When playing in the park with her parents, Sarah was suddenly and inexplicably terrified by something and started to hyperventilate. Jim sat her down and guided her breathing to calm her down.
Sarah was later put in the hospital and treated with chemotherapy, causing her to lose her hair. Her father stayed with her in bed and read her the children's novel Anne of Green Gables by L.M. Montgomery. She later passed away in the hospital as her parents watched. The doctors tried to revive her with CPR to no avail.
