The Brief The family of Thomas Cooper, who died in a Troy hyperbaric chamber explosion, is filing a $100 million lawsuit against eight defendants, including the chamber's manufacturer and the facility. The lawsuit, filed by Fieger Law, seeks to hold those responsible accountable for the death and secure damages for the family. After Thomas Cooper died earlier this year while inside a hyperbaric chamber in Troy, his family retained Fieger Law to represent them in court. Fieger Law announced the lawsuit on Monday, seven months after initially being retained by the family. In announcing the lawsuit, Fieger Law named eight defendants in the lawsuit, including the four people who were charged in criminal court.
