Hard Evidence: How Detectives Inside the FBI's Sci-Crime Lab Have Helped Solve America's Toughest Cases

True-crime fans will savor this room-by-room, machine-by-machine tour of the FBI Criminal Laboratory in Washington, D.C., perhaps the world's best forensics department. Fisher (Killer) introduces readers to units that involve chemistry (with a special emphasis on toxicology), explosives, hairs and fibers, fingerprints and DNA analysis, material analysis, documents, firearms, photography, video enhancement and polygraphy. Included are details of the ballistic investigations of the assassination of John Kennedy, the attempted assassination of Ronald Reagan, the murder of Martin Luther King, and the World Trade Center bombing. Readers will be astounded by the abilities of the high-technology equipment and the talents of the investigators who staff this extraordinary sci-crime lab. Photos not seen by PW. (Apr.)
