now become the center of a legal battle over professional negligence and public safety.
Violations of the Illinois Automotive Repair Act
An amended complaint filed on October 1 in McHenry County alleges that Amerimex Mufflers, Brakes & Auto Repair Inc. failed in its duty to the customer. The lawsuit claims that Kirby Graham had brought his vehicle to the Grayslake business specifically for an exhaust system inspection. Despite this, the business allegedly allowed the car to leave the facility without fixing a critical defect or warning the driver about the danger of carbon monoxide entering the passenger area.
The legal filing accuses Amerimex Mufflers, Brakes & Auto Repair Inc. of negligence and direct violations of the Illinois Automotive Repair Act. The estate of Yeisimar A. Morales Sanchez, represented by attorney Guy D. Geleerd Jr., is seeking more than $100,000 under two separate counts: a survival action and a wrongful death claim. As reported by FOX Chicago, police investigators confirmed that the occupants received no warning about the defective exhaust system before entering the vehicle.
Six similar US deaths in two years
This case is framed not as an isolated error, but as part of a systemic failure in the automotive repair industry. Attorney Guy D. Geleerd Jr. has identified at least six similar incidents across the United States over the last two years where faulty exhaust systems led to carbon monoxide fatalities.. These patterns suggest a broader trend of inadequate safety screenings at repair shops nationwide.
Two specific parallels highlight this danger. In Florida, the family of 21-year-old Allwyn Thompson Jr. alleged that a Kia Forte's exhaust leak went undetected through multiple inspections in 2024. Similarly, in Texas, the family of 20-year-old Jesus Marines sued a San Antonio dealership over an undisclosed defective exhaust system in a Ford Mustang. These cases underscore a recurring failure to identify and disclose lethal defects before vehicles reach the consumer.
Amerimex Mufflers' legal position and insurance status
While the allegations are detailed in the McHenry County filing, several critical pieces of information remain unknown. Guy D. Geleerd Jr. has stated that he is still waiting to learn the official legal position of Amerimex Mufflers, Brakes & Auto Repair Inc. It is currently unclear if the business has retained legal counsel to fight the claims.
Furthermore, the extent of the financial recovery for the victims' families remains uncertain, as the attorney is still assessing how much insurance coverage is available to address the claims.. The lawsuit currently relies on the claims presented by the estate, and the defense's version of the exhaust inspection has not yet been made public.
