Key Points:
- Jeffrey Mosteller, 66, was sentenced to 19 months in prison after pleading no contest to involuntary manslaughter in connection with the death of 5-year-old Thomas Cooper, who died in a hyperbaric oxygen chamber explosion at the Oxford Center in Michigan.
- The explosion occurred in January 2025 during treatment for Cooper’s sleep apnea and ADHD, with prosecutors accusing the center of disregarding safety protocols set by the National Fire Protection Association and the chamber’s manufacturer.
- Mosteller, the safety manager at the center, was one of four former employees charged; the clinic owner and management assistant face second-degree murder or involuntary manslaughter charges, while the chamber operator was charged with falsifying medical records.
- The other three employees have pleaded not guilty and are awaiting trial, while Cooper’s family has filed a $100 million civil lawsuit against the Oxford Center and the chamber manufacturer.
- Michigan Attorney General Dana Nessel emphasized the preventable nature of the tragedy and expressed hope that the conviction brings some justice to the boy’s family.
