The Michigan Attorney General’s Office charged four people in connection to the death of a 5-year-old boy who was killed in an explosion inside a hyperbaric chamber.

Three of the people — Oxford Center owner Tami Peterson, safety director Jeffrey Mosteller and director of operations Gary Marken are charged with second-degree murder and involuntary manslaughter in the death of Thomas Cooper, Michigan Attorney General Dana Nessel told reporters at a press conference Tuesday. A fourth person, Aleta Moffitt, who was operating the chamber at the time of the fire, stands accused of involuntary manslaughter and intentionally putting false information on a medical form.

Hyperbaric treatment experts consulted the AG’s office and came to some “horrifying” conclusions, Nessel said.

According to Nessel, the chambers at the center were beyond their service time and should not have been used. There were no daily maintenance checks nor any safety supervisors on site or a licensed technician operating the machine, Nessel said.

Nessel said the center ignored safety protocols to prevent fires from occurring in the highly flammable chambers.

“The investigation into this tragedy has revealed how the Oxford Center in Troy and several of its key decision makers held safety among their lowest considerations in hyperbaric treatment practices,” Nessel said.

The attorney general argued that second-degree murder charges are appropriate because the trio acted in “wanton and willful disregard of the likelihood that the natural tendency of said act would result in death.” Nessel alleged the defendants “knowingly created a very high risk of death or great bodily harm.”
