Gr 4-7-A fascinating look at the U.S. Fish and Wildlife Forensics Laboratory where scientists work to solve crimes, such as poaching. The book focuses on a specific incident-the shooting of a bull elk in Yellowstone National Park-and follows the case step-by-step. Interspersed with the story about this killing are "Wild Files" that give further information about the lab, the scientists, and related topics such as endangered wildlife protection laws. These inserts, alternating with two-page spreads of text, contain lots of intriguing information but their placement is a drawback. Although the main story is compelling, its continuity is continuously broken. Otherwise, this is an enjoyable, informative volume with well-placed, clear photos that add interest. Offer it to fans of the author's The Bone Detectives (Little, Brown, 1996) and nature enthusiasts, who will appreciate this foray into an intriguing and little-known area of wildlife conservation work.-Arwen Marshall, formerly at New York Public Library Copyright 2000 Cahners Business Information.

Donna Jackson ( The Bone Detectives , 1996) creates a riveting and thorough account of dedicated people banding together with the help of science and the law to catch an elk poacher. It begins the day before the elk, Charger, is shot in Yellowstone Park and takes the reader through almost two years of detective work more riveting then any television police drama. Jackson focuses on the almost miraculous feats of scientists in the only animal forensic lab in the world as they piece together clues, examining, for example, DNA samples and bullet casings. Those readers clamoring for justice will find satisfaction in the apprehension of the poacher who is punished with jail time and fines. Jackson does not skip lightly around the subject, so the story is often painful and jarring. The treatment is appropriate for children over ten, effectively eliciting an emotional reaction that is educational as well as motivational. Interspersed throughout the story are pages filled with facts about the law, science, poaching, and endangered species. Stunning color photographs from a renowned team graphically illustrate the pages, but do not overwhelm the text. The effect is that of a scrapbook of information with photos that enrich a real-life animal detective story. (ways to help, list of forensic terms) (Nonfiction. 8-10)

In this companion to The Bone Detectives (1996), Jackson introduces young readers to the forensic scientists who track down criminals who harm wild animals. She recounts details of an actual 1993 case involving a bull elk slain for his antlers, which was solved by the scientists at the National Fish and Wildlife Forensics Laboratory in Ashland, Oregon. In a smoothly written text that unfolds almost like a mystery novel, Jackson explains how the detectives analyze clues, make use of sophisticated electronic equipment, and follow tips to solve crimes. Interspersed throughout are Wild Files, sidebars describing current wildlife law, the various jobs in animal crime labs, and efforts to prevent the poaching of endangered species. Engaging full-color photographs help clarify the text and will appeal to browsers. A list of follow-up suggestions and a glossary of terms are appended. A book that will be welcomed by mystery fans and anyone who cares about animals. (Reviewed April 1, 2000)
