Hearing: Judge needs more time to make decision in Oakland County hyperbaric chamber explosion case

The prosecution and defense attorneys gave closing arguments on Tuesday, Jan. 20, 2026, in the preliminary hearing against four Oxford Center workers, and the judge said she needs more time to decide whether to bind the case over. Tamela Peterson, 59, of Brighton, Jeffrey Mosteller, 65, of Clinton Township, Gary Marken, 66, of Spring Arbor and Aleta Moffitt, 61, of Rochester Hills, were charged after Thomas Cooper was killed when the hyperbaric chamber he was receiving treatment in exploded at the Oxford Center in Troy on Jan. 31, 2025. The boy’s mother was also injured in the explosion. Oakland County Judge Maureen McGinnis said she has reviewed the evidence but needed more time to consider the final arguments and determine whether they affect her decision. A date for her ruling in this case hasn't been set.
