This book covers the Johnson family: Duane, Sandy, Sherrie, and Michael. The family lived in Omaha, Nebraska. The family took ill suddenly one September morning, exhibiting symptoms of food poisoning or flu. Three other members of the family stopped by, but left promptly once Sandy told them she thought her family had the flu. Those three members became ill later that same day, exhibiting the same symptoms. One of those, an 11-month-old boy, died. Duane died the day after his nephew. A subsequent investigation into the root of the mysterious illnesses led back to the Johnson house, where tainted lemonade was determined to be the culprit. All signs pointed to a deliberate poisoning by DMN, a highly toxic chemical that can alter DNA and cause cancer. I won't spoil the book with the identity of the poisoner, but it was an interesting investigation. This book was informative and included more details than the episode of Forensic Files that it was on.
