Jaina is the real ife character in two books, "Thirtymile Fire," as the sister to Karen, "Angel Promises," and now, "Whatever Happened to the Zodiac Killer." The character, "Lindy" in "New Zodiac" is all grown up. She was the baby I was pregnant with the night we chased the "Zodiac Killer." Although the "New Zodiac movie" is strongly based on a true story, many of the names of the true life people have been changed due to some fictionalization of the story. I would say it's about 95% true story, with a fictional ending and some bridging work.
