Oxford Center CEO Tami Peterson was arraigned on a charge of second-degree murder Tuesday after a 5-year-old boy died in a hyperbaric chamber explosion at the facility earlier this year.

Tamela Peterson, 58, of Brighton, is one of three employees charged with second-degree murder with an alternate charge of manslaughter, to be determined by the jury.
