Troy Police Detective Ryan Whiteside said he collected and reviewed video footage of 5-year-old Thomas Cooper's three dozen hyperbaric oxygen therapy appointments at the Oxford Center in Troy between Dec. 9, 2024 and Jan. 31, 2025, the day he was burned to death while trapped inside a hyperbaric chamber.
