Trace Evidence: The Hunt for the I-5 Serial Killer

Some books about serial killers are dramatic and emotional. Trace Evidence, by contrast, has a steady relentlessness that allows the reader to become fascinated by the characters of the investigators and the facts of how the evidence was assembled. This killer specialized in picking up his victims along Interstate 5, near Sacramento, California, and he had an odd penchant for snipping at their clothes with scissors. As deaths of young women in several different jurisdictions began to form a pattern, a few detectives with contrasting approaches (excitable and given to hunches vs. cool and logical) formed a team. Author Bruce Henderson relates how they followed through on a bewildering number of leads, how they ranked their potential suspects on a point system that proved remarkably effective, and how, finally, a trace evidence expert spent many long hours looking through a microscope to cinch the case with analysis of fibers. Trace Evidence is skillfully structured, emphasizing the investigation rather than the trial, and includes crisp photographs of the key evidence. It would have been a better book if the author had included a timeline of the crimes and a map of the area, but that is a small nitpick about an excellent work of journalism. --Fiona Webster
