Jeffrey Mosteller, 64, of Clinton Township; Gary Marken, 65, of Spring Arbor; and Aleta Moffitt, 60, of Rochester Hills, last appeared in court on May 28.
Peterson, along with Mosteller, the safety manager, and Marken, the primary management assistant, are charged with second-degree murder. They were also given the alternative charge of involuntary manslaughter, which means that a jury will decide which charge accurately fits their conduct.
Moffitt, who was allegedly operating the hyperbaric chamber at the time of the explosion, was charged with involuntary manslaughter and falsifying medical records.
