Tate, who played Julie in the 9-1-1 spinoff’s pilot episode that aired on Oct. 9, died in her sleep on Sunday. “We’re told Isabelle suffered from a rare progressive neuromuscular disease which confined her to a wheelchair,” reports TMZ. “Her agent says the disease affects the legs but can also affect internal organs such as the lungs and heart. Because of the disease, Tate had basically given up on her dream of acting ... until she got the 9-1-1 role -- her first big booking which was just perfect for her.”
